How To Choose a Foundation Repair Company

Hiring a qualified foundation repair company 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

We suggest choosing a local foundation repair provider with a well-established track record of fixing various types of foundations. These companies should have deep knowledge of the latest materials and techniques. Ask how many years a provider has served your area.

Reputation

Spend time checking online reviews, browsing the Better Business Bureau, and asking for local references. This will help verify that the company consistently delivers quality work and professionalism. Take note of any complaints mentioning poor service or faulty repairs.

Licensing and Insurance

Choose a company that has the right licenses, bonds, and coverage plans for liability and workers' compensation. In Missouri, there is no state-level general contractor license (although an individual may hold a professional engineering license from the Division of Professional Regulation). General contracting requirements are handled at the city, county, or municipal level. You can verify a company's business license on this website. Contractors may have to meet additional requirements to do certain concrete work.

Warranties

Pick a company that offers transferable warranties for a minimum of a decade and, if possible, lifetime guarantees to fully back its work. This displays faith that their repairs will be high-quality and long-lasting and provides protection if problems come up later.

Questions To Ask Foundation Repair Companies

When comparing potential foundation repair companies, be sure to ask detailed questions such as:

  • What options do you have for financing? Many providers offer payment plans for larger foundation projects.
  • Realistically, how long will the repairs take to complete? Look for companies that provide reasonable estimates.
  • What type of guarantees are provided? Trustworthy providers typically offer warranties of at least 10 years on labor and materials.
  • Can you provide a project scope and cost estimate in writing? Make sure to get quotes in writing to protect yourself from unexpected expenses.
  • What repairs do you recommend for my situation, and why? Your contractor may consider options such as steel piers, wall anchors, and carbon fiber. Asking allows you to compare suggested solutions between companies.
  • 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 vague answers may be trying to bill you for extra work.

Thoroughly evaluating foundation repair companies will help you locate the right one for you. Providers that can thoroughly answer these questions will likely deliver durable, high-quality repairs. Promptly addressing foundation issues helps prevent future structural damage.

Frequently Asked Questions About Foundation Repair in Union, MO

There are several 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
  • Cracked, bowing, or buckling walls
  • Door frames or window frames that are skewed or tight
  • Cracks in your basement floor
  • Cracks in your driveway

On average, Union homeowners pay about $2,451 for foundation repair, although the total cost will vary widely depending on several factors. The best way to get an estimate for the cost of your specific project is to request quotes from a few local foundation repair companies. Your total cost will be influenced 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 exactly as they sound: your foundation contractor will perform an inspection and take necessary measures to remedy cracks or leaks. The price will vary depending on the size and cause of the issue.

Underpinning, also called piering or leveling, is when a contractor levels your foundation by underpinning it with large concrete piers. The price will be based on how many piers are required. The price of stabilization varies similarly. This process reinforces bowing walls with steel or carbon fiber strips, and the total cost will depend on the material and how many strips are used.

Finally, waterproofing is an overarching term for a number of jobs that help prevent water from getting into your foundation or basement. This can involve exterior waterproofing, interior waterproofing, or both, and costs can vary greatly. We recommend contacting a waterproofing specialist if you're interested in waterproofing your foundation.

To protect your foundation, you should make sure that it gets the right amount of moisture. Avoid letting the soil around your Union house become too wet or too dry – make changes to your gutter system to route water away, or water your foundation if it starts to get too dry. Also be sure to promptly identify and fix any leaking gutters or pipes.

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 engineer's consultation can net you a list of things to look out for as well as steps you can take to further protect your foundation. Finally, if you're constructing a new home, be sure to have a soil report done. This report provides information about how well the soil on your property can support a foundation and highlights potential future issues.

Your foundation repair provider should be the one obtaining the permits. You can ask the company to provide a detailed explanation of the steps in its process and to see the paperwork and permits it has assembled to verify that everything is properly authorized per Union regulations.

We strongly suggest contacting your home insurance provider before you start any foundation repairs to figure out what might be covered. Typically, foundation repairs aren't covered by home insurance unless they're to repair damage that was caused by a covered weather event.

The length of time a foundation repair takes varies greatly depending on the kind of repair needed and the size of your home. Most repairs will take anywhere from one to several weeks. Consult your Union foundation repair company for a more specific timeline for your project.
