Our Story

Boulder County windows,
crystal clear

Summit Window Cleaning Co was founded in 2017 by Amanda Reyes, a Boulder local who was finishing her environmental science degree when she spotted a gap in the market. Most window cleaning companies in Boulder County were using harsh chemical solutions and wasteful methods. Amanda wanted to do things differently, so she built Summit from the ground up with eco-friendly products and purified water systems at the core.

The purified water approach matters more than it might sound. Tap water carries dissolved minerals that leave spots and streaks on glass as it dries. Our purified water system removes those minerals before the water ever touches your windows, so the glass dries completely clear with no residue and no wiping required. It is a cleaner result, and it is gentler on your landscaping and home exterior too.

"we had the best experience with ADAM the technician from Sonlight Window Cleaning! What a fine young man with exceptional diligence and care, he made our windows sparkle! He was also very polite and did a very thorough job even in the hardest to reach areas. We have little panes - divided light windows and I have never seen them look so good. I cannot recommend Sonlight any higher. They are the very best."
