11 Best Foundation Companies in Portsmouth, NH

On average, Portsmouth homeowners pay around $2,802 for foundation repair, although the actual cost will vary depending on several factors. The fastest way to estimate the cost of your specific project is to get quotes from a few local foundation repair companies. Your total cost will be influenced by things like the type of the repair(s) and the size of your house.

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 complete any repairs necessary to remedy cracks or leaks. Costs will vary based 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 used. The price of stabilization varies similarly. This process reinforces bowing walls with steel or carbon fiber strips, and the cost will depend on the material and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs that help stop 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 interested in waterproofing your foundation.

One way to protect your foundation is to make sure it gets the proper level of moisture. Portsmouth 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 promptly identify and fix any leaking pipes or gutters.

If you have any concerns about your foundation, you can call 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 additional steps to further protect your foundation. Lastly, if you're constructing a new house, be sure to have a soil report done. This can provide information regarding how well the soil on your property will be able to support a foundation, and can highlight any potential future problems.

A permit is normally required for foundation repair, but acquiring one should not be your responsibility. Your foundation repair provider should obtain all the permits and other documents required in Portsmouth, and should be able to explain the process and/or provide the documents if asked.

While some foundation problems may seem small and not worth the cost to fix, when left untreated, they can lead to larger and more expensive problems later on. Foundation issues can also have underlying causes which are not clear until after a professional inspection. It's important to fix these underlying issues as soon as possible. For these reasons, we advise against procrastinating on foundation repairs.

Foundation repair, particularly extensive repairs like basement waterproofing, should last a long time. This is particularly true if you use a reliable company. By solving systemic issues with your foundation, or reinforcing key areas, you reduce your risk of future problems.
