"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

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
