"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."

"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."

"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!"

"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."

"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 FAQs, answered by experts

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

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.
