What Customers Say
Absolutely the best window washer I have ever had. He was professional, reliable -showed up on time, was detailed- making sure he got every little bit of dirt off the windows. His price was very reasonable. I will definitely have him come again. I told him to put me in his schedule for next year.. Thank you very much GP Window Clean.

Gil with GP Window came to our lake cabin and did a fantastic job! We were under a time crunch and he snuck us in so our windows looked fantastic for our big family weekend! Everything turned out perfectly! The window were clean and shined bright. Gil is very professional, prompt, and courteous. Highly recommended!

5/5 service. Gil is extremely detail oriented and made our windows spotless! I did not realize how big of a difference it would make to have our windows cleaned like that. He took care of the glass, the screens, and cleaned out the tracks! Would highly recommend anyone looking for service to contact Gil.
