"The 2 workers went above and beyond. Made a badly stained and mildewed awning look brand new. Keith also fixed 2 door screens that had been pushed out by my grandchildren and my dog by accident. I did not ask he just did it. And Mary came back in the house to look into a smudge in a window that I look out of all the time. No attitude, just happy to take care of it. Very pleasant to have around. Had no qualms over having them in my house. Ron, you have a great crew."

Window Cleaning FAQs, answered by experts

The simplest way to clean stained glass windows is by using warm distilled water and a damp cloth. Distilled water won’t corrode the stained glass or leave residue behind. Avoid using cleaners with alcohol or ammonia. However, you should only clean when necessary. Stained glass windows are fragile, and excessive cleaning could cause fading, weakening of the solder, or other damage.

Yes, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.

Yes, with special treatments that help repel water spots and grime build-up.

Soot can be harder to remove compared to other types of stains given its acidic nature. It can also cause underlying paint to peel off during the cleaning process. If your soot issue is a result of smoke damage, it’s recommended you call a pro to help remove it versus doing it yourself.

Window cleaning costs around $220, on average, but you could pay anywhere from $150 to $300 or more, depending on the number of windows, how accessible they are, and the type of windows. Some professional window cleaners charge on a per-window basis at around $10 per window, while others provide a single price for your entire home. Either way, more windows will mean higher cleaning costs. Picture windows tend to be the most affordable because they don’t require cleaning of internal components, while double-hung windows and skylights increase your price because they’re more complicated to clean and less accessible.
