Alfredo Oliva
Jesse delivers excellent work every time! He’s done me entire backyard and front yard with high quality custom work that I couldn’t be more happy with. I would definitely recommend him to anyone looking to do future landscaping projects!

Jesse at JJ Masonry built two gate walls for me. He did a great job and cleaning up afterwards. Also in a pinch I had a permit inspection on Monday which Jesse came on Saturday before and finished extra work in time to pass the inspection. Would recommend him if you need block work. Going to use him again in a few months
