Understand what the crack is telling you. We inspect basement foundation cracks, water entry, and signs of movement, then explain the repair your home needs.
The crack’s pattern, location, and changes over time all matter.
Foundation cracks can develop as concrete cures, soil conditions change, or pressure builds around basement walls. Some affect the surface; others allow water through or accompany movement in the structure.
Basement foundation crack repair starts with identifying the type of crack and its underlying cause. We explain whether sealing the crack is appropriate or whether drainage, wall support, or other foundation work also needs to be considered.
Changes in the crack or the surrounding wall deserve a closer look. Tell us what you have noticed and when it began.
Recognizing the pattern helps you describe what you see. We inspect the crack and the surrounding conditions before recommending a repair.
The repair method follows the inspection. Crack sealing addresses a water-entry path; ongoing movement or wall pressure may need additional work.
For suitable accessible cracks, an interior injection repair helps seal the opening through the foundation wall.
An epoxy surface seal and expanding urethane resin help fill the crack. Finished walls may need to be opened for access. We explain the preparation, material selection, and whether other repairs are needed in your written plan.
Some cracks are better approached from outside the foundation, depending on access and the conditions found.
The wall-clay method uses sodium bentonite at the crack location. The clay expands when exposed to moisture to help limit water entry. Your specialist determines whether this approach suits the wall, drainage, and surrounding soil.
Cracks can allow water to damage finishes and belongings, create damp conditions that support mold, and leave openings around the foundation. Addressing the cause helps protect the repair. We evaluate moisture and drainage alongside the crack, and explain when broader foundation assessment is needed.

Crawlspace Brothers resolved my flooding and ground water issues. They diagnosed and installed a partial encapsulation. My moisture levels are now under control, protecting my home’s foundation and improving air quality. I had consultations from 5 companies, but Crawlspace Brothers’ design was right-sized and at the correct price. They also gave me different options. I was satisfied with the quality of work. The staff were clear communicators. The price never changed.
All around great experience. Got the job done professionally and in a timely manner. Would recommend. They sealed a vertical crack in my foundation and no water since!
We used this contractor for our crawlspace and these guys are great! From Matt’s first visit to provide an estimate until the job was completed, we experienced nothing but professionalism and timeliness. We had moisture in our crawlspace of our new home and the builder grade vapor barrier was useless. Since our home is new and the foundation was properly sealed and drainage was installed properly around, all the moisture in the crawlspace was coming from the dirt under the vapor barrier. Rather than up-sell us on a full encapsulation, Matt recommended we just improve the vapor barrier and install a large space dehumidifier. This saved us thousands by not overdoing it. They installed both for us after removing the cheap builders grade vapor barrier. The installers were very professional and clean…and they did an excellent job of cleaning up all scraps and debris before leaving. We hardly even knew they were down there working because they were so quiet, too! Now our crawlspace humidity is maintained at 50 - 55% and the dehumidifier they installed seems to have corrected our issue. But, just in case, they have also followed up with us a couple of times to make sure that the work they did was sufficient. One of the follow-ups was a visit by their project manager to make sure the installation was done correctly and that the dehumidifier was working properly. He also told us what to do if we ever have an issue and thoroughly explained all the error codes we might see if the dehumidifier ever fails…including an overview of the 5 year warranty. I can’t recommend CSB enough! We extremely glad we hired them! Scott D
Very professional crew. The work looks amazing and I am looking forward to protecting my home’s foundation with the measures they showed me. Highly recommend you give them a call for a quote.
I highly recommend Crawl Space Brothers. Thank you Jeremy, Kyle and Otiz for a job well done. We contracted for the work in the Spring with Marcus, our representative from Crawl Space Brothers. We held off on starting the work until a water issue on the foundation had been resolved. In June I projected we would be ready in October. Marcus contacted me several times leading up to the schedule install date. It was Marcus who sold me on the work to be done. But it was Jeremy, Kyle and Otiz, the crew from Crawl Space Brothers, who exceeded my expectations. Marcus came on the first day to make sure I was pleased with the work being done. The crew cleared the crawl space of items that had been stored and forgotten. During the job, I checked on their progress a number of times. They explained exactly what they were doing. At the end of the first day, they cleaned up the area and left it very orderly. The crew arrived on the second day as scheduled and worked until the job was completed. We have three crawl spaces and this is the first space to be completed. The other two spaces will be encapsulated once construction is completed. Already I can tell a big difference in the space above the area Crawl Space Brothers encapsulated. The humidity has dropped and I no longer smell moisture. I will definitely request the same crew when we are ready to encapsulate the other two spaces.
