"The Tar Heel Basement Systems Team was a true pleasure to work with. From the very first meeting / inspection with Nathan S to the actual installation and receiving the final product. Also, just to note...the installation team with Tar Heel Basement Systems was excellent. They answered all of my questions and provided daily updates on the installation progress. They provided me with pictures and again answered ALL of my questions and was super patient with me. The work quality was top shelf. I am more than satisfied with the quality of work performed! Thank you again to the great installation team that installed my crawl space enclosure, shout out to Stephon, Matt, and Jorge (and Nate)...great job guys!!!! and very much appreciated! Also, thanks to Nathan S for all of his great advice and wisdom in planning this project for me. Yes, Tar Heel Basement Systems did a great job!!! Thank you!!!"

"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

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.
