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.

The permiting process took a long time, but that's not their fault. The cost was very high but competitive with another contractor.

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.

My friend recommended this company and their tech Jason Dye to me, so I requested a foundation inspection/estimate. Jason is very responsive. He would text me and let me know the ETA when he was on the way. After he arrived, he checked everything very carefully. He gave me some good suggestions to help maintain foundation in a good shape, and even helped me set up the extension pipes from gutter downspouts. I enjoyed our communication and is very happy with his service. And he is super friendly to my dog!

I recently hired Bay Area Underpinning to underpin my home and my experience from start to finish was seamless.Jordan Christle, the lead foreman and his team were exceptional.

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.

Had BAU take care of a chimney that was leaning away from my home, fix my front door which would jam at times of the year and relevel my floors. This was my second time working with BAU who installed screw jacks and leveled my floors several years ago. This time, Juan took a look at the problem areas, took measurements, made recommendations that fit my needs and budget and answered all my questions. Gonzalo and team came to work on my property. They worked quickly to install piers under the chimney and in the crawl space. They put tarp down to keep the house clean in the areas they needed access and cleaned up after themselves each day on the job. They answered my questions and throughly explained the problems and solutions they would implement to level the floor. Overall, I'm pleased with their work, being on time each day, and communication skills and would recommend.

Several months ago, I noticed that doors in my house were no longer closing and latching. Specifically, my front door no longer locked completely. Once I got it fully locked I could no longer open my front door anymore, so I knew I had foundation issues. I called Bay Area Underpinning to come look at my foundation and do some measurements. We discovered that my front living room was sinking approximately one and a half to 2 inches. The crew, Lance Sladek, Jake Hall, and Eddie Shaw, crawled under my house and dug 30 to 40 foot holes in the ground to install piers that would lift my foundation. These gentlemen worked in very cramped dirty conditions in 90-100° weather. I was extremely happy with their work and their dedication to doing the job correctly. My after the foundation lift, my front door as well as several other doors in my home were able to close and latch again.

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!

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.
