"We had 4 basement waterproofing companies come into our home to do an assessment of our basement. We are updating our home and finishing our basement. Although we only had occasional and minor water leaks we wanted to protect our investment. Our time with Mike, Jason, and the rest of the team was professional and informative from the first moment. They were responsive with our estimate, fair with their pricing, and willing to answer our questions along the way. The crew arrived on time and ready to get the project started. We had a couple of large items that we needed help moving and they assisted so that we could keep the basement clean. The work that was performed was done so with care. The basement was kept as clean as possible, and our input was taken into consideration along the way. Hands down thankful for the experience and piece of mind that we now have."

"Erick is a truly good man who stands by his word/price. I had two bathrooms remodeled and I am thrilled with the end result. Erick made sure that any inconvenience to my family was minimal and at the end of every day their clean up incredible. After getting three other estimates, I had Erick come over to estimate the price and his price was 20% lower than some of the other estimates. Erick is my go to contractor, I trust him and I intend to have him do some more work this spring. Feel safe hiring Erick, you will not be sorry."

Basement Waterproofing questions, answered by experts

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.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

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.

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.
