Get matched with top exterior surfaces powerwashing pros in San Martin, CA

"It was a tough job a long time in coming. The roof and gutters are absolutely clean on both the house and pumphouse and moss proofed. We will have them back this fall for gutter covers."

"Hired them to pressure wash the exterior of my building. They did a very good job and my building looked like it got repainted after they were done. The team was very professional and great at communication on this project."

"Very personable, good communication, went out of the way to make our repair happen in a timely manner"

"The price was reasonable, and the job they did on the outside of our house + a large pergola was fantastic. Three full days to prep for the painting [the house is a large two story house] including powerwashing, filling in all the lines and cracks in the stucco et al. I was here to watch it all and I was VERY impressed. The crew that was here worked very well together and were always cognizant of taking care of the shrubbery. Lots of windows and trim, which were beautifully done. Great communication with us throughout the project. I would hire them again."

"He was great! Deck looks awesome!"

"Very easy to work with. I'd used them before but this time I got estimates from other contractors and was amazed how much more reasonable Cal Preserving was. The difference may be that the others pointed to additional steps that could be taken. Did Cal Preserving "miss" these things or recognize they weren't necessary--I'm inclined to believe the latter."

"Great group of guys, on time, great quality of work !"

"They were very professional, kind and courteous. Very friendly folks , they work hard, quick and fast. And pay attention to detail."

"Came quickly, clear quote and good job on cleaning."
