"Headly was very knowledgeable and professional. He was also very honest to tell me that the issue was not an emergency as I thought it was. He gave me a lot of information about the water in our basement and advised me to call him if it happens again after a heavy rain. He also checked out and cleaned my gutter while he was there."

Basement Waterproofing FAQs, answered by experts

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

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.

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all.
