Matt Clark's Northern Basement Systems, locally owned and operated, is the leading basement waterproofing, crawl space moisture control, and foundation repair contractor in Vermont, New Hampshire, & Essex and Clinton County NY. We are accredited with the Better Business Bureau and maintain a consistent A+ rating. We offer quality basement & foundation work while providing outstanding service to each and every one of our customers.

"I strongly caution anyone considering doing business with this company. I gave them a deposit of $4,428.65, and when I canceled a week later they kept almost $900 of it even though my service was not for another 6 weeks. You do sign a very simple, clearly stated document that says, “Should you cancel beyond three business days, you understand your deposit is non-refundable. Northern Basements may choose to refund depending on cancellation circumstances.” I fully acknowledge that I canceled a few days outside that window, but I hoped an honest company that cares about customers and referrals would choose to provide a full refund. I am a sucker for hoping that. They chose to risk my impression, referral and review for $885.53. If nothing else comes out of this, I hope everyone reading at least goes in knowing that this statement on their contract is a real threat and your deposit is hostage. Even Airbnb’s offer full refunds on deposits within just a few days of people’s arrival date. 3 days to cancel with service not scheduled for 6 weeks out, “C’mon man.” No materials were used. No service workers’ time was taken. The manager justified the 20% withholding as credit card fees, restocking fees, time and resources for the estimate, and administrative fees. I wholly accepted responsibility for the credit card fees and time of Paul, the gentleman who performed the assessment, and I offered to settle at 10%. I still believe any reputable company would have provided a full refund at this point in a project, or at most deduct the credit card fees, because nothing more went into this beyond what would have normally been a free estimate. The further arguments the manager made for the additional fees were the scheduling of their team and allocation of materials for my project. Complete nonsense, especially when the project was not set for 6 weeks away. Because they had my deposit hostage, they had control of how much they decided they wanted to keep, it was completely arbitrary, and they kept almost $900 of my money without providing anything. If they wanted to cover their credit card transaction fees, fine, at most 6%, but the rest is absolute robbery. The only solace I can find in this loss of almost $900 now is that I didn’t spend another $13,000 with them. I tried to call Paul after speaking with the manager to ask if he could do me a favor and try to reason with the manager on my behalf because he seemed like a nice enough guy. No answer. No call back. I will never seek out this company’s services again and I will actively discourage others from doing so but, based on my experience, I expect they really don’t care."

Experienced professional - Over 35 years of professional contract work completed. I specialize in structural repairs including Field Stone Foundation - Sill Replacements, Lally Columns, Footings, Beam Replacements - Antiques Bought - that are being listed to be sold. I am fully licensed and insured. Services do not include crack or foundation repair.

"Rene is the best! We reached out to Rene about structural issues on our old home. He responded promptly and scheduled a visit within a few days. He knew just what to do to address some sagging floors and areas of the house that weren't correctly supported. He did all the work himself (he sometimes has his son work with him). I have no idea how he was able to complete all the work on his own, especially pouring new concrete footings in a very small crawl space! He is a machine!!! He is meticulous in his work and really goes above and beyond. He left our basement cleaner than when he started!!! He’s a super nice man and it was a pleasure having him work on our house."

Foundation Repair questions, answered by experts

Minor hairline cracks in your concrete may not look pretty, but they’re often not serious. It’s when concrete cracks are larger—wide enough that you can slide a credit card into it—that you need to worry. If you monitor a crack and can trace its active expansion over time, you’ll definitely want to call in a pro to inspect it and, potentially, repair it. Want to prevent cracks in your garage and driveway concrete in the future? Stay on top of sealing. Here’s how to seal your concrete garage floor and driveway.

Yes, a house can collapse from severe foundation problems if left unchecked, which is why it’s so important to carry out routine foundation inspections and call for repairs at the first sign of an issue. Foundation cracks often take years to get to the point where your home is at risk of collapsing. Implementing a solution quickly, even if your issue seems minor, is always worthwhile.

Foundation problems are costly to repair, but if you already own the home, you can either handle the issues or allow the property to (literally) sink into disrepair. The opposite is true when buying a home. Walk away if the seller refuses to lower the asking price once foundation issues are exposed or if they refuse to handle the problems before the completion of the sale.

Yes, foundation repairs are worth it if you have a significant problem or see signs that could worsen if not dealt with. If your foundation fails, your home can lose up to 20% of its value. Protecting your home from serious structural damage and avoiding more costly repairs later is well worth the money.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.
