Bay Area Underpinning Napa, CA – Other Services Offered

Foundation Movement Repair

For homes located on a hillside, one of the most common issues faced is foundation movement. This is usually indicated by signs like sloping floors, problems opening doors and windows, drywall cracks, etc.

Drilled concrete piers are an excellent solution to repair foundation movement and settling foundations. They are also suitable for building a deep foundation system for new construction projects.

Uneven Concrete Repair

Uneven concrete surfaces around your home can create trip hazards that can cause serious injuries to both residents and visitors. If someone gets hurt, you could find yourself facing an expensive lawsuit.

Polyurethane foam injection is perfect for lifting sunken or uneven concrete. Dime-sized holes are drilled into the affected concrete and then the foam is injected underneath the slab. The foam rapidly expands to fill the void, thereby raising the slab. This is a minimally-invasive procedure and your concrete surface will be ready to use within minutes.

This company gets a 10 out of 10 from me. From my initial consultation with Rick DeSoto to the work performed by foreman Raul, and his team Jonathan and Demareon, this was the best possible experience in working Bay Area Underpinning for the first time. The crew was professional and adjusted the leveling jacks (and even added a couple as was needed) with care and great attention. Pricing was very reasonable too. I'll never trust any other company to do this type of work at my home. 100% satisfied with the work and my interactions with the crew. A+ work performed = A VERY HAPPY CUSTOMER!!!

Bay Area Underpinning is THE company to use for foundation work. Aaron, and his crew, were incredibly professional from start to finish. The team kept the work space clean and tidy, communicated well, and updated me as timelines were solidified. They were always on time and ready to maximize their output for the day. I would recommend them in a heartbeat.
