"If you want to have your foundation waterproofing job done the right way, then I recommend that you have Dani and Sealtech Waterproofing take care of the project for you. They are extremely honest, hardworking, skilled and professional. When I had their work inspected by the County Building Department, the inspector termed their quality of work as "outstanding". After waterproofing I also had them backfill the foundation which was also performed to the same high standards. Everything was completed at a cost that was more than fair. I first contacted Sealtech because of the good reviews I had read about them, but now I'm happy to make the same kind of recommendation based on my own personal experience."

"Gerber and his teammates Edwin and Kyriee did a great job. They completed the basement waterproofing quickly and professionally. They had to carry a large number of bags of concrete debris up a slippery grass slope, and they did this without complaint. Thank you guys for a job well done."

"Once the emergency cleaning and vapor barrier liner were installed, we were encouraged to wait for a few months to let the space really dry out. It was a good thing because the entire southeastern part of North Carolina needed multiple services to get back to normal. Falcone was available for an assessment visit within a month, and was ready to work on our contract within a helpful time frame. They repaired the water damaged joists and replaced the insulation in one very busy day.The called occasionally just to check in,, arrived early for our work day, finished and cleaned. The workers called several times with updates as t hey worked. They took photos of this space that homeowners rarely ever enter. I know what work was done and how it looked on a specific date. Valuable information when your house is in a storm zone. They accepted a mailed check for payment since I was spending insurance money and needed to keep track of its dispersal."

"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."

"Having owned four different houses the past 16 years, this was hands down the best experience with a plumber... ever. We hired WyattWorks to install a laundry sink (the stainless over cabinet kind) which required drilling through the floor to tie-in with supply and drain pipes in our basement. Jeremy performed the work flawlessly and was a true pro: measure and recheck, plan and dry fit, and clean up the work area during and after. The whole process from start to finish was painless!"

Kevin & Leander came promptly and worked diligently with covering up house items while they cleaned up & removed the wet walls? All 3 of these gentlemen were very professional, kind and courteous. Would highly recommend this company to anyone?"

Basement Waterproofing questions, answered by experts

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.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.
