"We had encapsulation and drainage put in our crawlspace by Tarheel Basement Systems. The crew they sent out was excellent! Jaylynn, Jahi, Derrick, and Travis. Great customer service and communication throughout the process. They were done in a couple of days and the work looks outstanding."

"Full termite treatment. They drilled holes in the foundation inside the crawlspace in most cases. Where that was not possible they drill the holes on the outside of the foundation. They covered all the holes to make them look as inconspicuous as possible. Very professional job."

"I had a flood for the first time in the crawlspace and basement. I called Regional Foundation & Crawlspace Repair to come out. They wanted 27K for crawlspace encapsulation, that was too much and I could do most the work myself. I instead paid them $5,000.00 to bury a geodrain and install a triple safe sump pump system. This is the job they did, they installed the sump pumps at the 3rd to lowest point in the crawlspace and this geodrain goes back and forth from uphill to downhill. The lowest point still allows water to flood downstairs. They also cracked a chunk of my foundation at the point of sump pumps egress. Outside they just threw rocks on ground were the water comes out and can get back into the ground to reenter the crawlspace. They got 1 star because the people were nice, their job was not. Update: they contacted me and said they wanted to make sure everything was good. A Girl and guy came out and noticed a couple things I did not and said they would fix it that their company does not do work like that. They dug up all the previous geodrain and moved it to walls, tried to level out the drain and changed the location of the pumps and the drain outside. She had a really good work ethic and never took a break. The guy was on the other side of house and think he did good too. Everything they did looked professional and looks like they fixed everything. They had to come back today to finish the work today, but had three of them. It all looks good and they tested everything. They apologized about the old work and were not sure went wrong, but I don't have a negative view of the company now and am satisfied with the work they did. Just nocking one star for the under trained individuals that came the first time, the second crew was great!"

Basement Waterproofing questions, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

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.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
