Get matched with top addition to existing structure builders in Portola Valley, CA

"We needed more space for our growing family, and the addition they built blends in seamlessly with our original home. From permits to the finishing touches, everything was handled professionally. It’s like it was always meant to be part of the house!"

"I went with Sky Tech Builders on a room addition. I decided to hire this company because they gave me very realistic offer, were available in short time and I also got some recommendations from my friends. The project started soon after we signed a contract and it went very smooth, there were no issues or hidden costs. Sky Tech Builders team was professional, efficient, quick and communication was great. They finished this project ahead of schedule, quality is superb and final product is excellent. I couldn't ask for more! Thank you!"

"These folks are conscientious, honest contractors. I have hired then for many years and I am never disappointed in the workmanship and quality. They always back their work and came back to fix something that they worked on. An added bonus is that they are just great people. I would highly recommend them and I am picky."

"I set off to find a solid contractor who had great reviews and was relatively affordable. I probably looked at over 15 contractors before finding Gili! He stopped by our new place, gave us helpful insight while he looked around, and quickly emailed us a thorough quote with a breakdown of the cost for material and labor. He was the ONLY contractor we met with who bothered to explain all the costs with detail (which were very reasonable). Clever Design and Builds crew got to work quickly, arrived on time every day they were scheduled to work, and cleaned up at the end of the day. They did a complete kitchen remodel, knocked down a wall to open up our living space, and installed gorgeous laminate floors that resembled exactly the kind of hardwood I would have wanted to have but at a more affordable price. They also put down tile and we could not be more thrilled with the results! Roy was our foreman and his team did an absolutely amazing job, the final result is beautiful! Not only was Gili and the entire team absolutely professional and produced stunning results, but they were able to complete the job quickly and adjust any issues that came up so we could get the exact vision we were hoping for! All in all, we could not be happier with Gili, Roy, or their work and we are so glad we decided to go with them! We absolutely will use them in the future for any other projects we have."

"Transformation begins the moment My Remodeling Group steps into your home. For this kitchen remodel, every detail was carefully planned to improve flow, storage, and style. From modern cabinetry to clean finishes, the space was redesigned to feel open, functional, and welcoming. The result is a kitchen that supports everyday living while adding lasting value and visual appeal to the home."

"RandB Master Construction handled our bathroom renovation in Sunnyvale. They used quality waterproofing, tile and fixtures, and they coordinated plumbing and final inspections. The finished bathroom feels modern and luxurious, and the project covered 85 sq. ft. primary bathroom. The job kept moving without unnecessary delays. The process felt organized, and the team was easy to work with from beginning to end. Everything came together beautifully, and we would gladly recommend their crew."

"It went well. There were some surprises. Damaged shingles and structural damage were discovered once we were underway. This lengthened the duration and cost of the project. Fortunately Sigura has carpentry capabilities in addition to their painting skills and were able to make the needed repairs before resuming the painting. The rest went without a hitch."

"Adir and his team exceeded all expectations with our ADU project. They helped us refine our design, handled permits efficiently, and executed the work beautifully. Every part of the build shows quality and care. What I appreciated most was their communication. They kept us informed the entire time. It?s rare to find a company this reliable."

"To create my ideal kitchen, the staff at Bay Remodeling Kitchen & Bath went above and beyond. They listened to my thoughts, made useful recommendations, and transformed my kitchen into a lovely, hospitable area."

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"
