Window Cleaning in Illinois

No — rain itself is fairly clean; the spots you see after rain come from dirt already sitting on the glass. Pure-water-cleaned windows usually stay clear through rain, which is why professional rounds run all year. Most round cleaners offer a re-clean if windows genuinely spot within a day or two of the visit — ask about the policy.

Exteriors: every 4-8 weeks on a regular round keeps glass consistently clear; quarterly is the practical minimum in cities or near trees and coasts. Interiors need cleaning 2-4 times a year in most homes. Homes near the sea (salt), busy roads (film) or construction (dust) need shorter cycles.

Demand peaks in spring and before year-end holidays, and those slots book out first. The work itself runs year-round in most climates — pure water works in cold weather down to around freezing, and professionals add glycol or adjust hours in frost. If you want a new regular slot, off-peak (mid-winter, mid-summer) is when good rounds have openings.

For exterior-only cleans, no — most regular rounds run with the customer out, with payment by app or transfer. Unlock side gates and confine pets before the visit. Interior cleans obviously need access; many customers book inside-and-out once or twice a year and exterior-only in between.

Typically $4-$14 per pane, with whole-house jobs averaging $150-$300 for an average home and inside-and-out service at the top of that range. Screens (roughly $1-$5 each) and tracks are common add-ons. Two-story homes price meaningfully higher than single-story.

Usually not by default. Screen cleaning runs about $1-$5 per screen, and storm windows can effectively double the pane count — which is why quotes that skip the question balloon on site. Count your windows, screens and storms before calling and ask for an itemised all-in price.
