Causes Of Crawl Space Problems

When you have problems in your crawl space, your home may have signs of settlement even though there’s nothing wrong with your foundation. Spongy floors, furniture that shakes as you walk by, and doors and windows that don’t easily open and close are a few common signs of a sagging crawl space.

Crawl space foundation problems happen for various reasons including,

  • Your home’s interior crawl space support posts were installed in expansive soil. Expansive soil swells as it absorbs water and then shrinks by that same amount when it dries out. This seasonal swelling-shrinking cycle creates movement and can cause support posts to settle.
  • There’s excess water in the soil around your home’s foundation that isn’t able to drain off. Water gets into the crawl space and softens the ground supporting the pier blocks.
  • There’s deterioration in the screw jack base. This can happen when the screw jacks were improperly installed and don’t have protection from corrosion.
  • Bad design. Sometimes, the design didn’t include enough support for the floor.

Crawl Space Foundation Repair Methods

We use screw jacks to repair sagging crawl spaces. They come in various sizes and weight capacities. Because the existing piers blocks are usually in good shape, they probably won’t need to be replaced. We just remove the posts or deteriorated screw jacks and then replace them. Once we do that, the floor can be lifted.

Benefits of Using Screw Jacks

  • Screw jacks are versatile and allow us to adjust floors in areas where access is limited, like crawl spaces.
  • Screw jacks are easy to install and eliminate the need to cut new wood posts if the crawl space needs to be serviced for repair.
  • Screw jacks can be easily adjusted if necessary.

I recently scheduled an inspection after concerns around my foundation and worked with Jim Rivera on my home. Jim was super helpful and knowledgeable in assessing the severity of my foundation issues, while also assessing other parts of the home that might be contributing to potential damage in the future. I was surprised how helpful he was in helping me understand different scenarios, planning for near-term/long term fixes, and putting my mind at ease over the foundation issues. I'd definitely recommend working with Jim and his team!

Thank you Bay Area Underpinning for saving the day! I was in a challenging and prolonged situation since going into contract with EagleLift for the stabilization/lift for my house. After a long permit process and continuously delayed start dates, I was informed that EagleLift had been acquired by Groundworks and I’d have to wait a few more month before any progress could happen. It was a deeply frustrating process but the EagleLift team was able to connect us with Bay Area Underpinning (another Groundworks company) who were able to take over and expedite the project. To my surprise, James T. from BAU reached out quickly and assigned a team to come to my house within a week! The team that ended up working on the house, specifically Ish, John and Abel were exceptional. They were diligent, knowledgable, friendly and deeply considerate. They are truly pros who knocked the project out in no time which was reassuring since I was nervous that this project was gonna stretch into the rainy season. My house feels so stable now (minimal cracks too) and the considerable slope is now practically nonexistent! Thanks a lot James T., Ish, John, Abel and the BAU team for taking really great care of us.

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.

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!!!

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.

Last week, my car cut off while exiting the highway in Dixon, and I was stranded in a dangerous spot. Fortunately, your employees who were driving a Bay Area Underpinning truck, Erick Baez, Jesus Vallegomez, and Wesley Almaza stopped to help. They worked hard to try and troubleshoot my car and even pushed it out of the street to a nearby gas station while I waited for AAA. Their professionalism, kindness, and respect were incredible. I'm so grateful for their assistance, especially since I’m a woman who was alone in an unfamiliar area in the evening. Thank you, gentlemen!

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!

I will sleep much better tonight. I noticed a crack in my foundation and called Bay Area Underpinning. Hunter came out and walked the entire property and went underneath. He identified one other issue that I knew about besides the crack and told me they could fix that too. I had no idea you call structural engineers for chimneys. His quote was fair to me and you can't beat the warranty. Today Jesus Villagomes and Erick Baez came out and fixed the crack, they also looked around underneath and reassured me AGAIN that my house was in good shape. Because I caught it early they were able to fill the crack and then add a carbon fiber exposy seal. They also sealed the crack from the outside, even though they had already filled it in under the house. They were professional, answered all my questions, no matter how many and honestly were just pleasant to work with. They also explained my maintenance plan so I knew what to expect. I would absolutely recommend this entire team, to stay professionally kind in high heat is amazing.

I had a great experience with Bay Area Underpinning. They fixed my foundation, which was a substantial job, in a matter days, and did all of the engineering and permitting at a very fair price. I cannot say enough good things about Tyler, Angelo, and Louise, who did all the hard work. They were on time each day, very diligent, and patiently answered all of my questions. Then, when the job was finished, they cleaned the work area and left it in a better condition than they found it. That was awesome, and tells you what you need to know about these guys and the company. I couldn't be happier.
