- MLMargaret Lackner3 days ago5.0Spectacular job. Including all the small stuff and spiders removed. Friendly, efficient, showed up on time and on the date made 6 months prior. Even offered to come back if it rained. Only hope they don’t get so popular that they can’t keep coming back
- LALori AllenOct 7, 20265.0Phenomenal service from start to finish with Tom, Karl and Levi. I connected with Zenith because when I pulled into my neighborhood one day, I did a double take at my neighbor’s windows which were literally sparkling. I noticed the Zenith truck and went to their website immediately. Tom’s communication was perfect; clear, friendly and incredible response time. Karl and Levi were wonderful. They came to the home and were friendly, thorough, and clear about the process. I could not be happier. My windows look absolutely stunning!!! I knew they in rough shape—didn’t realize how bad until after they were finished. Glistening! Thank you! Before an after photos included!
- CPCarol ParkerOct 6, 20265.0I would not use anyone else for these services. Zenith has been cleaning my windows since I owned my home. This year, we added gutter cleaning. Levi and Karl were great. Both respectful and conscientious. And you'd be amazed at how light and bright the cleaned windows are.
- DCDebbie CurtisOct 5, 20265.0Very impressive, our windows look amazing. We have a lot of windows, they cleaned the window seals, and all the windows and doors inside, and out. He even cleaned the class doors in the office. Definitely will use again! Highly recommend Thanks so much
- KPkp poirySep 29, 20265.0Good communication. I have been having lots of work done and contractors texting they plan to be there and ghost you. I was beginning to think it was a thing. Not here. Excellent communication and they actually came an hour early. The work is also 5 stars. Do yourself a favor and see how amazing it feels to look at the world outside through crystal clear windows You will be happy you did it.
