Jonesboro glass takes agricultural field dust in concentrated seasonal bursts, plus fine wind-blown loess that works its way into frames and seals.
Jonesboro's City Water and Light pumps groundwater and publishes no hardness figure, since Arkansas reports carry no table for it. The farm calendar matters more than the tap: field dust arrives in bursts, fine wind-blown loess works into frames and seals, and a fringe property cleaned the week before harvest is dirty again within days. Aim for June to September, when a single-story exterior runs $200 to $380.
No figure is published, and this is the city where that absence actually costs something. Arkansas's surface-supplied cities can reasonably be expected to run soft, but groundwater takes its character from the aquifer and cannot be assumed to follow suit — so the honest answer here is that the mineral content is unknown, not that it is low. Anyone working a large or recurring account in this city is better served by a local hardness test than by any published number, and the dust problem is in any case the larger one.

Agriculture sets the calendar and it is spiky rather than seasonal. Land preparation in spring and harvest through autumn put heavy dust into the air over short windows, and there is little point servicing fringe properties in the middle of one. Ridge properties run on a canopy cycle instead, steady through the growing season and heaviest in leaf fall. Summer humidity keeps mildew working on shaded elevations throughout, and ice closes the ridge streets before it closes anywhere else.
ARKANSAS SEASON BY SEASON →Jonesboro runs a municipally owned utility drawing groundwater rather than surface water, and no hardness figure is published — the Arkansas reporting format has no aesthetic table at all, which is a sharper gap for a well-supplied city than for a reservoir one. Geography does the rest: Crowley's Ridge puts wooded, shaded slopes on one side of the city and dead-flat rice and soybean ground on the other, producing canopy film in one half of the market and concentrated field dust in the other.
Jonesboro's water is municipally owned and comes from wells rather than from a reservoir, which puts it in a different category from the surface-supplied cities across the rest of the state.
No hardness figure appears in the state's reporting format, which carries no secondary or aesthetic table at all — so for a groundwater city, where hardness would ordinarily be the most relevant aesthetic parameter, the report is silent by design rather than by choice.
That silence matters more here than it would elsewhere. Surface-supplied Arkansas cities can reasonably be assumed to run soft; a well-supplied city cannot, because groundwater picks up whatever the aquifer material gives it, and the answer is genuinely unknown without a local test.
Geography is the city's defining feature and it is unusual. Crowley's Ridge rises out of the Mississippi alluvial plain as a narrow band of wind-deposited loess, so Jonesboro has wooded slopes on one side and dead-flat farmland on the other within a few miles.
That split produces two different soiling regimes in one market. Ridge properties sit under trees and deal with organic film and canopy drip; fringe properties sit beside open fields and deal with agricultural dust.
Field dust does not arrive gradually. Land preparation, harvest and burning put large quantities of fine particulate into the air over a handful of days, and glass that was clean on Monday can be unusable by Friday during those windows.
Loess itself is very fine, wind-mobile silt, and it is the reason dust here behaves differently from the coarser grit of a construction market — it works into frame channels and seals and it is abrasive enough that dry-wiping marks glass.
The university is the largest single client opportunity in the region and it runs on a semester calendar, with the realistic working windows falling in breaks rather than in good weather.
Delta humidity through the summer keeps shaded elevations damp, so mildew on frames and in glazing channels is a routine complaint rather than an occasional one.
Winter ice storms rather than snow are the disruption that matters, and on the ridge streets they close access before they close the flat parts of town.
Timing relative to the agricultural calendar is the input most often mispriced, because a fringe property serviced the week before harvest is effectively wasted work and the customer blames the cleaner. Ridge properties price on access, slope and canopy. The university and the Highland Drive strip price on volume and predictable scheduling and are where the reliable revenue sits. Nothing in the price relates to water treatment, because nobody knows what the water is.
Ordinary residential glass is a reasonable homeowner job in the quiet weeks between dust events. The single most important habit here is never to dry-wipe — loess is fine, angular and abrasive, and wiping it dry will mark glass permanently, which is a more common cause of damage in this market than any chemical. Flood the surface first, always. University and commercial work is a scheduling business rather than a technical one and sits outside domestic practice.

Jonesboro's fire code makes it unlawful to open, turn on or carry away water from a public hydrant for private use, or to sprinkle streets or private property from one, without written authority from City Water and Light first. A crew filling a pure-water tank has to get that letter or fill from the client's own tap.

Jonesboro's stormwater code bans illegal discharges: nothing that would cause or add to a water quality violation, pollutants included, may go into the city stormwater management system.

Jonesboro's zoning code creates no historic district or historic overlay: its overlays are for limited uses, village residential areas and the municipal airport. With no local commission reviewing exterior work, replacing or repairing glass on an older Jonesboro building follows the ordinary building-permit route.

Loblolly, shortleaf, and Arkansas pine produce the dominant statewide spring contaminant. Heavier pulse than the deciduous tree-pollen wave that defines the Northeast. Wet-only handling. No scraping, no dry-brushing. Same pattern Elly Giordano documents for Alabama and Mississippi.
Statewide tornado activity heavy. Wind-driven debris pattern, hail-impact residue, occasional structural-residue from damaged adjacent properties. Recurring post-event cleaning surge through the spring season.
Mississippi Embayment alluvial-aquifer water with sub-micron suspended-particulate fraction. Iron content moderate-to-high on some distribution-system segments. Extended citric pre-treatment (3-5 minutes) plus citric-rinse finish required on most Delta-corridor stock.

Residential window cleaning in Jonesboro typically runs $7–12 per pane or $200–380 for a standard single-story exterior. Timing relative to the agricultural calendar is the input most often mispriced, because a fringe property serviced the week before harvest is effectively wasted work and the customer blames the cleaner.
Jonesboro's drier, frost-free months are June to September, by NOAA's 1991–2020 normals for the Jonesboro Municipal Airport station, where May brings the most rain. The calendar on this page marks June (after the March 30 bloom and after smoke season). Frost nights usually run from November 9 to March 23. Normal highs reach 90°F in June to August.
City Water and Light publishes neither hardness nor dissolved solids, so rinse one pane and let it dry in sun; a white ring means switch to pure water. Treatment starts with packed-tower aeration with an orthophosphate inhibitor for iron, manganese, pH adjustment for corrosion control and pre.
