What Homeowners Are Saying

Had the outside and inside windows of my house cleaned last week and the glass became so crystal clear it was literally as if the outside was in. Still looks good. No smudges, no streaks! Sills and tracks were cleaned from dirt and debris as well. Greg was thorough and showed great attention to detail. He was careful not to disturb my ground plantings as he worked on the windows above.

Truly recommend your using SUNSHINE WINDOW WORKS to get that crystal clear finish on your windows.

The first picture shows my very clean window from INSIDE my house. For comparison, the second picture is the same view but from outside. Crystal clear inside to out. Third picture shows how clean the tracks became on this 30+ year-old home.

Greg did an amazing job on my windows. He was timely, professional, and detail oriented with everything from the screens to the glass. It's like a whole new world when I look outside now. So much brighter! Highly recommend Sunshine Window Works.

Greg did an amazing job on our windows! I didn't realize how much of a difference clean windows could make until he was done. He cleaned both the inside and outside, and everything looks crystal clear.

You can tell he really takes pride in his work. He was incredibly thorough, paid attention to all the little details, and made sure everything was spotless before he left. He was also friendly, professional, and easy to work with.

If you're looking for someone to clean your windows, I highly recommend Greg. We'll definitely be calling him again!

Highly recommend Greg at Sunshine. He cleaned all four units in our townhome complex, interior and exterior and screens, and did an excellent job. He was professional, prompt, and communicated well throughout the process. The windows look fantastic. Would definitely hire him again.
