Best window cleaning service. You want your windows squeaky clean , best place for your services .
As a longtime customer over 10 years both of my Chicago location windows were really filthy so we called the company and they said that they will not service us anymore going forward. It’s been over a month since they came to my businesses and the guy cleaning the windows never even told us about this so we had no back up plan Service do not use them!!
Seriously the best window washers out there! My windows never looked this good and I’m so happy with the service. The owner is awesome and very engaged! I recommend. This company over anyone and I’m very very picky.

The communication throughout the entire process was amazing. Now for the window cleaning… The employees were very prompt in arriving when promised. They were very careful in the interior making sure that nothing around the windows got damaged. After completion they noticed that the exterior windows had a small amount of streaking, so they went back outside to cleanup any spot that wasn’t perfect. I give them a 10 out of 10.
Superb experience, far exceeding our expectations, on an extremely difficult job! We have a five story condo building with an odd shape and many hard to reach windows. The job required access into owner units and many non traditional aspects. Other window washers had previously failed to complete the job satisfactorily. After hearing our past history with window washers, Rich was determined to give us a positive experience. He met with us onsite 2 times before the scheduled date to plan for all contingencies and to troubleshoot issues we have had in the past. He supervised the job for 2 days and did not leave until the last window was cleaned. The job went off without a hitch, and the windows were spotless! A fabulous experience far exceeding our expectations! Highly recommend, especially if you have a difficult job that requires supervision and attention to detail.
After speaking with the sales team and explaining the work I was looking to have done, they had me take photos and outline the work (two stories of a couple up). After following up for 2 days I got an email back saying they won’t quote the work and we’re only interested if they could quote all units in the building. Wouldn’t have been so frustrating if they just told me from the start.
So sorry for the confusion, Elliott. Feel free to reach out, as we'd be happy to resolve this.
Someone from upper management has reached out to rectify the problem. Original employee no longer works with the company that did not fix the issue and I have been reimburse for services in question. ----------------------------------------------------------------------------------------------------------------------
