"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

To maintain an outdoor structure, perform regular inspections for damage, leaks, and weak joints. Clean the structure regularly, treat or repaint wood surfaces for weather resistance, and reinforce any weak joints to prevent deterioration and ensure its longevity.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
