"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."

"They are very professional and honest! We had water intrusion into basement from wall during recent heavy rain storm. I contacted Falcone (they were on recommended service provider list of our subdivision) and Sharese got back to me very quickly. Communication was very smooth and professional as she scheduled me for an inspection. The technician Walter was friendly and did a professional inspection, after which he determined that the issue is the gutters dumping water on the ground by the basement. He didn't recommend any work be done in the basement. I truly appreciated his professionalism and honesty. If I ever have issues with the basement, I will call Falcone in a heartbeat! Thank you!"

"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!"

Basement Waterproofing questions, answered by experts

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

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 moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.
