"I will start by saying that the work they did waterproofing our basement looks good, and I am hopeful that it has fixed our problem. We've had a good bit of rain recently, and so far, so good. That, of course, is the most important thing. That said, I chose this company, even though they were on the high range of the quotes I received, because I did not mind paying more for a professional experience and great customer service. I was disappointed with this aspect of the experience. The day they were scheduled to begin they never showed up, and I ended up calling them three times that day. The woman in the office was responsive, but she said that they did not know where they were. The next scheduled appointment was for the morning, and they did not end up coming until 2pm, again without any communication. Both instances were due to car issues, but a phone call to keep me updated would have been appreciated to allow me to better plan my day. When they did start the work the crew leader was friendly and appeared to know what he was doing, but he offered little information about the job unless I asked. Prior to the work being done, I also had to keep after the sales representative to put their warranty in writing. Twice he promised to email it to me, and only after contacting him a third time did he send it through. If I had not paid so much (over $11,000) I would have given them another star, but at this price point my expectations were high."

"Ken, Gerry & Malik finalized the waterproofing issue in my basement. These guys were fabulous! Not only did they clean up the basement area very well but walked me through the scope of the project as well. I found them to be very knowledgeable and customer focused. My personal experience working with everyone at Tar Heel Basement Systems has been extremely positive and I recommend them highly."

"A great group of folks - professional, courteous, friendly, and thorough. What more could one ask for? They 'upgraded' the insulation in my attic, and discovered and addressed a couple of problems I was not aware of. Great job! I'll refer you to all my friends. It's good to know that you also do crawlspace/basement encapsulation."

"Crawl Space Jam did an incredible job of encapsulating and waterproofing our crawlspace! Throughout the project, Chris Venzon-owner, continued to provide progress reports, before and after photos, and to make us aware of any operation that might create noise (critical as one of us works from home). Chris even went beyond the scope and replaced the door to our crawlspace to ensure everything was sealed well. We would highly recommend Chris and Crawl Space Jam to help you with your crawlspace concerns!"

"Lane came out and listened to all our needs. He walked us through a very clear plan for our basement. They gave us a reasonable quote and were able to schedule us a few weeks later. It took them 2 days to do the work and it was done very professionally. The crew was extremely nice. They brought extra plastic to make sure all our belongings were covered. They even helped me move my washer and dryer! They made sure everything was clean and to our standards before they left. The whole experience has been great and I highly recommend them for whoever is having water issues in their basement or crawl space."

Basement Waterproofing questions, answered by experts

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites
