How To Choose a Foundation Repair Company

Hiring a qualified foundation repair contractor ensures you have someone who will inspect the damage thoroughly and make appropriate fixes. It's important to do your research beforehand, focusing on the factors listed here.

Experience

Choose a well-established local company with many years, ideally decades, of experience successfully handling all types of foundation repairs. These providers have specialized expertise using the latest methods and materials. Ask how long a company has served homes in your area.

Reputation

Spend time reading through online reviews, browsing the Better Business Bureau, and requesting local references. This will help confirm that the company consistently delivers good workmanship and great customer service. Take note of any complaints mentioning faulty repairs or poor service.

Licensing and Insurance

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

Warranties

Look for a provider that offers lengthy transferable warranties for a minimum of a decade, or preferably lifetime guarantees, to back its work. This demonstrates faith that its services are top-quality and safeguards you if issues come up in the future.

Questions To Ask Foundation Repair Companies

When examining potential foundation repair companies, make sure to ask in-depth questions such as:

  • What repairs do you recommend for my situation, and why? Your contractor may provide options such as wall anchors, steel piers, and carbon fiber. Asking allows you to compare suggested solutions between companies.
  • Can you provide a complete written cost estimate and project scope? Getting quotes in writing helps protect you from unexpected expenses.
  • What financing options do you have? Providers often offer payment plans for larger foundation repairs.
  • How long will the repairs realistically take to complete? Look for providers that provide reasonable estimates.
  • What warranties do you provide? Reputable providers typically provide labor and materials warranties that last at least 10 years.
  • What are some likely causes of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide vague answers may be trying to bill you for extra work.

Thoroughly assessing foundation repair companies helps homeowners select the ideal match for their needs. A provider that can answer the questions above is likely one that delivers long-lasting, durable repairs. Promptly fixing foundation problems helps prevent further structural damage.

Frequently Asked Questions About Foundation Repair in New Canaan, CT

There are several signs that your foundation is in need of repair. These can include:

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

On average, New Canaan homeowners pay about $2,636 for foundation repair, although the total cost will change based on several factors. The best way to get an estimate for the cost of a specific project is to ask for quotes from one or more local foundation repair companies. The total price will be determined 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 repair expert will perform an inspection and take necessary measures to remedy cracks or leaks. Costs will vary depending on the size and cause of the issue.

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 used. The price of stabilization varies similarly. This process involves fixing 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 intended to prevent water from getting into your foundation or basement. This can include exterior waterproofing, interior waterproofing, or both, and costs can vary greatly. 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 gets the right amount of moisture. New Canaan 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. Also 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 call a structural engineer for an evaluation. This will run you a few hundred dollars, but the consultation can net you a list of things to look out for as well as steps you can take to further protect your foundation. Lastly, if you're building a new house, make sure that you 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 issues.

Your foundation repair expert should acquire the needed permits. You can ask the company to provide a detailed explanation of the steps in its process and to see the permits and paperwork it has acquired to ensure everything is properly authorized per New Canaan regulations.

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

We strongly suggest getting in touch with your home insurance provider before beginning any foundation repairs to figure out what might be covered. In general, foundation repairs aren't covered by your home insurance unless they're to fix damage caused by a covered weather event.
