How To Choose a Foundation Repair Company

You need a good foundation repair contractor to properly assess issues and make appropriate repairs. Do your research and focus on these factors when selecting the right company.

Experience

Look for a local foundation repair provider with comprehensive experience fixing all types of foundations. It should have specialized knowledge of the latest repair methods and materials. Ask how long a provider has served your area.

Reputation

Thoroughly reading online reviews, checking the Better Business Bureau, and getting local references helps verify that a company consistently delivers top-notch workmanship and great service. Pay attention to any complaints about shoddy repairs or poor service.

Licensing and Insurance

Only hire providers that are properly licensed, bonded, and have both liability and workers compensation insurance. There are no state-level licensing requirements for general contractors in New Hampshire, although a contractor may need to get licensed or registered to work with plumbing, asbestos, septic systems, and more. Be sure to check with your local government to learn if there are any contractor licensing requirements at the city or county level. Contractors may have to meet additional requirements to do certain concrete work.

Warranties

Choose a company that offers transferable warranties of at least 10 years, ideally lifetime guarantees, to back their foundation repairs. This demonstrates that they stand behind the quality of their repairs and offers protection if future issues arise.

Questions To Ask Foundation Repair Companies

As part of your research into foundation repair providers, get detailed answers to questions such as:

  • Can you provide a cost estimate and project scope in writing? Make sure to get quotes in writing to protect yourself from unexpected expenses.
  • What do you see as the likely cause of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide unclear answers may be attempting to bill you for extra work.
  • What financing options do you have? Many providers offer payment plans for larger foundation projects.
  • How long will the repairs realistically take? Look for providers that provide reasonable estimates.
  • What repairs do you recommend for this situation, and why? Your contractor may offer options such as wall anchors, steel piers, and carbon fiber. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What type of guarantees are provided? Trustworthy providers will offer warranties of minimum 10 years on labor and materials.

Thoroughly evaluating foundation repair companies will help you locate the right one for you. Providers that can thoroughly answer these questions will likely offer long-lasting, high-quality repairs. Swiftly fixing foundation issues helps prevent future structural damage.

Frequently Asked Questions About Foundation Repair in Merrimack, NH

There are a variety of signs that your foundation is in need of repair. These might include:

  • Visible crumbling or cracks in your foundation
  • Uneven ground-level or basement floors
  • Bowing, buckling, or cracked walls
  • Door frames or window frames that are skewed or tight
  • Cracks in your basement floor
  • Cracks in your driveway

On average, Merrimack homeowners spend about $3,169 on foundation repair. The cost of foundation repair is based on several factors. Things like the extent of the damage, the size of your home, and the type of repair needed will all play a part. The best way to determine how much a job could cost is to contact a local foundation repair expert and schedule a free inspection and estimate.

The primary 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 required. The price of stabilization varies similarly. This process fixes bowing walls by reinforcing them with carbon fiber or steel strips, and the total cost will depend on the material chosen and how many strips are used.

Lastly, waterproofing is an overarching term for a number of jobs designed to stop water from getting into your foundation or basement. This can include exterior waterproofing, interior waterproofing, or both, and costs can vary widely. We recommend contacting a waterproofing specialist if you think your foundation needs waterproofing.

When constructing a new house, have a soil report completed. A soil report will contain information about how well the soil on a given piece of land can support a foundation, and can provide you with a heads-up about any potential future problems. If you have concerns about an existing house, a few hundred dollars will cover an inspection and report by a structural engineer. They can point you to any issues that could use some attention, and give you advice on avoiding future problems.

It's also important that the moisture around your foundation is appropriate. As Merrimack sees more rain than many other places, keep an eye on your gutters and landscaping to make sure too much water isn't getting into your soil or foundation. Also, be on the lookout for leaky pipes or gutters and repair them promptly.

Permits are needed for most foundation repairs, but acquiring one isn't your responsibility. Your foundation repair provider should obtain the permit and all other documents required in Merrimack, and should be able to explain the process and/or provide the documents before starting work.

You might not want to spend money hiring someone for a seemingly small foundation repair. However, it's always a smart idea to consult a professional. This helps you avoid more expensive issues down the road. You may be able to fix small hairline cracks yourself, but it's always good to get an expert opinion first.

We recommend that you do not put off foundation repairs. Minor issues may have an underlying cause that could lead to numerous future problems, and it's best to get ahead of the issue as soon as possible. A small and moderately costly problem now could turn into a large and expensive one in the future if left untreated.
