"My sump pump goes off all the time; I think there is a natural spring around my house. Joe Silverberg, my local U.S. Waterproofing rep., has been wonderful in advising me on my sump pump replacement, (which works beautifully by the way and gives me so much peace of mind!), and on sealing cracks in my basement walls. Whenever I have needed him, Joe comes over right away to address the situation. I highly recommend Joe and U.S. Waterproofing, who does excellent work and stands by that work!"

"Project: Radon Mitigation Jordan explained what was being done for the project. He was very thorough in making sure the crawl space would be sealed and vacuum was proper in the crawl and basement. I would recommend Gardner Environmental to anyone needing Radon mitigation work."

Customers say: Quality work

"Very pleased with the prompt, friendly service. Very efficient and told me exactly what had to be done and what it would cost in advance. The old, limed up water heater had to be a bear to haul up and out of the basement. It gives me peace of mind knowing that the appliance was installed correctly by an experienced plummer and that it will last for many years to come."

Basement Waterproofing questions, answered by experts

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

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.

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.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.
