- EOElsie O'dwyerAug 8, 20265.0The crew showed up on time and went right to work. They did an excellent job inside and outside. They were very careful and aware of the job they were doing. A pleasure to work with.

- JCJames ClemmerAug 3, 20265.0My home windows have not been cleaned for a long time so they really needed cleaned. I also have a shop with windows which have not been cleaned in about 10+ years. They were very dirty. The Zenith crew did a thorough cleaning of all windows and screens. I’m amazed with the quality of their cleaning and rechecking for streaks or dirt before they finished and left the premises. I highly recommend Zenith Window Cleaning as a company of integrity and thoroughness.
- AYAlicia YohoJul 29, 20265.0We had a fantastic experience with Zenith. They provided a quote quickly, arrived promptly and did a great job. We had a renovation last year, and the windows, screens and tracks were filthy after not being cleaned for a while. It was nice that was all included in the price, which I found to be reasonable. They even put forth extra effort to get some stubborn hard water buildup off some of the windows. We’ll definitely be using them again in the future.
- MKMary Ann KetelhutJul 24, 20265.0Zenith Window Cleaning just completed washing my windows for the fourth year in a row. I cannot believe the transformation from how they look before and the amazing clear result afterwards. The ionized water system leaves the glass spotless! Hunter and Karl were such a pleasure to work with. Both were extremely friendly, professional, and respectful of the workspace. I look forward to seeing you again next year.
