Basement waterproofing and foundation repair company. Family owned since 1957 with over 300,000 dry basements. Free consultations. Lifetime warranties available. Award winning company.

"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"

basement waterproofing

"We are so impressed with Everseal. They installed a sump pump and interior drainage tiles in our basement in March of 2021. The job took only four days. The employees worked extremely hard to install the pump, interior drain tiles and window well drains. The young men, who removed debris from the basement in buckets and returned with fresh cement, literally ran in and out of the house to complete the job. They were amazing. They then brought their own hose to wash down any residue on our sidewalk and driveway. They took great care to keep the dirt and dust to a minimum. As they broke up the concrete floor, they used a powerful exhaust fan that vented to the outside through one of our basement windows. For additional protection, they wrapped the furnace with plastic sheets and hung plastic sheets around the basement enclosing the work area. They then made a tunnel with plastic from the basement door to the upstairs front door. Yes, there was dust that reached the upstairs. But, without their careful concern for our home, it could have been much worse. After the project was finished, we washed our walls upstairs and they were fine. The dust that reached the upstairs was easily cleaned.   They were price competitive and always went the extra mile to answer our questions.  A month after the installation, they returned to install a gasket and aluminum strips around the flange in the area where we do occasional woodworking. They did not charge for this service. And, they kept a vacuum operating to capture the dust while they were drilling the small holes in the concrete. The results look great. They also removed their shoes before entering our home and then wore booties to keep the dirt in the basement. Again, it is their attention to detail that sets them apart from others.  Everseal is a top notch company and deserves an A++ rating!"

Basement Waterproofing questions, answered by experts

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.
