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 key factors when selecting the right company.

Experience

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

Reputation

Looking through online reviews, checking the Better Business Bureau, and asking for local references helps verify that a company consistently provides good workmanship and great customer service. Pay attention if you see multiple complaints about faulty repairs or poor service.

Licensing and Insurance

Only hire providers that are properly licensed, bonded, and have both workers compensation and liability insurance. In California, general contractors are required to be licensed by the Contractors State License Board in order to work on projects valued at $500 or more. To obtain a license, an individual needs to have at least four years of related work experience in the last decade (or be represented by someone who does), must pass both a law and business and a trade exam, and must be bonded. If an individual or business has employees, workers' compensation insurance is also required. There may be additional requirements for contractors to do certain work with concrete.

Warranties

Choose a provider that offers transferable warranties of at least a decade, 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

To compare foundation repair professionals, you should ask detailed questions such as:

  • What warranties do you provide? Reputable providers usually provide labor and materials warranties of at least 10 years.
  • Can you provide a complete written project scope and cost estimate? Getting quotes in writing helps protect you from unexpected costs.
  • What foundation defects did you identify during inspection that may be causing the issue? The response should have easy-to-understand explanations and solutions. If a provider offers an unclear answer, it may be attempting to bill you for unnecessary work.
  • What options do you offer for financing? Providers often offer payment plans for larger foundation repairs.
  • Realistically, how long will the repairs take to complete? Look for companies that provide reasonable estimates.
  • What 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.

Taking time to carefully evaluate foundation repair contractors will help homeowners find the right company for their needs. A company that can thoroughly answer these questions is likely one that provides long-lasting, high-quality repairs. Promptly fixing foundation issues helps prevent further structural damage.

Frequently Asked Questions About Foundation Repair in Diamond Bar, CA

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

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

On average, Diamond Bar homeowners pay about $2,705 for foundation repair, although the cost will change based on several factors. The best way to get an estimate for the cost of a specific job is to request quotes from a handful of local foundation repair companies. The amount you pay for a job will be influenced by things like the type of the repair(s) and the size of your house.

Types of foundation repair include leak repair, crack repair, stabilization, underpinning, and waterproofing.

Leak repair and crack repair involve a technician coming to your home, performing an inspection, and using various repair techniques to remedy leaks or cracks. The amount you spend will vary greatly depending on the size and root cause of the problem.

Stabilization reinforces bowing walls by inserting carbon fiber or steel strips. The amount you spend will depend on the material used and the number of strips needed. The cost of underpinning also varies. This process, sometimes referred to as leveling or piering, involves leveling your foundation by underpinning it with concrete piers; the cost will be based on how many piers are needed.

If you're looking to waterproof your foundation or basement, we suggest finding a waterproofing specialist. This process might include indoor waterproofing, outdoor waterproofing, or both.

If you're constructing a new house, make sure that a soil report is completed. This report contains information regarding how well your soil can support a foundation, and can offer you a heads-up about potential future problems. If your concerns are about an existing home, for a few hundred dollars, you can get an inspection and report by a structural engineer. They can point you to any things that could use some attention, and advise you on how to avoid future problems.

Also ensure that the moisture around your foundation is at an appropriate level, particularly when the weather gets hot. The weather in Diamond Bar tends to be very dry, which means that at times you may need to water your soil and foundation. You should also stay vigilant for leaky pipes or gutters, so you can get them repaired quickly.

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

In general, your home insurance won't cover foundation repairs, except for those done to repair damage caused by a covered weather event. It's a good idea to talk to your home insurance company before beginning any foundation repairs.

Foundation repair, particularly large repairs such as basement waterproofing, should last a long time. This is particularly true when you hire a reliable company. By solving systemic foundation issues, or reinforcing key areas, you lower the risk of future problems.
