Get matched with top deck pros in Portola Valley, CA

"Our large deck was sorely neglected - no maintenance in at least 8 years - and I worried it was beyond help or would be cost-prohibitive to rehabilitate. Rupert and Michael breathed new life into it! Rupert (company principle) is very responsive, and he was able to give a quick informal estimate based on some photos and I texted. This made it very easy to start working together right away. Now the deck looks beautiful, and they were able to stain our wooden deck furniture to match. Great makeover for our deck and lovely folks to work with!"

"Cal Preserving did a great job on our very difficult to install Ipe (Brazilian Walnut) deck. I would definitely use them again."

"I am writing this review on behalf of Javier Flores I engaged Javier Flores to build a deck in my back yard. I could not be happier with the job he did. Javier and his brother Daniel arrived promptly at 8:00 a.m. each day and worked hard all day, with the exception of lunch. The two of them work together very well. When they finished the deck, I told them that I would sweep off the saw dust, but Javier wouldn’t let me sweep the deck, He told me I am paying him to perform that duty. Javier and Daniel are experienced hardworking men who value precision, and pay attention to the littlest of details. Our new deck is as stiff as concrete, no sags, no squeaks at all. I am so happy with the deck, that I am going to have them install the deck railing also. I would gladly recommend Javier to anyone that needs a deck. Henry & Mary Anne Price"

"We hired Brian to complete a full deck tear out and rebuild. He was responsive, budget-minded, on-time (7 am), and completed our project in a timely manner. He and his assistant built an amazing, high-quality deck. Their work was impeccable. We would highly recommend Brian and his team for any deck work you might need. We will enjoy this deck for years to come."

"This company is the very best. My two old decks now look like they are new. The crew is very detail-oriented especially with the prep workâ -power washing and sanding â so the final staining is perfect. My windows were covered while they worked and everything cleaned up when they finished. Also, the price was very reasonable. I definitely recommend them!"

"I recently had my roof replaced by OT Bay Builders, and I couldn?t be happier with the results! From the initial consultation to the final inspection, their team was professional, punctual, and detail-oriented. They provided a thorough assessment, offered a fair quote, and completed the project ahead of schedule. The crew was respectful of my property, ensuring a spotless cleanup after the job was done. The new roof looks amazing and has already stood up to heavy rain without any issues. I highly recommend OT Bay Builders for anyone looking for reliable and high-quality roofing services!"

"EXCELLENT JOB! They built me a composite deck at a very reasonable price and I'm very happy with it. Thank you!"
