"Paul Swann evaluated our foundation problem and referred us to an engineer who provided a detailed repair plan. Unfortunately, the nature and scope of the proposed repair plan was outside the parameters of what Northern Basement System's themselves could provide. We appreciated their honesty and have been looking for a contractor to take on the project."

"Eric and his crew are knowledgeable, prompt, courteous, reliable, and hard-working. Eric listened to my requests, offered helpful guidance, and did a great job. He excavated a trench through a difficult, rocky area; installed electrical conduit; and removed a section of concrete pad for a renovation project. Highly recommend!"

Im a military veteran looking to build my relationship with the community while building trust through my work. Ive worked with companies from corporate to local levels and have watched people get taking through loop holes for basic repairs by being offered the easy replacement option. I love learning new things about how houses were built and ways I can improve the living conditions for the homeowner. \n\nIve done work for affordable housing servicing hundreds of residents to helping customers with growing visions. Being upfront and being honest of all work and pricing is key to proper communication and building the relationship between customer and business. \n\nI strive to perform at a 5 star level and achieving your overall goal.

"When I first called, I was surprised at how quickly they returned my phone call to set up an estimate. He was able to come over the next evening to check out our basement. He was punctual and provided us information about what would need to be done. He stated that he would provide us with an estimate that evening. I waited, but the estimate never came. I called the following week to see the status of the estimate. They stated that they were busy, but I should have it by now and would email it ASAP. After a second week, I called again. They said they would get it to me again. After the third week, I called again and was told the same thing. I gave up at that point and contacted someone else, who will be fixing the basement tomorrow. It's been over a month now and never received an estimate for the work. I understand that it's a busy time of year, but was disappointed to never get the estimate and didn't feel like I should have to pester them for it.

"I was extremely pleased with the work Bert and John did for me. They are extraordinary representatives of Bellavance Land Works. Bert works that excavator like a precision instrument. His work is absolute perfection. I was floored by how great it looked when he was finished. His co worker John went above and beyond what the work required. He stayed busy tidying up and finding minor projects to help with while the excavator was in use. Both Bert and John are super nice to have working at your home. They showed up on time, got right to work and left my yard spotless and me extremely happy. Not kidding. Hire these guys. You will be glad you did!"

"WOW! Their man Raymond came and assessed the work we wanted to have done. He was refreshingly honest and directed us to another business more suited for what we needed done. He was courteous, helpful and very knowledgeable. May hire them in the future!"

Foundation Drain Installation FAQs, answered by experts

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.

Installation typically takes 1-2 days, depending on the scope and site preparation.

French drains, sump pumps, and exterior waterproofing systems are common options. Choose one that best suits your property’s needs.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

Sump pumps remove excess water from the lowest point of your home, which prevents flooding. When a sump pit fills with water, a sump pump pushes that water outside of the basin and into an exterior discharge pipe. From there, the water flows away from your home, so it doesn’t damage your foundation.
