"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

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."

"We purchased our home and the previous owners had Everdry Waterproofing perform work to stabilize the basement walls and waterproof. We have owned our home for 5 years and couldn't be happier with the work that was performed as well as how easy it was to transfer the lifetime service agreement from the previous owner to us. I would definitely recommend this company! Great work!"

Basement Waterproofing FAQs, answered by experts

Periodic inspections and addressing drainage issues prevent further damage.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

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.

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.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
