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 conduct research beforehand, focusing on the factors listed here.

Experience

Pick a local foundation repair provider with significant experience fixing all types of foundations. It should have expertise in the latest repair techniques and materials. Ask how long a company has served your area.

Reputation

Reading through online reviews, checking the Better Business Bureau, and asking for local references helps you verify that the company consistently delivers quality work and a great customer experience. Pay attention if you see multiple complaints about shoddy repairs or poor service.

Licensing and Insurance

Only hire companies that are properly licensed, bonded, and have both workers compensation and liability insurance. Throughout Tennessee, contractors must have a Prime (General) Contractor license from the Department of Commerce & Insurance for projects worth over $25,000. In Hamilton, Davidson, Marion, Rutherford, Robertson, Shelby, Knox, Haywood, and Bradley counties, contractors also require a Home Improvement license for home improvement projects between $3,000 and $25,000. While the former requires an exam, the latter does not. Both licenses require proof of insurance. Contractors may have to meet additional requirements to do certain work with concrete.

Warranties

Opt for a provider offering long transferable warranties of at least 10 years, ideally lifetime guarantees, to completely back its foundation repair work. This exhibits belief in the quality and durability of the repairs and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

To compare foundation repair companies, you should ask specific questions such as:

  • What are some likely causes of the problem 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 unneeded work.
  • What type of guarantees are provided? Trustworthy providers will offer warranties of minimum 10 years on labor and materials.
  • Can you provide a complete written project scope and cost estimate? Getting the details in writing helps protect you from unexpected costs.
  • What repair method do you recommend for this specific situation and why? Your provider may offer options such as wall anchors, carbon fiber, and steel piers. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • How long will the repairs realistically take to complete? Look for companies that provide reasonable estimates.
  • What financing options do you have? Many providers offer payment plans for larger foundation projects.

Carefully evaluating 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, long-lasting repairs. Promptly fixing foundation problems helps avoid further structural damage.

Frequently Asked Questions About Foundation Repair in Knoxville, TN

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

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

On average, Knoxville homeowners spend about $2,879 on foundation repair. The total cost of foundation repair is based on a number of factors. Things like the type of repair needed, the size of your home, and the extent of the damage will all help determine the cost. The easiest way to learn how much a job may cost is to reach out to a local foundation repair company and schedule a free inspection and estimate.

The primary types of foundation repair include 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 piering or leveling, is when a contractor levels your foundation by underpinning it with large concrete piers. The amount you can expect to spend depends on how many piers are needed. The price of stabilization is also variable. This process involves fixing bowing walls by reinforcing them with steel or carbon fiber strips. The cost will depend on the material and how many strips are used.

Finally, waterproofing is an overarching term for a number of jobs designed to prevent water from getting into your foundation or basement. This can involve interior waterproofing, exterior waterproofing, or both, and the price can vary greatly. We recommend contacting a waterproofing specialist if you're planning to waterproof your foundation.

When building a new house, make sure that a soil report is completed. A soil report will contain information regarding how well your soil can support a foundation, and can offer you a heads-up about 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. The engineer can alert you to any current problems that need attention, and give you advice on avoiding future problems.

Also ensure that the moisture around your foundation is appropriate, particularly when the weather gets hot. As Knoxville 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. You should also stay vigilant for leaky gutters or pipes and repair them quickly.

Permits are needed for most foundation repairs, but getting one shouldn't be your responsibility. Your foundation repair professional should get all the permits and other documents required in Knoxville, and should be able to explain the process and/or provide the documents if asked.

You should ask your foundation repair professional about this question before beginning any project. Typically, yes, you should be able to remain in your home while foundation work is being done.

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