"Very pleased with Mastercraft! Would highly recommend them to anyone who needs waterproofing. Our basement had a small foundation leak and Mastercraft found the exact area it was leaking from. Their work is impeccable they cleaned everything so well it was hard to tell they had to dig around the foundation. Very friendly and so nice to work with them. Thank you Mastercraft!"

"They did a great job. They were able to use a small pump to pump the waste water out before replacing the broken pump. The other company wanted us to pay for a pump truck costing $600 before giving the estimate."

Basement Waterproofing questions, answered by experts

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.

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, 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.

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.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.
