How To Choose a Foundation Repair Company

Working with a qualified foundation repair business is important for accurately evaluating the damage and completing repairs correctly. We recommend focusing on these main factors.

Experience

Look for a reliable local foundation company with significant experience in successfully fixing all foundation types. Technicians should have extensive experience with current repair materials and methods. Contact the company to ask how long the business has served your community.

Reputation

Reading through online reviews, checking the Better Business Bureau, and requesting local references helps you confirm that a company consistently delivers good workmanship and a great customer experience. Pay attention if you see numerous complaints about shoddy repairs or poor service.

Licensing and Insurance

Make sure any company you hire has the right licenses, bonds, and coverage for liability and workers' compensation. You typically want to look for a general contractor license. In Connecticut, this may be referred to as a Home Improvement Contractor license. These licenses are controlled by the Department of Consumer Protection. Contractors may have to meet additional requirements to do certain concrete work.

Warranties

Pick a company that offers warranties of 10+ years that you can transfer to a new owner if you sell and, if possible, lifetime guarantees to fully back its work. This displays confidence that the company's work is top-notch and provides protection if problems come up later.

Questions To Ask Foundation Repair Companies

During the process of selecting foundation repair providers, get detailed answers to questions such as:

  • What exact repair method would you recommend for my specific situation and why? Your provider may consider options such as steel piers, carbon fiber, and wall anchors. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • 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 unnecessary work.
  • Can you provide a project scope and cost estimate in writing? Make sure to get quotes in writing to protect yourself from unexpected expenses.
  • Realistically, how long will repairs take? Look for companies that provide reasonable estimates.
  • What warranties do you provide? Reliable companies typically provide labor and materials warranties that last at least 10 years.
  • What options do you offer for financing? Providers often offer payment plans for larger foundation repairs.

Thoroughly assessing foundation repair companies helps homeowners find the ideal match for their needs. A provider that can answer the questions above is likely one that provides high-quality, durable repairs. Swiftly tackling foundation problems helps avoid further structural damage.

Frequently Asked Questions About Foundation Repair in New Haven, CT

There are a variety of signs that your foundation needs repairs. These might include:

  • Visible crumbling or cracking of your foundation
  • Uneven ground-level or basement floors
  • Buckling, bowing, or cracked walls
  • Window frames or door frames that are skewed or tight
  • Cracks in your basement floor
  • Cracks in your driveway

On average, New Haven homeowners pay about $3,012 for foundation repair, although the cost will depend on several factors. The easiest way to estimate the cost of your specific job is to ask for quotes from a few 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 what they sound like: your foundation repair expert 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 the process of leveling your foundation by underpinning it with large concrete piers. The price will be based on how many piers are required. The price of stabilization is also variable. This process fixes bowing walls by reinforcing them with carbon fiber or steel strips. The cost will depend on the material and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs designed to stop water from getting into your foundation or basement. This can include interior waterproofing, exterior waterproofing, or both, and the price 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 that it gets the right amount of moisture. New Haven 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 repair 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 engineer's consultation can provide you with a list of potential concerns as well as more ideas to help you further protect your foundation. Finally, if you're building a new home, make 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 any potential future problems.

A permit is normally required for foundation repair, but applying for one shouldn't be your responsibility. Your foundation repair provider should put together all the permits and other documents required in New Haven, and should be able to provide the documents and/or explain the process before starting work.

You may be able to handle small hairline cracks yourself, but in general, you should consult a professional before beginning any kind of foundation work. While you may balk at the idea of paying someone for a task you feel like you can handle yourself, mistakes made during foundation repair can be even more costly in the future.

Foundation repairs undertaken by a trustworthy company should last a long time. Large repairs, such as basement waterproofing, can be involved and expensive, but they are very helpful in mitigating the risk of future issues.
