They did come back to fix the screen but it was one more thing to deal with. For $400 I expected much better. Will not use them again.

We had Sonlight clean three days ago. I was not home during the cleaning. Some of the windows…read morewere not cleaned and there were three carpet stains where the cleaner had put wet screens on the carpet. When Jamisen texted to ask how things were, I was kind but honest. I didn't ask for anything but he offered to fix it the next day at noon. No one showed up so I texted and asked what happened. He said there was a mix up and they would be there tomorrow at 12. I said that was fine but they no showed again. When I texted after the second no show, he said they could be there by 9 am "tomorrow". I really don't know why he thought I would believe someone would actually come but I said no thank you. I did a little research and it looks like Sonlight is heading more towards commercial business and it would seem the residential business is taking a back seat. I would look for a window cleaner whose primary business is residential.

After years of great gutter cleaning and a first time with window exteriors in 2022, we opted to do it all this year. I no longer can the interiors myself as vision and health challenged and I am so glad it was done so well today. If you read my previous review, you can see how challenging our home is to service. We have removed some of the trees which has helped immensely with the debris in our gutters and and cleared more for fire and wind safety too. Benefits the gutter situation also. I will definitely use Glass Gecko again. Every member of their staff has always been efficient, courteous and safe. And we love supporting a homegrown Boulder business.

The windows look great, but the screens were still dirty after their cleaning. In my opinion, dirty screens sort of cancel out the clean windows. Arrian was not with the two men who worked here.
