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. Basement Waterproofing Sump Pump System Crawl Space Repair Foundation Repair Concrete Leveling and Sealing Mold Problems.

"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."

We've been serving York County and the Seacoast for over 25 years. Fully insured. All work is warrantied. We take half the quote amount up front and half upon completion. We will also give as many recommendations from brick yards and customers as needed.

"One word: Don't. They replaced the top 6' of our chimney about 7 years ago as well as parging and sealing all of our chimneys and the new chimney is literally falling apart in chunks, the joints are seeping water, and the parging is flaking off. Besides that, while these two jokers were here (and we weren't) our neighbor told us that they were arguing and throwing chunks of concrete at each other. We also found that rather than haul the old chimney pieces away they hid them in the brush beside our lawn. Also, forget about a warrantee. That is B.S."

Basement Waterproofing questions, answered by experts

It’s not safe to live in a house with water damage until a trained professional gives you the all-clear to return. Mold can grow within one to two days after water damage and weaken your home’s structural integrity. Always have your home inspected after water damage to ensure it’s safe to live in.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

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.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.
