My landlord hired this company to stabilize the foundation of the house we’re renting, and I have to say, they are one of the best contractors I’ve ever had the pleasure of working with. Coming from a lifetime of experience as a home builder and contractor myself, I know what to look for when it comes to professionalism, workmanship, and customer service. These guys delivered on all fronts. Troy, the foreman, was very informative and professional. He explained every step of the process and kept me informed immediately whenever anything changed. Chance, the machine operator, was very careful to avoid damaging anything on the property, especially considering how tight the working space was. There was one minor incident involving a small piece of siding, but I was notified immediately, and the repair is pending. Considering the scope of the job and the challenging conditions they had to work in, I am completely satisfied with their work and how they handled the project. I highly recommend this company to anyone needing foundation work. They showed professionalism, honesty, and respect for the property throughout the job. As someone who has spent a lifetime in the building industry, I can honestly say these guys impressed me!

We had an issue with our sun room sinking on one side, the corner suffered from wash out. I called Firm Foundation, and I'm so glad I did. Misty was amazing with answering any questions i had, Nate was super helpful when he came for the estimate, explained what needed to be done and how they would make it happen. Trent, Brent and Enoch were great to work with. They kept me updated as the project was underway. They brought our patio back up, which closed a separation in the sun room where the ceiling meets the wall(photo attached) and now all 4 windows and the side door open. Very professional and courteous crew. I definitely recommend them!

Second time working with Firm Foundation Repair. Troy, Jah'ziah and Nick did a fantastic job with the crawl space repair. They were incredibly professional and communicated throughout the whole process. My home now feels safe and supported. Thank you guys!! Blake and his team were incredibly responsive when I called about a large hole near my foundation. They were professional and communicated extensively through the whole process. Blake even agreed to have his team come out on the weekend to expedite the repair. I am so grateful to Firm Foundation Repair for taking care of the issue immediately.

Push Pier Installation

Foundation settlement caused by unstable soil requires support that reaches far below the surface. Our push pier installation service transfers the weight of the structure to deep, load-bearing soil that doesn’t shift over time. This approach helps stabilize the foundation and can often improve elevation where settling has occurred.

Waterproofing Service FAQs

How can waterproofing improve indoor air quality?

Waterproofing helps reduce the moisture that encourages mold and mildew growth. A professional waterproofing service keeps basements and crawl spaces dry, helping the air in your home stay cleaner and healthier.

How does basement waterproofing protect a foundation over time?

Basement waterproofing directs water away from your home through membrane systems, trenching, and interior drainage. A trusted waterproofing service helps prevent cracks, leaks, and costly foundation problems caused by constant water pressure.

What are the most common signs that a home needs waterproofing in the Four State Area?

Musty odors, damp walls, peeling paint, mold growth, and standing water are warning signs. These issues signal that your home could benefit from a professional waterproofing service before the damage worsens.

What is the difference between interior and exterior waterproofing methods?

Interior waterproofing manages water that has entered a property using sump pumps and vapor barriers, while exterior waterproofing helps prevent water from reaching the foundation. Both methods are essential parts of effective waterproofing services.

Why is waterproofing important for homes in Joplin, MO, and the rest of the Four State Area?

Heavy rain, clay soil, and seasonal humidity make this region prone to water intrusion. Waterproofing protects your foundation, helps prevent structural damage, and keeps your home safer and drier throughout the year.
