"Outstanding job by H&R in the waterproofing my basement on February 16. It was Providence as 10 days later a water line in front of my house burst sending thousands of gallons of water cascading toward my house and against the walls of the basement that were waterproofed. The internal french drain and sump pump performed as described by H&R and my basement stayed dry as a bone. We would definitely recommend this business. H&R stands far above other competing basement waterproofers in their honesty and work."

"I recently hired Advanced Basement Solutions after my basement had sustained multiple floods. They sent out a knowledgeable inspector who thoroughly assessed the situation and provided me with several options to address the issue. The quote for installing an internal French drain was very reasonable, and the service that followed was exceptional. A team of 7 workers arrived shortly after and completed the entire job in just one day. They left everything spotless, and since then, my basement has weathered several heavy rains without a single drop of water. I highly recommend Advanced Basement Solutions for their professionalism and efficiency in French drain installation."

Basement Waterproofing FAQs, answered by experts

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Yes, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.

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.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.
