"Our house was built in the 1890's. The foundation is stone with multiple generations of mortar in various states of disrepair. Our original plan of interior foam insulation was disrupted by some dramatic seepage on the north side of the foundation. Northern Basements came to provide us with a few options for repair. The diagnostic visit was very informative and the estimates reasonable. We chose the exterior drain option and sent in our deposit. The team that completed the work was amazing in what they accomplished and their very professional demeanor. We also purchased a dehumidifier system from Northern Basements. One year later all systems have worked very well. The basement is dry and we have had no other issues.

"Gage has been excellent to work with. We will hire him any time we need something in the future. The work site is always clean, the new install always looks tidy. He has installed a water filter, fixed several leaks in old plumbing, replaced hose bibs, worked on our booster and expansion tank, replaced fixtures. It's always great work."

Foundation Drain Installation FAQs, answered by experts

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

A grinder pump is a major investment for homeowners and business owners alike. Protect this investment by choosing a reliable and reputable contractor to source the pump itself, install it, and outsource any additional work. Research local sewage system contractors ahead of time to ensure they have the appropriate insurance and licensing. You should also perform a fairly thorough online search to get a feel for the company’s professionalism by reading reviews.

Finally, give them a call to discuss the project. A good technician will be more than happy to get into specifics regarding both the installation process and the pricing.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Installing a sump pump takes a bit of know-how, but it is possible to do it yourself. You’ll need to familiarize yourself with details like where sump pump water goes to avoid creating new flooding risks. If you’re doing the work yourself, it’s recommended to bring in a pro for a quick inspection afterward so you can be sure your home is protected from any water damage concerns.

In most cases, standard homeowners insurance policies do not cover damage from a sump pump failure or overflow. Coverage for water damage is often limited to sudden, unexpected events like a burst pipe that was not caused by negligence. To be covered for sump pump issues, you will likely need to purchase a specific rider, endorsement, or additional water backup insurance. If your insurer offers this type of coverage, they may require proof that your sump pump is regularly maintained.
