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."

FAQs for foundation repair projects in Grantham, NH

If foundation problems are not fixed, not only do repairs eventually become very costly, but it can lead to structural damage to the house above. Eventually, if the foundation problems are allowed to persist, the foundation walls can cave in or collapse. That’s after other issues like flooding and mold have likely been allowed to develop. Although not all cracks are structural problems, some can be and even if they start out small, they can develop into major problems. The earlier foundation problems are discovered and fixed, the lower the cost to repair will likely be.

Yes, foundation repairs are worth the cost at any stage to avoid a dangerous living condition. A failed foundation can lower the value of your home by up to 20%. Whether it’s the smallest problem like a thin crack less than ⅛-inch wide, a horizontal crack, a crack letting water flow through, or a wall bowing inward, repairing foundation problems as soon as possible is worth the cost. Sometimes a temporary fix can be applied until you have the budget to completely fix the problem, but the longer the problems persist, the more costly repairs may be.

The most common first signs of foundation issues include: 

  • Cracks in the foundation walls that grow

  • Signs of moisture or water leaking through cracks in the foundation

  • Standing water in the basement

  • Sagging floors or walls

  • Cracked walls in upper floors

  • Doors and windows that don’t close properly anymore

Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.

If you’re noticing signs of foundation issues, the first step to fixing a foundation problem is to hire a foundation repair inspector. They will determine the problem, the cause, and the severity before recommending a course of action to repair the foundation. The method for fixing foundation problems depends on the problem and what options are available. A few possible solutions include:

  • Epoxy injections

  • Mudjacking

  • Piers made of steel or concrete

  • Jacks 

  • Hydraulic piers

  • Carbon or steel reinforcement strips

  • Waterproofing materials
