Searching for window washing in Chicago brings up dozens of companies, and they all promise spotless glass. However, the difference between a five-star experience and a frustrating one usually comes down to a few details most homeowners never think to check. After 22+ years of cleaning windows across Chicagoland, we know exactly what separates the pros from the rest.
Here are the six things we recommend you verify before letting anyone near your windows — whether you hire us or someone else.
Window Washing in Chicago: Why Your Choice Matters
Window cleaning looks simple from the ground. In reality, it involves ladder work at height, delicate glass, and access to your home. Consequently, the wrong hire can mean scratched panes, damaged screens, or a worker injured on your property with no insurance to cover it. The right hire, on the other hand, delivers streak-free glass, protected trim, and total peace of mind.
1. Insured and Bonded Window Washers
This is non-negotiable. Professional window washers in Chicago should be fully insured and bonded — and happy to prove it. If a technician falls from a ladder or a window cracks, insurance protects you from liability. Ernest Windows has been fully insured and bonded since 2003, and we provide documentation on request. If a company hesitates when you ask, keep looking.
2. Real Chicago Window Cleaning Experience
Chicago is hard on windows. Freeze-thaw cycles stress seals, spring pollen coats screens, and our mineral-rich water leaves stubborn hard water stains. Moreover, many local homes still use storm windows, which take extra time and know-how to clean properly. A window cleaning crew that works in the Chicago area every day will spot these issues early — and clean around them without causing damage.
3. Transparent Pricing You Can Check Yourself
Reputable companies publish their prices. Vague “call for a quote” answers often lead to surprise charges once the crew is already on your driveway. Therefore, we list every rate on our price guide page, where you can also use our instant estimate calculator to price your exact window count in seconds — before you ever pick up the phone.
4. Professional Window Cleaning Tools and Process
Ask what the service includes. Quality window washing covers the glass, frames, sills, tracks, and screens — not just a quick outside rinse. Our technicians use professional squeegees, soft cloths, and eco-friendly solutions instead of harsh chemicals. As a result, you get streak-free glass and healthier light in every room. In fact, clean windows carry real health benefits for your home, from better mood to fewer allergens.
5. Window Washing Reviews and an A+ Reputation
Third-party reviews tell you what a company is really like. Check Google reviews from neighbors in your suburb, and look the business up with the Better Business Bureau. Ernest Windows holds a 5.0 Google rating and a BBB A+ rating — built one clean window at a time across two decades of window washing in Chicago and its suburbs.
6. A Written Satisfaction Guarantee
Finally, ask what happens if you are not happy with the result. A confident window cleaning company stands behind its work. Our guarantee is simple: if anything is not right, call us within 7 days and we will re-do the job to your satisfaction — free of charge.
