Moderately hard surface water on the Detroit metro and the western Lake Michigan corridor; very hard well water across the outstate limestone belt and a heavy salt-aerosol overlay across the whole state in winter.

In late 2014 I answered a Craigslist ad placed by a window cleaner in Royal Oak named Frank. Frank had been running a one-truck residential route through the inner-ring Detroit suburbs since 1987 and he wanted to retire. He had about a hundred and twenty active accounts, mostly twice-a-year customers concentrated in Birmingham, Royal Oak, Bloomfield Hills, and Pleasant Ridge. He had a 1998 Ford Econoline that he was throwing in. He wanted twelve thousand dollars for the customer list and the van and his agreement to introduce me personally to the top forty accounts in the spring of 2015.
I drove out to meet him on a Saturday morning in November. He showed me a binder of customer cards going back to 1987 — handwritten notes about every house, every account, the names of dogs that needed to be put up before he started, which back doors stuck, which sprinkler heads aimed at the dining-room window and would need to be turned off the day before service. The binder was, in retrospect, worth more than the twelve thousand I paid him for the whole package. The Econoline died eighteen months later. The customer list, with the binder, is still the foundation of what I do.
I have been running that route, plus a slowly-built second tier of newer customers, since the spring of 2015. Eleven seasons. I have cleaned the same windows in some of the same houses ten times in a row, twice a year. I know which sashes will not open without coaxing. I know which families take down their storm windows in April and which leave them up year-round. I know that the Volvos in Birmingham driveways are aging out toward Teslas and that the housing stock has not aged out at all. That binder is also the reason I have any business writing a piece about cleaning windows in Michigan: I have been doing it on the same routes for eleven years and the work itself is unromantic enough that you actually learn something from it.
This piece is the long version of what I have learned. I am going to walk through the water (which is not the working problem here), the salt (which is), the auto-industry residue that I think is underdocumented in the trade press, the outstate well-water situation that I knew nothing about until I started taking calls from cousins in Lapeer County, the seasonal contaminants in their actual local order, and the closed winter market and what working operators do with it. If you are a homeowner trying to figure out why your windows look the way they do in February, this piece is for you. If you are a cleaner moving into Michigan from out of state, this piece is also for you, and I would suggest you read the section on outstate wells first.
The bulk of the Michigan population — Detroit, all of Wayne County, all of Oakland County, most of Macomb, Washtenaw south of about Ann Arbor proper, and big stretches of southwest Michigan including Grand Rapids — drinks Great Lakes water. The Great Lakes Water Authority pulls from Lake Huron via two intakes (Belle Isle and the dedicated Lake Huron line that comes ashore north of Port Huron) and from the Detroit River at the Springwells plant. The water arrives at the tap at about a hundred and ten milligrams per liter of calcium-carbonate hardness, give or take ten on any given month. That is moderate. That is softer than Chicago's Lake Michigan supply and considerably softer than the deep-aquifer water that you have to deal with in Phoenix or San Antonio.
What this means in practice is that when sprinkler overspray hits the patio doors at one of my Birmingham accounts and dries in the August sun, it leaves a faint film that comes off with my standard squeegee protocol and a five-percent citric pre-treatment on the worst examples. I am not doing the kind of heavy pre-acid work that Mara has to do on collar-county Naperville routes or that Drew has to do in any house in Phoenix. The water, on a route through the Detroit suburbs, is not the dominant problem.
Grand Rapids is similar. Grand Rapids pulls Lake Michigan water through a thirty-mile intake at Port Sheldon and runs about a hundred and twenty-five at the tap. Same playbook as Detroit, more or less. The west Michigan housing stock is a little different (more 1920s-1940s in the city core, more 1950s ranch on the GR periphery) but the water cleans the same.
Ann Arbor and Lansing are the two big-city outliers and they go the other way. Ann Arbor blends Huron River surface water with city wells and runs distinctly harder than Detroit, around two hundred. Lansing is on Saginaw Formation groundwater wells and runs about two-twenty. The protocols I use in Birmingham do not transfer straight across to a route through Lansing's Eastside neighborhood — I would pre-treat more aggressively, run a pure-water rinse on the second pass, and probably price ten to fifteen percent higher to account for the longer per-pane time. I have done day-fill-in work in both Ann Arbor and Lansing and the difference is real.
Outstate Michigan — anything outside a municipal service area — is a different story entirely and gets its own section below. I want to set the urban water question aside first because the inside-the-metro reality is genuinely manageable and the trade press tends to overweight water in the way it talks about Michigan. Salt is the bigger story.
Michigan applies more road salt per lane-mile than most US states. MDOT is one of the heaviest salt-using transportation departments in the country, and the county and municipal road commissions add another layer on top. From the first plow event in late November or early December through the final salt application in early-to-mid March, every plowed road in the state is releasing chloride ions into the air as an aerosol every time a vehicle passes over treated pavement.
That salt aerosol settles on every exterior surface within a few hundred feet of the road. On a house thirty feet off a county road in Bloomfield Township, the ground-floor windows on the road-facing exposure accumulate visible salt residue by the end of January. On a house twelve feet off Woodward Avenue in Royal Oak, the residue is on every accessible exterior pane and a fair share of the second-floor work too. The film is not heavy enough to be obvious on any given day, but it is cumulative and it sets in.
What it does to the glass itself is not the worst part. The salt residue is easy to clean — soap and water lifts it, a clean-water rinse clears it, and a finishing squeegee pass leaves no record. What it does to the frames is the worst part. Aluminum window frames pit visibly within about ten years of salt exposure on a road-facing exposure. The pitting is a slow corrosion that starts as a dulling of the anodized finish and progresses to a chalky white oxide bloom in the corners and along the sash tracks. Once it is there, it does not come off, and the only fix is a replacement frame.
I tell my customers this. I tell them especially the customers in Birmingham and Royal Oak who have aluminum-frame replacement units that went in during the 1990s or early 2000s and who are starting to see the pitting and asking me what I can do about it. The answer is nothing. The salt has been working on those frames for twenty years and what is visible now is the cumulative result. The protocol going forward is to wash the frames every cleaning, at every visit, with the same soap-and-water pass I use on the glass, because keeping the salt residence time short slows the corrosion. It does not stop it. Nothing I do on a window cleaning visit stops corrosion that is already underway. I am not selling anyone a miracle. I am keeping the rate of damage as low as I can.
The post-winter call is the entire spring season for me. From the first week of April through the second week of May, ninety percent of what I am cleaning is salt residue, slush splatter on the lower third of ground-floor windows, and the cumulative grime from a four-month period when nobody opened a sash. The salt comes off in one pass. The slush splatter sometimes takes two, especially where it dried hard on textured glass. The grime around the perimeter of the sash takes a chip brush and patience. None of it is difficult work. All of it is the work I am paid for.
A side note for the cleaners reading this who are running pole-and-pure-water systems in the Detroit suburbs: the salt is going to wear out your hose fittings faster than the rest of the country wears them out. Replace gaskets twice a year, not once. I learned this the hard way around year four and the leaks I was getting in April were entirely a salt-corrosion problem in the brass fittings on my brush pole.
This is the section I think is underdocumented and that I had to figure out from the field. The Detroit metro has a distinctive grime profile that does not match the published profiles for other US metros at the same traffic volume.
The main corridors — Woodward, Telegraph, M-59, I-696, I-94, I-75 through the metro — carry more heavy commercial traffic per lane-mile than the average US metro corridor, and the resulting brake-dust, tire-wear, and engine-particulate fallout is meaningfully higher. Within a quarter-mile of those corridors, ground-floor commercial glass and residential glass on road-facing exposures accumulates a black-to-brown film that is denser than typical urban grime.
The film has three components, in my experience:
Brake dust. Fine ferrous particles that gravity-deposit on horizontal and angled surfaces. Visible as a reddish-brown tint on white painted window frames and on the bottom rail of double-hung sashes. Does not come off with simple water — it needs an acidic pre-treatment, usually a two-to-three-percent citric blend, to chelate the iron and release the particles.
Tire and road-wear particulate. Black rubber and asphalt particles that bond electrostatically to glass. The clean lifts with a normal soap-and-water pass but leaves a faint blue-grey haze that needs an alcohol finish to fully clear.
Diesel and engine particulate. Carbonaceous, fine, and difficult to remove without a solvent pass on the heaviest depositions. On commercial glass within fifty feet of an I-696 ramp, I run an isopropyl-and-citric pre-treatment and then a normal wash. The result is clean. Without the pre-treatment, the result looks acceptable for two days and then the haze returns.
Bigfield, the corridor along Woodward from about Eight Mile to Square Lake Road, is the densest residential exposure to this profile that I service. Houses on the immediate Woodward frontage see the heaviest deposition. Houses one street back see appreciably less. Houses two streets back see what I would call normal suburban urban grime. The gradient is steep and predictable.
I do not pre-treat every house on the route the same way. I pre-treat the Woodward-frontage houses and the Telegraph-frontage houses and the houses backing up to I-696 with the iron-and-particulate protocol; I run the standard residential protocol everywhere else. That difference is built into my pricing structure — Woodward-frontage houses are at the upper end of my range, regular suburban interior streets are at the lower end. Most cleaners I know do not differentiate this way. It costs me about ten minutes per service stop and adds roughly twenty percent to the per-pane revenue on the corridor-frontage houses, which is exactly the right tradeoff in my view.
Until 2018 I had never serviced a well-water house. My route is one hundred percent municipal supply. The first call I took for a job in Almont — about fifty minutes north of where I live — was from a cousin of a customer who needed her windows cleaned before a wedding party and was willing to pay travel. I drove out, ran my standard protocol on the patio doors that the sprinklers had been hitting all summer, and discovered after the first pass that the lower third of every south-facing exterior pane was glowing a faint orange.
That was the first time I had encountered iron staining at any meaningful scale. It is essentially impossible to find in the Detroit suburbs because GLWA water carries almost no iron at the tap. Outstate Michigan, on the limestone-belt aquifers (Marshall Sandstone, Saginaw Formation, the Glacial Drift complex above them), the well water frequently carries elevated iron, dissolved as ferrous bicarbonate at the wellhead and oxidizing to rust-orange ferric oxide on contact with air.
When sprinkler water from a well like that hits glass and evaporates, the iron oxidizes during evaporation and leaves a faint orange tint behind. One application is barely visible. A summer of daily sprinkler overspray builds the tint into a clearly orange band across the bottom of every patio door, ground-floor window, and lower second-floor exposure that the sprinklers reach. Citric acid does not clear it. Vinegar does not clear it. The first time I encountered it I tried both and produced no visible improvement.
What does clear it is phosphoric acid at a controlled concentration, applied carefully, dwelled briefly, and rinsed thoroughly. I now keep a small bottle of three-percent phosphoric in the truck for these jobs. (I will note here that phosphoric will etch limestone trim if you let it run off the glass — which means you have to mask carefully around any masonry trim, and on the Cobblestone-style architecture you find in parts of Lapeer and Genesee counties, the masonry exposure is significant.) Oxalic acid is the other option and is what is sold in commercial rust-remover products for cleaners; I have used it on a few jobs and it works comparably to phosphoric with similar masonry concerns.
The deeper issue is that an iron stain on the glass is downstream of a softener system that is either not present or not functioning. The right answer for the homeowner is to install or service a water softener with an iron-rated resin. I tell my outstate customers this — I am not in the water-treatment business and I am not selling them anything, but if they ask why the staining keeps coming back even after I clean it, the answer is that I am cleaning a symptom and the source is downstream of their well pump.
The geographic spread of the iron problem covers most of the state outside the GLWA service area. The thumb (Lapeer, Sanilac, Huron, Tuscola counties), most of the Saginaw Bay watershed, mid-Michigan (Gladwin, Clare, Isabella), the northern Lower Peninsula, and large parts of west-central Michigan all sit on iron-rich glacial-drift and limestone-aquifer water. If you are running a route that crosses out of the GLWA service area, you need the phosphoric or oxalic protocol in your truck. If you are a homeowner who recently moved from the Detroit suburbs to a country house with a well, you need a softener, and you need to verify that the softener has iron-rated resin specifically.
I am going to run through the season-by-season contaminant list because I have not seen this written down in one place anywhere for Michigan, and it is what governs my route planning.
March-April: post-winter salt and slush. Salt aerosol residue on ground-floor glass and aluminum frames. Slush splatter on the lower third of road-facing exposures. Accumulated bug residue from the previous fall that froze in place. Dirty masonry runoff onto exterior glass below windowsill drip edges. This is the heaviest contamination period of the year and the easiest to clean — the volume is high but the protocol is simple.
May: cottonwood and pollen. The cottonwood seed-fluff wave runs through the second half of May and the first week of June. Cottonwood is heavily planted along the Detroit and Rouge river corridors and in most of the southern Michigan riparian zones; the fluff is everywhere. It bonds to wet glass electrostatically — exactly the problem Mara describes for Chicago and it is exactly the same in Detroit. Pre-rinse with a surfactant, rinse aggressively, finish with a squeegee. Often requires a return visit to the same property two to three weeks later for the last of the fluff and the catkin debris around the screens. I bundle this into my spring service for accounts that ask about it; I bill it separately as a return visit for accounts that do not.
June: oak and maple pollen. The hardwood pollen wave is moderate-to-heavy in southern Michigan. Yellow-green pollen films horizontal glass and the upper third of vertical glass on east-facing exposures. Surfactant pre-rinse handles it. The bigger working consideration in June is screen mesh — pollen lodges in screens and discolors the glass behind them within a few weeks unless the screens are cleaned at the same service.
July-August: sprinkler overspray and bug residue. GLWA water leaves a manageable film; outstate well water leaves the iron problem described above. Bug residue (June bugs, mosquitoes that died on glass during the night, midges from the lake shorelines) is the dominant working consideration on shoreline counties. Solvent ladder applies: water and surfactant first, then citrus solvent (D-limonene) on the persistent residue, then squeegee finish. I run D-limonene from May through October on most accounts.
September-October: pre-holiday volume and leaf-litter. The pre-Thanksgiving residential rush is real here. Most of my accounts want a fall cleaning between mid-October and mid-November, before the storm windows go up and before the family arrives. The volume is concentrated and the pricing structure I built reflects that — I run a slightly higher per-stop rate in October and discount the spring stop a little to even out the seasonal revenue.
November: leaf decay, the first salt event, and the last good week. The first salt event is usually in the second or third week of November. The last good outdoor cleaning week is usually the week before Thanksgiving. After that the residential exterior market closes for most operators until April.
December-March: closed residential exterior. See section VII.
The Michigan residential exterior market closes for four months a year. This is the single biggest economic fact about running a window cleaning business in this state. Operators who do not plan for it run out of cash by late January in their first or second year. Operators who do plan for it use the window for the back-shop work that you cannot do in season.
Here is what I do during the closed-residential period:
Commercial interior work. A handful of commercial accounts — the Birmingham retail strip I service, the Royal Oak office building I have run for six years, a couple of restaurants — run year-round on a monthly interior schedule. Interior work is unaffected by weather. Commercial revenue during the closed-residential months keeps the lights on.
The spring schedule build-out. I spend roughly the second half of January and most of February calling every residential account on my list to confirm their spring service date. I push everyone toward an actual appointment rather than the vague "call me in April" arrangement that some cleaners default to. By the end of February I have approximately ninety percent of my April-May residential calendar booked. This is the single most useful thing I do all year and most independent cleaners I know do not do it systematically.
Equipment maintenance and replacement. The truck gets the annual service in January. The squeegee rubber is replaced before the spring start. The pure-water filtration system gets new resin and a deep clean. The brushes get replaced. The hose fittings get checked for the salt corrosion described above. None of this is glamorous; all of it is what keeps you working in March when the season opens.
Continuing education and writing. I do most of my writing for Window Washing Guide between January and March because that is when I have time to think about the work rather than do it. The pricing piece you may have read on this site was drafted in February of 2023. The pressure-washing-aftermath piece was January 2024. This article was January 2025. The pattern is intentional.
A real vacation. I take two weeks in February every year and go somewhere south. So does my nephew, since he started doing the route with me. The trade is hard on the body in the summer and the recovery time matters. I am pro-recovery the way some of my colleagues are pro-overtime. Both can be defensible business strategies; mine is the one I picked.
The closed winter market is not a problem you solve. It is a structural feature of the Michigan business that you build the rest of your operation around. The cleaners I know who tried to run residential exterior through December and January (chasing the warm weeks, doing partial work in the freeze-thaw windows) burned out by year three and were out of the trade by year five. The cleaners who shut down residential cleanly and ran commercial and back-shop work through the winter are still in business and not particularly stressed about it.
Some honest notes on the state of the trade in Michigan, from where I sit eleven years in.
The independent operator market is healthy. There are more one-truck and two-truck residential operators in the Detroit suburbs in 2026 than there were in 2015, by my informal count, and the pricing has moved up — the standard per-pane number in Birmingham and Bloomfield Hills is now somewhere between $5.50 and $8.00 for residential service, up from the $3.50-$5.00 range Frank was charging in 2014. The pricing increase is real and the customer base has accepted it. I think the trade had been chronically underpriced in this metro for thirty years and the correction is finally happening.
The corporate franchise market is also growing — Window Genie, Squeegee Squad, Fish — and the per-pane pricing at those operators tends to run higher than the independent market. I have no problem with this. The franchise operators serve a customer who wants the predictability of a corporate brand and is willing to pay for it. I serve a customer who wants the same person to clean their windows for ten years in a row and is willing to pay for that. The two customer types are real and distinct and there is room for both.
The labor question is the hardest one. Reliable seasonal help is genuinely difficult to find in Michigan. The construction trades, the auto suppliers, and the warehousing wages have all increased faster than the window-cleaning per-hour rates can support, and the workers who used to do residential window cleaning as a summer job for college tuition are working at Amazon FCs and Stellantis suppliers instead. My nephew is the exception, and I am paying him well, and I am aware that the only reason I have reliable Saturday help is that he is family. The independent operators who are scaling beyond one or two trucks are struggling with crew retention and most of them are talking openly about it.
The replacement-window wave continues. Most of the post-WWII original wood sash in the Detroit suburbs has been replaced with vinyl- or aluminum-frame double-pane units at this point, and the replacement work moved through the suburbs in a wave from the late 1990s into the early 2010s. The houses that have been replacement-glazed are easier to clean — fewer broken sash cords, no glazing-putty failure, generally squarer geometry. The pre-1945 houses in Birmingham, Indian Village, Boston-Edison, and Grosse Pointe still carry original wood sash and they are the more interesting work technically. They are also the houses where the homeowners are most invested in keeping the original glass, which means they value the cleaning service more, which means they pay better. There is a clear correlation between the age of the house and the per-pane rate I can charge — and the older houses are not the loss they would be in a market with less appreciation for historic preservation.
What I would tell a cleaner moving to Michigan from out of state: the water is easy, the salt is the seasonal driver, the auto-industry corridors carry a denser grime than the trade press recognizes, the outstate well work requires an iron protocol you may not already have, and the winter is closed. Build your business around those four facts and you will be fine. The customer base is here, the pricing has moved into a reasonable range, and the housing stock — both the old pre-war and the new replacement-glazed — supports a sustainable independent residential practice. I have been doing it for eleven years and I am not planning to do anything else.
What I would tell a homeowner reading this: the windows on your house in Michigan look the way they do for specific, knowable reasons. The salt and the road-corridor grime and the cottonwood and the well-water iron are not abstract problems. A good local cleaner — independent or franchise — will recognize what they are looking at and will price accordingly. If your cleaner is quoting a flat per-pane rate without asking about your road-frontage situation, your well versus municipal water, and your sprinkler overspray history, you are working with someone who is leaving information on the table that would have produced a better service for you. Ask the questions. Listen to the answers. The window cleaning trade in Michigan is, in 2026, in better shape than I have seen it in a long time, and the homeowner who pays attention to what a good cleaner is telling them gets the benefit of that.
Detroit and most of the metro suburbs draw from GLWA, which pulls from Lake Huron via the Belle Isle and Lake Huron intakes and from the Detroit River at the Springwells plant. Hardness runs moderate at around 110 mg/L. The housing stock and the salt are the working problems here, not the water.
Grand Rapids pulls from Lake Michigan via a thirty-mile intake at Port Sheldon. Hardness runs moderate at around 125 mg/L. The west Michigan winters are milder than the east side of the state but the lake-effect snow band on the far western edge of the metro does heavy salt-aerosol work.
Warren is on GLWA water through the Warren Department of Public Works. Same hardness profile as Detroit. The post-WWII tract housing stock is the dominant building type — aluminum-frame replacement windows installed during the 1990s-2010s replacement wave are the substrate most cleaners encounter here.
Sterling Heights mirrors Warren on water — GLWA supply, moderate hardness, post-WWII residential stock. The route economics in this corridor (Hall Road to Twelve Mile, Van Dyke to Mound) are the densest in the Detroit suburbs.
Ann Arbor blends Huron River surface water with city wells. The water runs distinctly harder than the Detroit metro at around 200 mg/L. The pre-1945 residential stock around the university and the high concentration of academic-faculty wood-sash housing are the working considerations.
Lansing draws from Saginaw Formation groundwater wells. Hardness runs hard at around 220 mg/L. The state capital and the GM Lansing assembly plant produce a different residential market than the Detroit suburbs — more institutional commercial work, more state-employee residential.
Each city page carries its own water profile, neighborhood breakdown, cost range, and city-specific operating notes.
| CONTAMINANT | SEASON | SEVERITY |
|---|---|---|
| Road salt aerosol and slush splatter | Dec-Mar | severe |
| MDOT is one of the heaviest salt-using transportation departments in the country. Salt aerosol from the roadways deposits on ground-floor glass within a quarter-mile of any plowed road and corrodes aluminum and steel sash hardware over time. Slush splatter from passing traffic coats the lower third of ground-floor glass on every house within thirty feet of a curb. The post-winter call is the entire residential spring season here. | ||
| Auto-industry particulate (brake dust, tire-road wear) | year-round | moderate |
| The Woodward, Telegraph, M-59, and I-696 corridors accumulate a distinctive black-brown film from brake dust, tire wear, and engine particulate that is heavier in the Detroit metro than in most other US metros at the same traffic volumes. The film is particularly visible on white-trim window frames and on ground-floor commercial glass along the major surface arteries. | ||
| Cottonwood seed fluff | May-Jun | high |
| Eastern cottonwood is heavily planted across the state, especially along the Detroit and Rouge river corridors and the riparian zones of southern Michigan. The seed-fluff wave in late May and early June bonds to wet glass with the same static-cling problem Mara describes for Chicago. Requires a surfactant pre-rinse and often a return visit two to three weeks later. | ||
| Outstate iron staining | year-round (well households) | high |
| Well-water households on the limestone-belt aquifers carry elevated iron content. Sprinkler overspray and hose-down work deposits an orange-rust tint on lower-third glass that citric acid alone does not clear. Requires a phosphoric or oxalic pass for full removal, applied carefully to avoid masonry etching. Concentrated in the thumb, mid-Michigan, and the northern Lower Peninsula. | ||
| Black mold around frames | year-round (peaks winter-spring) | moderate |
| The freeze-thaw cycle combined with high indoor humidity produces black mold growth on the interior glazing of failed-seal IGUs and on the lower frame of double-hung wood sashes throughout the state. The Detroit metro housing stock with original 1950s-1970s aluminum-frame storm windows is the worst offender — the storm window condenses interior moisture and feeds the mold. | ||
| Great Lakes shoreline ice-fog deposition | Nov-Feb | mild |
| Shoreline counties (Macomb, Ottawa, Berrien, Charlevoix) see ice-fog deposition during cold-water-warm-air events that crystallizes a thin frost layer on exterior glass and screens. Clears with above-freezing temperatures but the cumulative effect on screen mesh and gasket flexibility is meaningful over a decade. | ||
April through May is the residential peak. The post-winter salt-and-grime call drives volume in the first three weeks of April; the cottonwood wave runs through late May and into June.
June through August is steady residential. Humidity is the working consideration on east-facing exposures; route economics favor early-morning starts. The shoreline counties pick up vacation-rental work in this window.
September through November is the second peak. Pre-holiday cleaning drives October and November. The leaf-litter pass runs through October on the heavily wooded routes.
December through March is largely commercial. Residential exterior work pauses for the hard-freeze season — the longest residential pause of any state outside Minnesota and Wisconsin. The best operators use this window for back-shop work, equipment maintenance, and the spring schedule build-out.
Land-adjacent states each get their own water-and-window profile. If you're working a regional route or moving across the border, these are the natural next reads.
Municipal water in Michigan typically runs 90–420 mg/L (CaCO₃), which is in the moderate range typical for most US markets. Hardness varies by city and source; check the city-by-city breakdown below or use our ZIP-code hard-water tool for a closer reading.
In Michigan, the working operator's calendar typically favors fall — september through november is the second peak. pre-holiday cleaning drives october and november. the leaf-litter pass runs through october on the heavily wooded routes. For a full seasonal breakdown, see the cleaning calendar section on this page.
Residential window cleaning in Michigan typically runs $8–18 per pane or $200–500 for a standard single-family house exterior, depending on metro pricing, story height, screen condition, and frame type. Use our cost estimator for a calibrated quote for your home.
