"The Groundworks folks (formerly Bay Area Underpinning) applied their foundation-underpinning technology and expertise to extend to bedrock, level, square up the foundation for an extensive house remodel. I was most impressed by the young man onsite supervisor, Josh who answered all my work done, how and why questions. I wish this info was provided up front by the estimator. (My design-build remodel contractor referred this company). "

Geico Builders specializes in meeting your expectations before, during, and after the project is complete. Our most upstanding quality is our accountability--you can expect us to own the work we complete for your home. Of course, we know accountability means nothing without proof, which is why we are happy to offer a 2-year workmanship warranty to all of our clients. This is a rare quality for this industry, but we wanted to prove to you that we stand by our craftsmanship through our home remodeling construction services. Every Crew at Geico Builders has been professionally trained and will treat your home with integrity and respect.
"We recently wrapped up a two bathroom renovation with Geico Builders and the end result speaks for itself! I just took a shower in one of our new bathrooms and it was like going to a fancy spa or hotel. I could not have envisioned it this great at the start, it has completely transformed our home. Feels almost unreal to have such beautiful, high end rooms in our home now! I had never done a remodel before and had barely posted the job on Angie’s list when Mila reached out and set the standard for what a consultation could be like. She had ideas for what could be done and David was nearby with his crew and could take a quick look so I got a brief feel for their teamwork. I talked with 5 groups in person and this team had a great cost/value balance and were willing to help me customize it how I wanted. Mila told me about their 3D design option and that reminded me that I do something somewhat similar for my job, so I mocked up the space in Maya and designed out several options that Mila looked through and helped me narrow down. Printouts of those posted on a wall at the job site really helped keep everyone on the same page. David’s attitude on the job was wonderful to be around, he values his team and is so positive. His crew worked fast and I had to hustle to keep up to order the materials in time. Both he and Mila went tile shopping with me and were a big help. There are so many options! If I were to go back I would have spent time picking out the exact pieces I wanted from the store we went with rather than done delivery—natural stone has huge variations so I was surprised by some of the tile when it came. The team was so fast that some of the stone had gone up before I saw it and several pieces were too dark. They were very understanding of the issue and fixed it when I brought pieces that were more representative of what we selected in the store. They consistently proved how trustworthy they were and backed up what they said from the beginning: that they were here for me, had my back and wanted me to be happy with the final product! Whenever I had a request or wasn’t sure with how something was coming together they took the time to walk me through it, listen to my perspective and shift if it made sense and would make me more confident in the process. I truly appreciated each time they double checked with me for my opinion and noticed when something was off! (For example, I had picked two grout colors thinking one was whitish and the other grey when in reality they were both almost the same in color! The crew caught it and I was able to get the right one quickly.) It was a huge collaboration, I’ll admit I wasn’t aware how much if my time researching and being available would be needed at first. It has been a steep learning curve but Mila and David were there for me. (Probably didn’t help that I designed and built some of the furniture to fit the space on the time investment side, but it paid off) Thank you Geico Builders for the stunning bathrooms! Your team’s work ethic, perseverance and expertise has been so appreciated!"

Foundation, basement or crawlspace waterproofing / encapsulations FAQs
Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.
A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
