"We had our crawlspace encapsulated a year ago. Ultimately, we are pleased with having lower humidity in our home and in our basement. This year, Austin came out and did my annual maintenance and was very informative and professional. He was very prompt with his arrival and kept me updated when he was on his way."

"The team worked diligently and professionally to Waterproof my basement after hurricane Helene caused water to come into my basement. They had to dig down into the foundation, fix the crack and apply waterproofing underneath my patio. While we haven’t had any big time rain since then, it’s been working against any kind of rain happening so far he also guarantees his work which gives peace of mind. They also encapsulated my crawlspace. It looks very professional and well done. It helps keep the humidity down in my crawlspace, and thus and the rest of my house. I would certainly recommend them to anybody who needs waterproofing solutions."

Basement Waterproofing FAQs, answered by experts

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

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

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.
