What should you pay to get your windows cleaned? In the Chicago area, the window washing cost for a typical home runs from about $180 to $380 for inside and outside service. However, the final number depends on how many windows you have, how high they sit, and which extras you need. This guide breaks down real 2026 prices, so you can plan your budget and spot a fair quote.
What Affects Window Washing Cost
Every home is different, so most companies price by the job instead of by the hour. These five factors matter most:
- Number of windows. This is the biggest factor. A ranch home with 12 windows takes far less time than a two-story home with 40.
- Inside and outside, or outside only. Cleaning both sides also nearly doubles the work on each pane.
- Height and access. Glass on the second or third floor needs ladders or poles, so it takes more time and care.
- Condition of the glass. Likewise, hard water spots, paint specks, or dust from a remodel need extra work.
- Extras. Finally, screens, storm windows, skylights, and window wells each add a small fee.

Inside and Outside, or Just Outside?
Outside-only cleaning costs about half as much, so it makes sense for many homes. For example, outdoor glass collects pollen, rain spots, and road dust much faster than the inside does. That is why a popular plan is a full cleaning in spring, followed by an outside-only visit in fall.
On the other hand, homes with kids, pets, or smokers often need the inside done more often. After all, fingerprints and film build up quickly on indoor glass. If you are not sure how often to book, our guide on how often to clean windows professionally can help.
Common Add-Ons and What They Cost
Extras are where quotes tend to differ the most. Below are typical add-on prices from our list:
- Screens: $3 to $5 each
- Storm windows: $4 to $5 each for half size, or $7 to $10 for full size
- Skylights: $15 to $20 each
- French windows: $5 to $8 each, inside and outside
- Window wells: $5 to $30 each
- Cleaning after construction: $4 to $8 per window, inside and outside
Most of these items take extra time because the crew works by hand. For instance, the crew has to remove each screen, wash it, let it dry, and put it back in the right frame. So before you compare two quotes, check that both include the screens.
Why the Cheapest Quote Can Cost You More
A very low price can hide problems. Some crews skip the screens, rush the edges, or leave streaks that show up in the afternoon sun. Others, however, carry no insurance at all. As a result, if a worker falls from a ladder on your property, you could be the one at risk.
Before you hire anyone, ask for proof of insurance and a written estimate. The Illinois Attorney General also shares helpful tips to avoid home repair fraud. Ernest Windows carries full insurance and bonding, and we put every price in writing before we start.
How to Lower Your Window Washing Cost
- Book regular visits. Glass you clean twice a year comes clean faster than glass you ignore for years.
- Bundle your services. Pair your window cleaning with gutter cleaning on the same day, since the crew and ladders are already there.
- Clear the way. Move plants and furniture away from the windows before the crew arrives.
- Mix in outside-only visits. They also keep your curb appeal high for about half the price.
Small steps like these keep your window washing cost low year after year. Also, clean windows let in more daylight, which makes every room feel brighter and larger.
