Window Washing in Fort Worth
Fort Worth water runs 76.5 to 183 mg/L hard, sprinkler overspray leaves that on the glass, and pecan pollen and catkin debris pile up on top of it.
Fort Worth's water moves between moderately hard and hard depending on which reservoirs are carrying the system, so expect spotting on dark glass in sun as a baseline, worse where sprinklers reach. Pecan pollen and catkins pile up on sills each spring; wash in April, from July to September, or in November. Route density splits prices between the efficient northern build-out and Westover Hills and the older enclaves; a single-story exterior runs $300 to $510.
What the water means for the glass
Five to ten grains covers most of the useful range on its own, which is the point: Fort Worth's supply is moderately hard some of the time and hard the rest, depending on which of seven reservoirs is carrying the system. Expect visible spotting on dark glass in sun as the default, and expect it to be noticeably worse in some years than others for reasons nothing to do with the work.

|---|---|
| pH | 7.8–8.5 |
| Alkalinity | 73.3–149 mg/L as CaCO₃ |
| Sodium | 22.9–31.5 mg/L |
| Chloride | 18.1–35.2 mg/L |
| Total dissolved solids | 156–289 mg/L |

| Source and treatment | Seven raw-water sources bought from the Tarrant Regional Water District: Lake Worth, Eagle Mountain Lake, Lake Bridgeport, Richland Chambers Reservoir, Cedar Creek Reservoir, Lake Benbrook and the Clear Fork of the Trinity River. TCEQ rates the risk to those sources as high for most contaminants. · Conventional surface-water treatment meeting the disinfection-byproduct-precursor treatment technique, with chlorine dosed alongside ammonia so the residual carried through the distribution system is a chloramine.

When a wash holds
What sets the cleaning clock
Pollen sets the spring reset, with the pecan catkin drop overlaying the oak wave in March and lingering stickily afterwards. Through the rest of the year, irrigation exposure on west-facing elevations drives frequency far more than anything seasonal does, and the dust that arrives on north winds is worst in the dry months.
TEXAS SEASON BY SEASON →What's specific to Fort Worth
Fort Worth publishes total hardness as a range every year, and the range is wide: 76.5 to 175 ppm, 5 to 10 grains, in the most recent report, against 107 to 183 and 101 to 133 in earlier years. Seven surface sources feed the system, which is why. Operating reality mirrors Dallas but with more pecan exposure and a less dense commercial concentration outside the core.
The city reports hardness as a span rather than a point and publishes it in both units: 76.5 to 175 ppm, or 5 to 10 grains per gallon, in the most recent report. Earlier years give 107 to 183 (6 to 11 grains), 126 to 164 and 101 to 133. The low end is moderately hard and the high end is hard, and both are real depending on which source is dominant.
That spread has a structural cause: Fort Worth draws on seven surface supplies — Lake Worth, Eagle Mountain Lake, Lake Bridgeport, Richland Chambers Reservoir, Cedar Creek Reservoir, Lake Benbrook and the Clear Fork Trinity River — purchased through the Tarrant Regional Water District. Different reservoirs carry different mineral loads and the blend shifts with availability.
The rest of the published chemistry moves with it: calcium 23.6 to 61.5 ppm, magnesium 4.26 to 8.58, alkalinity 73.3 to 149, sodium 22.9 to 31.5, sulfate 22.3 to 49.7, conductivity 273 to 479 and total dissolved solids 156 to 289. Nearly every parameter roughly doubles across the range, which is the signature of a genuinely variable blend rather than a measurement artefact.
Fort Worth achieves corrosion control through pH adjustment rather than a phosphate inhibitor, and publishes finished pH at 7.8 to 8.5. That is mildly alkaline and worth accounting for when mixing an alkaline cleaner, though nothing like the extremes in the western systems.
The state's own source-water assessment classifies the risk to Fort Worth's raw supplies as high for most contaminants, which drives active treatment and is the honest context for a city whose water nonetheless tests clean.
Pecan pollen and catkin debris in March overlays the regional oak wave, and east-side neighbourhoods under mature pecans catch a heavy sticky film that behaves more like honeydew than pollen — it needs a surfactant and a dwell rather than pressure.
The western edge of the metroplex catches Hill Country limestone dust on north winds. Combined with irrigation overspray at the hard end of the published range, west-facing glass is where aftercare earns its keep in this city.
Sundance Square gives downtown a tourist-corridor storefront book judged on appearance daily, while Alliance and north Fort Worth are post-2000 master-planned build-out with uniform dual-pane glazing and the best route density in the market.

The city, by neighborhood
What window cleaning costs in Fort Worth
Route density splits this market cleanly: Alliance and the northern master-planned build-out are uniform and efficient, while Westover Hills and the older enclaves are large, individual and slow. Downtown's Sundance Square frontage prices on appearance and short intervals. Irrigation-heavy west-side work carries an aftercare component the east side does not.
Doing it yourself
At the soft end of the range a careful homeowner gets a clean result on accessible suburban glazing; at the hard end the same method spots, and nothing about the house has changed. The pecan film is the technical trap — it is sugary rather than mineral, so people scrub it and spread it. Overspray on west elevations is the one that causes permanent damage if it runs unchecked.

Fort Worth's year-round rules hold sprinklers to two assigned days a week, never on Mondays or between 10 a.m. and 6 p.m., while watering with a hand-held hose is allowed at any time. Water waste through runoff is banned all year, so keep rinse water from running into the street.

Fort Worth requires a city permit for mobile commercial cosmetic cleaning, defined as power washing, steam cleaning or other mobile cleaning of vehicles or exterior surfaces for pay, and permitted rigs display their permit number and sticker. Wash water may go to a storm drain only when it fits one of the city's listed exemptions, with the inlet screened to catch debris.

In Fort Worth, any exterior change to a historic property, windows included, needs a Certificate of Appropriateness before permits are issued or work starts. Applications go in through the city's Accela portal; staff can approve some themselves, and others go to the Historic and Cultural Landmarks Commission.

What actually shows up on Fort Worth glass
Heaviest in San Antonio, whose published figure is the extreme end, and on hill-country well systems. Lower-third of patio doors and ground-floor windows accumulate visible mineral cement within a single summer.
Pecan trees, common throughout central and east Texas, release pollen and shed catkin debris in late spring. Catkins lodge in window screens and against glazing beads, decomposing into a sticky residue if not cleared.
