"Fast Estimate , had many estimates from other companies and Waterproofing One was the best price for Us , Joe was very confident and knowledgeable and gave Us good suggestions for our leaking basement, the crew that installed the French drain inside were great, install looks very professional. I figured we’d have a mess to clean up after the install understandably. But wow they did an incredible job cleaning up afterwards. Not a speck, they even spent time cleaning off the driveway and front lawn. We have been through one major rain storm since the install and not a drip of water. So far so good , we are getting an expected 3” in the next 24 hours and it’s a relief to know I don’t have to stress about rain storms anymore!"

"We had a great experience with Basement Gurus. Their team completed waterproofing work in our basement and was professional, knowledgeable, and thorough throughout the entire process. They took the time to explain the work, answered our questions, and made sure everything was completed properly. We appreciate their attention to detail and the peace of mind the completed waterproofing has given us. We would definitely recommend Basement Gurus to anyone in need of quality basement waterproofing services."

"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."

"Sebastian and his team at Perfect Dry were amazing to work with. They waterproofed the basement and then refinished it- creating walls, doors, a staircase, flooring, and painting the ceiling and walls. As a person with not much experience in this area, Sebastian explained everything thoroughly, and all of my expectations were exceeded. Sebastian came back very quickly to adjust a small issue I had with one of the doors about two weeks after the job was complete. Sebastian is very trustworthy and did a beautiful job refinishing my basement. I would hire him again and recommend anyone do the same!"

Basement Waterproofing FAQs, answered by experts

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

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.

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.

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

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.
