"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 you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.
