"Everyone was very professional and courteous. Since they were both waterproofing (installing a sump pump system) and finishing the basement there were two different crews but each one was knowledgeable and took care and time to show me every step they were making. There were a few times where communication from the head office was a little lacking but the team members themselves were great. I would highly recommend their services even though the price tag is quite high."

"Installation was completed ahead of time despite a heavy rain shower. They arrived on time but forgot to bring floor covering. They called and had the covers within an hour. That did not delay the install."

"We had a foundation crack repaired and drainage pipes and sump pump installed. I anticipated the work to be highly disruptive and messy but it was done in a day (double crew) and very clean afterwards. After two months the basement is noticeably drier. Very pleased with the results!"

"The required fix required that outside trenching be done and B-Dry does not do this type of work. The representative was very knowledgeable about the problem and apologized for not being able to solve the issue. Very much appreciated his honesty."

Basement Waterproofing FAQs, answered by experts

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.
