Mt Diablo Window Cleaning

⭐⭐⭐⭐⭐ Gilberto has cleaned my solar panels twice and did an excellent job both times. He is professional, punctual, and very thorough. After each cleaning, I noticed a clear difference in the panels’ appearance and performance. He also installed pigeon proofing around the panels, and the work was done neatly and securely. No more birds nesting underneath! His pricing is very reasonable, especially for the quality of work he provides. I highly recommend Gilberto to anyone looking for reliable solar panel cleaning or pigeon proofing. Great service every time!

Gilberto and the team from Mt Diablo Window Cleaning did an outstanding job today. They were punctual, professional, and paid great attention to detail from start to finish.

Communication was easy, pricing was fair, and the quality exceeded expectations. I highly recommend them to anyone looking for reliable, high-quality window cleaning. Will definitely be using them again!

Mt Diablo Window Cleaning: They were punctual, did a great job cleaning my solar panels. Last year they also installed the protective wire mesh around the solar panels. These have efficiently detered birds/doves. The crew is professional, Reliable, efficient and I got a good fair price. - I'm a customer for life!

Mt. Diablo Window Cleaning was able to come out quickly and offered a very reasonable price. I received six other proposals, and they were by far the most fair. They did a wonderful job, and the service was efficient and professional. It’s disappointing to see how much some companies are price gouging, so I truly appreciated their honesty and quality work. Thank you so much to the Mt. Diablo team!

I’m very pleased with the response and service I received as a “first time” caller for interior and exterior window cleaning in our 2 story house. Explanation and fees for services were clear. Although I had to reschedule my appointment several times to coincide with the installation of the new shutters for our windows staff was very understanding. The person arrived as scheduled to clean the windows. He did a great job. I’m definitely planning to utilize this service again as necessary.
