"I had Ameri-Dry Waterproofing come to my house to inspect a water problem we

were having in our basement.  We found the inspector, Barry, to be very

knowledgeable and very thorough in his inspection.  He explained everything

to us and answered all of our question, which we had many.  At the end of

the inspection we all sat down and went over our goals and expectations.  We settled on the

Ameri-Dry drain system and found the price to be fair.  The full warranty

was the clincher for us.  They installed the system in less than a week and

I must say the men were very courteous.  They worked very hard and finished

the job in under four days.  The foreman, Barry, ran his crew very efficiently.

Everyone had their job and they performed them to my full satisfaction.

Even though we had dust they cleaned up nicely. I highly recommend Ameri-Dry

and would hire them again if I ever had the need.

Basement Waterproofing FAQs, answered by experts

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

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.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.
