"Your review Now retired I spent 45 years building over a billion dollars of infrastructure! Immediately connected professionally with Kevin at San G builders. Relationships need to be good, open and honest are paramount to build anything successfully! Mutual respect is the foundation! Remember there are ton of questions and decisions to make when you build anything and thats why you have to connect and communicate successfully! Kevin Morrison from San G delivered an exceptional construction product to us! I highly recommend Kevin Morrison and his amazing company San Gorgonio Builders! Dave"

"Things at our home were getting "old", but who to choose to help us with modern and innovative renovations? Based on experience and previous work we asked the San Gorgonio Builder to help us and we are glad we did. Kev in was immediately open to and fully supportive of our suggestions. The result was a calming and peaceful "tub" room and then a dramatically lighted and exciting shower like none I have seen before. Thanks Kev!"

"Hired Kevin owner of San Gorgonio builder to covert my carport into a garage. I had several people bid and their prices were either outrageous or they told me the conversion could not be done. Kevin showed up and delivered amazing quality work and kept us updated all throughout the process. He took care of all the permits and dealt with everything. Me and the wife could not be more happier! I would highly recommend Kevin for all your construction needs. If you want someone honest and perfectionist with an amazing crew, look no further. Thanks again"

"Kevin and his team are AMAZING. We have never hired a contractor for home renovations before and we could not be happier that we found San Gorgonio Builder. We had our 24-year-old primary bath remodeled including removing the showertub insert and creating a walk-in tiled shower complete with two niches and a separate dog wash station, added plumbing for a new double vanity, and new flooring, paint, lighting, baseboards, etc. The quality of work is exceptional even a couple of extra things we asked for along the way! They were on time and swept up behind them on their way out every day. We signed a contract with milestone payments which made us so comfortable. The bathroom is everything we hoped for, and we cannot wait to plan another project and call Kevin to do it! Thank you San Gorgonio Builder... we are so grateful. UPDATE 2025 - We were so excited to have Kevin and his team work on another project for us... removing the enormous window in our bathroom for a smaller, more appropriate size which included matching the stucco outside. San Gorgonio Builder is just the best and we cannot thank them enough for their professionalism and craftsmanship. We wish we had done it sooner, it is perfect. If you are looking for a contractor, Kevin is your guy. DO NOT HESITATE TO GIVE THEM A CALL. Kevin, thank you for another amazing update to our home, we appreciate you and your entire team."

"I am extremely happy with my kitchen remodel. This is the second time I have used SGB for a remodel project. The first time was for a small bathroom remodel and this time for a kitchen remodel. The entire team was a pleasure to work with. I was comfortable with leaving them in my home alone. They were neat and respectful. Kevin addressed all of my concerns and fixed anything that I asked. Kevin is also good with communication letting me know when his team would be at the house and what was being done. The workmanship and quality is outstanding. My kitchen exceeded my expectations. I highly recommend him"
