"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."

"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 FAQs, answered by experts

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.
