Your home’s crawl space supports the entire building. As a result, even a single problem in your crawl space could lead to potentially hazardous issues in other parts of your home. If you’ve noticed issues like water stains, water damage, failing support piers, etc., you need Bay Area Underpinning’s crawl space repair service.

Fairfield, CA Crawl Space Repair

Bay Area Underpinning offers a wide range of foundation and crawl space-related services in and around Fairfield, CA. Some of the specialty services we offer include:

Crawl Space Foundation Repair
The crawl space of your Fairfield, CA home is responsible for keeping the building raised above the ground. In addition to housing your central air conditioning system and other units, you can also use it for extra storage space if it’s encapsulated. However, like other areas in your home, your crawl space is prone to damage.

One of the most common problems occurring in crawl spaces is deterioration of the support posts. The main reason behind this is the inability of the soil to support the posts. The solution is to remove and replace all the affected screw jacks. This helps lift the floor.

Signs You Might Need Crawl Space Repair

There are many signs of a crawl space in trouble. When you learn to identify these signs, you will be able to alleviate severe damage to your building and the expensive repairs associated with them. Here are a few signs to look out for:

  • Rodent infestation
  • Wood rot
  • Cracks in the foundation
  • Condensation
  • An increased indoor humidity level
  • Moisture content in the crawl space
  • Problems with the floor joists
  • Musty smell in the living area
  • High energy bills
  • Buckled hardwood floors
  • Metal surfaces rusting in the crawl space
  • Formation of mold and mildew

Bay Area Underpinning Fairfield, CA – Other Services Offered

Foundation Movement Repair

Foundation movement is a common problem faced by people living in hillside houses. If you face problems opening your doors and windows, notice cracks in your drywall, or sloping floors, it could be due to foundation movement. In such instances, you need foundation movement repair in Fairfield, CA.

For foundation movements on slopes, our foundation repair experts in Fairfield, CA, stabilize the foundation using drilled, cast-in-place concrete foundation piers. The process involves three steps:

  • drilling holes into the bedrock
  • placing steel reinforcement cages into the holes
  • completing the piers by pouring concrete into the holes

Settling Concrete Repair

Poor compaction, poor drainage, invasive tree roots, and poor site conditions are some reasons behind the settling of your concrete surfaces. Whether it is your walkway, sidewalk, patio, pool deck, or any other surface, uneven concrete can be a trip hazard and cause serious injuries to anyone visiting your home.

To lift settling or sinking concrete floors, we at Bay Area Underpinning use polyurethane foam injection. This is a minimally invasive process that involves the following steps:

  • small holes are drilled in the concrete slab
  • polyurethane foam is then injected through ports that are placed in the drilled holed
  • the foam gets underneath the affected slab and starts to react
  • the foam slowly expands and fills the voids beneath the sunken concrete lifting it back to its original position.

I hired BAU to underpin our foundation. After extensive research I learned that BAU does the best work and at reasonable prices. Jordan lead the crew that did the work on our house, and he was a joy to work with and we really trusted him and his team to take care of us. I am really glad we hired BAU, and we are happy to have our hillside home properly secured for the future!

We recently had foundation work completed. The crew was on time every day and worked hard to keep a very dirty job and their traffic through the house to a minimum. The crew chief, Robert Busch, was amazing. Telling us what was planned for the day, any unforeseen problems, and giving us a recap of what was completed daily. We could not have had a better experience with his communication and hard work. Everyone was respectful and friendly. I also thought that the evaluation and estimate experience was positive. Jim communicated clearly and we never felt that work being suggested was unnecessary. He explained clearly and showed us pictures of what was going on under the house.Hope we never need them again, but would use them in a flash.

Foreman Andrew is incredible and a leader. We hired BAU to perform a whole house underpinning job from December 2022-March 2023. Our recently purchased 1950's home sat on expansive clay soil and had been settling for decades. The project was a big job and complicated by the winter rains that occurred throughout many days of the project. Andrew was extremely professional, knowledgeable about every aspect of the job and managed the entire project class and skill.He communicates very effectively and is transparent to assuage any concerns that we had on the project. He also shows up earlier than anyone, and works the entire day, rain or shine, in the mud and trenches with his team. This leadership was impressive. Since the completion of our project, he has remained available and came out to make some minor adjustments promptly and free of charge. Without any hesitation, I would entrust BAU to do my foundation work with the demand that Andrew lead the project. Thank you Andrew and your crew for a job well done.

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.

I called in Bay Area Underpinning for foundation work. They were wonderful answering my many concerns, I received prompt return calls, the work was completed within an appropriate time frame, and the best thing he stayed with the estimate to the dollar. I loved the engineer, time frame, and minimal damage repair. I didn't know how my house was going to respond and even the marble and windows handled well. Unfortunately I didn't get the exact lift I wanted in the office even though they tried their hardest. My advice — call them when the problem first arises and the outcome and the house will lift with ease. I definitely recommend BAU. Because I live on a hill one pillar had to be covered – done. I also had a French drain installed to divert the water which was recommended. Thank you

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!!!

We used BAU to install piers and screw jacks to level our home. Really pleased with the entire process. The communication was stellar and the foreman made sure we understood each step as it was happening. The whole crew was professional, polite, punctual, and very neat. Each day they left the job site nice and tidy. The overall result is amazing. Our floors are level and the house looks great. Would highly recommend for any foundation/leveling needs.

I can’t praise Bay Area Underpinning enough! Everything from their support team, to their customer service, and the quality of their work has surpassed my expectations. I’ve used other foundations companies in the past and they weren’t great for many reasons – Bay Area Underpinning has none of the challenges I’ve experienced elsewhere, and massive positive upsides! Would highly recommend!

Bay Area Underpinning is OUTSTANDING!! Cody, Andrew, Francisco, David and their underpinning and concrete teams did exceptional work installing underpinnings to stabilize our house, then replacing the concrete patio that had to be removed to do the stabilization. Everyone on the teams were efficient, courteous, highly skilled, and thorough. I cannot recommend Bay Area Underpinning highly enough- through each step of the process, from the initial assessment and work quote, to the work and follow-up itself, the staff and crews of Bay Area Underpinning ensured that I was informed, reassured, and we’ll take care of. They were thoughtful about doing their work efficiently and cleaning up after the work was completed. I cannot recommend them highly enough!
