Crawl Space Repair – Folsom CA

A sagging crawl space is perhaps the most common crawl space issue faced by property owners around Northern California. Crawl spaces often sag due to the following:

  • The soil around the pier blocks is soft due to water intrusion into the crawl space, caused by poor drainage around the property’s exterior.
  • The floor was not given adequate support during initial construction.
  • The existing screw jacks were not installed properly and have no corrosion protection.
  • The installation of interior crawl space support posts in problematic soils has caused them to settle.

Your sagging crawl space can often be repaired by simply replacing the deteriorated screw jacks with new ones. When the new screw jacks are in place, the floor can be lifted.

Common Signs of Crawl Space Issues

The most common signs of crawl space problems are:

  • Interior wall cracks
  • Sloping floors
  • Condensation
  • High energy bills
  • High indoor humidity
  • Increased moisture level in the crawl space
  • Water problems
  • Rodent infestation
  • Wood rot
  • Foundation and floor cracks
  • Misaligned doors and windows
  • Spongy floors

Other Services Offered by Bay Area Underpinning in Folsom, CA

Drilled Concrete Piers

If your home is located on a hillside and you have sloped floors, difficulty opening doors and windows, etc., you could be experiencing foundation movement and this can be fixed using drilled concrete piers.

Drilled concrete piers are commonly used when there is expansive soil, when the soil’s upper layer is weak, when the soil is prone to erosion, and also when there are lateral forces pushing against the foundation. Some of the major applications of drilled concrete piers are:

  • Stabilizing foundations
  • Retaining walls
  • Seismic loading
  • Deep foundation systems

Push Pier Installation

Push piers, also called resistance piers, are an efficient solution for homeowners facing foundation settlement. Push piers are used to lift and permanently stabilize a foundation.

Heavy duty steel brackets are attached to the foundation and then the piers are driven through the brackets deep down into load-bearing soil. Once the piers are in place, the foundation can be lifted using a synchronized hydraulic lifting system.

1. Call Center ***** – they took the call after 6:00 PM and were extremely professional. Guy on the phone (sorry I didn't write is name down), was so kind and emailed confirmation immediately. 2. Pre-Visit Confirmation ***** – Email, text and phone calls to confirm the time and prep me for the visit. Incredible. Nobody is doing this right these days and BAU absolutely has it nailed down. 3. Estimator ***** – I wish I could offer more than 5 stars. Joe Le Bel is the most professional tradesman I've met in a long time. Others are good too, but Joe is the gold standard. He sat with me to ask what I was concerned about and what was important to my family. Who does that???? Oh yeah, Joe did. So comforting. Joe was professional and respectful of our space. Was careful to be conscientious about where he placed his gear, tools and instruments. Super clean going under the house without tracking dirt and debris back into the house. (The inspectors from HomeGuard could definitely take notes on this!) Then, once Joe finished, he sat down with us and talked us through all the different aspects off his inspection. What an extremely positive interaction. I would 100% recommend BAU and Joe. Can't get any better than this. Thanks BAU for a great culture of excellence. Thanks Joe for being such a good human and professional!

When we had our 1960s home underpinned, the consultant arrived on time to give us a quote. He gave us different options for work to be done and had solutions to cutting cost on things that weren't absolutely necessary. The work was done within a week. All of the workers were professional. Something that stood out the most was the way the workers communicated with each other. They weren't your typical construction crew in this sense. They were very kind to each other and supportive of each other, even when they were in a difficult situation. This isn't common in construction. As for the cost, it was what we had expected and we don't have any complaints. Our house is level now and doesn't feel like we're drunk walking in areas that were previously sagging. There's a reason Bay Area Underpinning is #1 in the area. Would recommend, even if they aren't the cheapest- they get the job done right.

Jonathan Falcone was great to work with. He visited a couple times and walk through multiple options of design to rectify the sloping issues of our house. He was attentive and took multiple calls to help with the review and planning process. I would highly recommend to work with Jonathan! Looking forward to the project kicking off and the sloping foundation to be fixed!

I recommend Bay Area Underpinning for an important reason: honesty. After careful inspection, their agent, Richard, told me the truth, which was that my crawlspace was fine, that I had no problem with moisture or settling. And then he took the time to show me why. He could have tried to sell me on doing a lot of work, but he didn't. This kind of honesty is impressive! Call Bay Area Underpinning to inspect your crawlspace. You can trust them. If they say it needs work, hire them to do it. I am almost sorry I couldn't!

We had an amazing service experience from David and Rico of Bay Area Underpinning. David and Rico were very professional, super nice, and worked hard on leveling my floor. They arrived on time after giving me a call earlier to let me know they are on the way. They put on shoe covers to make sure my floor is protected. They patiently listened to my inputs and addressed my concerns with competence and great care. And they would not leave until all the uneven floor areas are fixed to my satisfaction. This team deserves my 5 star rating.

We had a fantastic experience with Bay Area Underpinning, lifting our foundation four and a half inches of our old 1958 Napa house! After careful review of several contractors, we chose Bay Area Underpinning and so glad we did! The entire process was smooth from the sales engineer estimate to the completion of the job, the communication was outstanding all along from day to day and ourblift was a big job with a full week of labor intensive work. I especially want to thank Foreman Cody Summers, Co-Foreman Ken Hamlin, and Installer Nikolas Klein for their outstanding work and customer service! They are the best and ensured that I was happy with the progress and completely satisfied. I also want to thank Superintendent Kevin Gaeden for his outstanding communication! My wife and I are completely satisfied and happy with the outcome! It was a great choice with great value after the job was complete! We would hire Bay Area Underpinning all over again! Thank you very much for a job well done!

We just bought a house and literally every single metal pier in the crawlspace was rusted out. Bay Are Underpinning came in and did an awesome job. Their inspector Aaron was super thorough in assessing the damage and explained everything in detail. Then, the repair crew of Eric, Jesus, and Andrew came in and knocked out the entire job in a day — a huge relief considering we had a ton of other work we need to get done before moving in. The work is not cheap, but they offer financing options and stand by their work, so I feel very good about the entire job.

Had Bay Area Underpinning come out for a free estimate to check my foundation. They verified the appt 2 days before along with day of, I got a link as to where the technician was and he was on time. Ronald was very professional and informative. He was able to answer all my questions in a way I could understand and I got a copy of all the findings. Would definitely recommend for anyone needing an inspection.

Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!

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.
