"Wes was fantastic in helping us with a home we were considering purchasing. We did not go forward with the purchase as a result of Wes explaining what the issue was and our further review of additional cost. He was professional, punctual, and easy to work with. Highly recommend if you need this work done."

"It took two days to tear out the old insulation under the bottom floor and install encapsulation in the whole crawlspace. Nick and his crew did quality work getting the job completed. They also patched holes in the foundation, hauled off all the old, dirty insulation and torn vapor barrier. All-in-all a very accommodating crew."

"Lowcountry Foundation Repair came highly recommended by our contractor and they did not disappoint. The team was AMAZING! Super responsive, professional, very hard working and diligent. The team worked clean and did a gorgeous job on our crawlspace encapsulation. Alex and his team (Francis & Dedric) were THE BEST. We really had a great experience and are so grateful for their expert work. They're really an impressive team."

Basement Waterproofing FAQs, answered by experts

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

Yes, a crawl space can add value to your home. However, there is a higher chance of it adding value if it is an enclosed crawl space, as this reduces issues caused by excess moisture in the home. That being said, a basement does add more value than a crawl space.
