11 Best Foundation Companies in Durham, NH

On average, Durham homeowners pay roughly $3,168 for foundation repair, although the cost will vary widely depending on several factors. The best way to get an estimate for the cost of a specific job is to ask for quotes from a handful of local foundation repair companies. The total price will be influenced by things like the size of your house and type of repair(s) needed.

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

Crack repair and leak repair are what they sound like: your foundation contractor will perform an inspection and take necessary measures to remedy cracks or leaks. Costs will depend on the size and cause of the problem.

Underpinning, also called leveling or piering, is when a contractor levels your foundation by underpinning it with large concrete piers. The price will be based on how many piers are required. The price of stabilization varies similarly. This process involves fixing bowing walls by reinforcing them with carbon fiber or steel strips, and the cost will depend on the material chosen and how many strips are used.

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

When caring for your foundation, you should make sure that it gets the right amount of moisture. Durham 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. You should also be sure to promptly identify and fix any leaking gutters or pipes.

If you have any concerns about your foundation, you can contact a structural engineer for an evaluation. This will run you a few hundred dollars, but the consultation can provide you with a list of things to look out for as well as more ideas to help you further protect your foundation. Finally, if you're building a new home, be sure that you have a soil report done. This can provide information about how well the soil on your property will be able to support a foundation, and can highlight potential future problems.

Foundation repair usually requires a permit, but acquiring one should not be your responsibility. Your foundation repair provider should get the permit and all other documents required in Durham, and should be able to explain the process and/or provide the documents before starting work.

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

Foundation repairs carried out by a trustworthy company should last a long time. Bigger and more extensive repairs, like basement waterproofing, can be involved and expensive, but they do a lot in terms of reducing the risk of future issues.
