Mashath was wonderful!! He returned my call immediately. He was professional and helpful on the phone. He cam to give us an appraisal and his price was better than most. He was punctual, explained everything, his work was exactly what he promised!! He was thorough, professional and cleaned up after his work. Several neighbors have reached out and commented that it looks like we have a new roof. We also had him clean our gutters and he repaired several things that we had no idea were a problem. I would highly recommend him to anyone!!

Our experience with AI Power Wash was terrific. The communications were great, the pricing was very fair, and the service was excellent. Mashath is a professional. He was friendly, punctual, service-oriented, and thorough. I saw a lot of debris coming off our roof all around the house in the hours he spent working on our job, and he cleaned up every bit. This is an essential service, especially in the wake of the LA Fires. In fact, our neighbor's insurance scheduled an inspection and then dropped them for having debris in the gutters. Highly recommended!

The pros were relative novices at putting up the Christmas lights on our oak tree. Nevertheless, they did a reasonably good job.

Masath Delgado the owner of a1 Power Wash did an excellent job of power washing not only my garden shed but also also all of the pavers in my driveway which were very dirty. In fact, he did such a good job that I then hired him to paint and restore the patio and an old storage unit in my back yard. Masath is a skillful craftsman with an excellent work ethic. Iâ m very pleased with the work he did for me. Irina Ranahan

Mashath was very thorough, detail oriented at his job. He made sure to get the concrete driveway all clean and look like a new one. I hired him for doing exterior power washing, driveway power wash as well as for gutter cleaning. He did a great job.

The business owner came out the same day we had contacted him to give an estimate and scheduled us in for the next day to clean all the windows in our house. I would highly recommend this company. Masheth did a completely thorough job and the windows were spotless when he left. We would definitely hire him again and recommend him to others who are looking for a fair price and quality work.
