11 Best Foundation Companies in Londonderry, NH

On average, Londonderry homeowners pay around $2,802 for foundation repair, although the cost will depend on several factors. The easiest way to get an estimate for the cost of your specific project is to solicit quotes from a handful of local foundation repair companies. Your total cost will be determined by things like the size of your house and type of repair(s) needed.

The primary types of foundation repair are crack repair, leak repair, underpinning, stabilization, and waterproofing.

Crack repair and leak repair are exactly as they sound: your foundation contractor will perform an inspection and complete any repairs necessary to remedy cracks or leaks. The price will vary depending on the size and cause of the problem.

Underpinning, also called piering or leveling, is the process of leveling your foundation by underpinning it with large concrete piers. The amount you can expect to spend depends on how many piers are required. The price of stabilization varies similarly. This process reinforces bowing walls with steel or carbon fiber strips. The total cost will depend on the material chosen and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs designed to prevent water from getting into your foundation or basement. This can involve exterior waterproofing, interior waterproofing, or both, and costs can vary widely. We recommend contacting a waterproofing specialist if you're planning to waterproof your foundation.

One way to protect your foundation is to make sure that it has the right amount of moisture. Londonderry sees more rain than many places, so be sure that your gutters and landscaping are arranged to prevent too much water from collecting near your foundation. Additionally, make sure that you quickly identify and fix any leaking pipes or gutters.

If you think there may be any problems with your foundation, you can contact a structural engineer for an evaluation. This will run you a few hundred dollars, but the engineer's consultation can provide you with a list of things to be aware of as well as steps you can take to further protect your foundation. Finally, if you're building a new home, be sure to have a soil report done. This report provides information regarding how well the soil on your property can support a foundation and highlights any potential future problems.

Your foundation repair provider should be the one to get the permits. You can request that the company provide a detailed explanation of the steps in its process and to see the permits and paperwork it has assembled to verify that everything is properly authorized per Londonderry regulations.

If your foundation needs waterproofing, you'll start to notice signs like uneven floors, white powder or spots on your walls, basement flooding, discoloration or odors, hairline cracks, or signs of fungus, mold, or mildew.

You might not love the idea of spending money to hire someone for a seemingly small foundation repair. However, it's always in your best interest to consult a professional. This way, you can avoid potential future issues that could be even more expensive. It may be possible to fix small hairline cracks yourself, but it's always good to get an expert opinion first.
