A practical window cleaning plan for Chicago apartment buildings, condos, and walk-ups. Learn how to schedule crews, handle high floors safely, and keep windows sparkling despite lake-effect weather.
Windows are the first thing prospective tenants notice when they walk up to a building, and they're one of the first things existing residents complain about when neglected. In Chicago, our mix of lake-effect weather, urban soot, and salt-spray from winter streets puts windows through a lot. By late April, most multi-unit buildings in Lincoln Park, Lakeview, and Rogers Park show a visible gray haze on the exterior glass — a combination of winter road salt, diesel exhaust, pollen, and the mineral-heavy rain blown in off Lake Michigan.\n\nFor property managers and HOA boards, clean windows aren't just cosmetic. They signal that the building is well cared for, which influences lease renewals, resale values, and tenant satisfaction. A greystone in Logan Square with filmy windows reads as tired — even if the rest of the building is in perfect shape.
The right cadence depends on building type, location, and how much exposure windows get to wind and traffic. Here's a practical baseline we use across our Chicago portfolio:\n\nFor most walk-ups and 2-flats in quieter residential pockets of Andersonville or Ravenswood, two exterior cleanings a year — one in spring and one in fall — will keep windows looking sharp. For mid-rise buildings along busy corridors like Ashland, Western, or Lake Shore Drive, plan on three or four exterior cleanings annually. High-rises with floor-to-ceiling glass need quarterly service at minimum.\n\nInterior window cleaning in common areas (lobbies, hallways, fitness rooms) should happen monthly or bi-monthly. In-unit interior cleaning is typically the tenant's responsibility, but offering a paid semi-annual service can be a nice amenity in higher-end buildings in Lincoln Park or Old Town.
Chicago's weather creates narrow windows (no pun intended) for exterior work. Spring cleaning is best scheduled between mid-April and late May, after the last hard freeze and before the first heavy pollen waves from trees and grasses. If you clean too early, one more cold snap or dust storm off the prairie will leave streaks behind within days.\n\nSummer cleanings should avoid the hottest afternoons — cleaning solution evaporates before it can be wiped, leaving streaks. Early morning work between 7 a.m. and 11 a.m. is ideal. Fall cleanings should wrap up by late October before overnight temperatures drop below 40°F, which slows drying and can etch hard-water spots into glass.\n\nNever schedule exterior window cleaning the day before or after a major storm. Always build in a weather buffer — a two-day window around the appointment — and use vendors who will rebook without a charge if conditions deteriorate.
