The technician (John) did NOT dry the windows he just washed, leaving that chore to us. We consider that a very unfriendly approach to customer service.

Jaques was INCREDIBLE!! Deck pressure washing was so detailed and was also mindful of the paint on the deck. Was very knowledgeable in how to handle every thing. Windows were fabulous. He clean all the windows and screens. Asked me to double check everything before he left in case I wanted touchups on anything but everything was perfect! Thank you!!!

Jaques and Tariq did a great job. They came on time, explained to me what was going to happen and then they went to work. Once they were done, they showed me pictures of the gutter and solar panels, both the before and after pictures. They also let me know about any other problematic spots and provided recommendations when I should treat it. Thank you guys, definitely will use their service again.

Jude did a great job on the exteriors of each window (interior was not an option at this time). He answered questions, clarified procedures and reviewed the sparkling results with me. See you next time Jude.

Johnny Tsunami took my call on getting my roof started on treatment for moss on our home. Whyatt was my technician today. Whyatt was very thoughful with his planning and kept great communication with me while I was at work and on the road. I came home to a clean driveway that I neglected over the years.
It was a very hot evening and Whyatt was up to the challenge. He handled our home singlehandedly till the sun started setting. Needless to say, I'm very pleased with the amount of work put in by Whyatt. He kept me up to date on his status to the very end.
Thank you for your hard work today Whyatt, it is greatly appreciated!

There were some equipment issues and miscommunication but Whyatt was very professional, kept in contact, handled the matter, and got the job done. He was very quick, efficient, and conscientious. The driveway and roof looks great.
