This company is the best I have ever worked with. Wish I used them to build my home. Great service, On Time! and did work that wasn't in the scope of the project. Unreal! Thank you Jonathan

I hired John Jacobs Construction to Design and Build our Room Addition. They kept their word throughout the project. Their craftsmanship and attention to detail was second to none. John Jr. was the first on the job and last to leave every day. They made extraordinary efforts to minimize dust and cleaned the job site daily. My wife and I are thrilled with the results and highly recommend this company.
John F. San Clemente, CA
Best general contractor I have ever used. Room Addition with highly complicated hill side foundation. John and his father were professional and honest throughout the entire process. All work was of the highest quality, John completely satisfied my difficult tastes, and did it all with a smile. Respectful of my home, and my family's space. They cleaned up after each day, to the point that we could live in the home while the work was going on. I highly recommend John Jacobs Construction, please feel free to contact me for a referral.
