"We hired Mike to do our basement waterproofing prior to finishing our basement. They 1) repaired a leaking wall crack using a fill and carbon fiber seal, 2) replaced our original sump pump, 3) installed a full perimeter french drain system, 4) installed a second sump pump, and 5) a thermal armor wall cover on all walls. Overall, we were quite pleased with the negotiations, timing, install process, and finished product. Would definitely recommend giving Mike at Aqua Dry a call for basement waterproofing."

"We had Peter and his crew from Aqua-Dry come out and replace our basement French drain, and sump pump and waterproof the cinder block walls. We have had no issues since. Our basement was done in the Spring of 2016. I have recommended Aqua-Dry to multiple friends. Peter stands by his work."

"I was referred to this company through HomeServe. I had a severely damaged basement pipe that ran to a second bathroom of ours. Not only did Paradigm Plumbing figure out the problem on the spot, they were back in 24 hours with everything they needed in order to complete the job. A problem that was bothering me for months they had figured out in 24 hours. I could not be happier with them. They have incredible communication, were very timely and protected everything that was outside of the bathroom they worked on. I can't recommend these guys enough."

Basement Waterproofing FAQs, answered by experts

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.
