See Why Homeowners and Business Owners Rave About Diamond Window Cleaning — Honest Reviews Highlighting Sparkling Windows and Professional Service

In addition to all exterior and interior windows and screens, had them do power washing of all front walkways, driveway, back walkway, porch and hardscape. Also completed our composite deck and washed side wall of home (mold, algae & dirt) & gutters. Team was courteous, meticulous and did an excellent job overall. They replaced anything that had to moved and were careful of existing landscaping. Will definitely use them again. Team of 3 were able to complete all this work in one day.

We have SEVERAL sets of paned french doors in our home as well as TWO toddlers running around with full time jobs of placing their handprints meticulously in each and ever glass surface possible. Jeff and his crew did an AMAZING job erasing their *masterpieces* inside my home. As well as getting all my exterior windows crystal clear. HUGE thanks to them, we will be setting us annual maintenance services.

Diamond Window Cleaning did an amazing job cleaning every window, transom, and mirror in our 3-story home. Very prompt and professional crew. They were even able to remove and clean many painted-on storm windows that I didn’t think were able to be removed.

Our house was built in Fall 2019/Spring 2020, and we still had some finishing touches up until this summer. We decided to have everything professionally cleaned when finally finished, and we are very pleased with the results! :)
