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 local foundation repair company with extensive experience fixing all foundation types. It should have expertise in the latest repair methods and materials. Ask how long a company has served your area.

Reputation

Researching online reviews, checking the Better Business Bureau, and requesting local references helps you verify that the provider consistently delivers quality work and a great customer experience. Pay attention if you see numerous complaints about poor service or faulty repairs.

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 must have at least four years of related work experience in the last ten years (or be represented by someone who does), must pass both a law and business and a trade exam, and must be bonded. Individuals or businesses that have employees must also have workers' compensation insurance. Contractors may have to meet additional requirements to do certain concrete work.

Warranties

Opt for a provider offering transferable coverage for 10+ years, ideally lifetime guarantees, to completely back its foundation repair work. This exhibits confidence that the repairs will be effective and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

During your assessment of potential foundation repair companies, make sure to ask in-depth questions such as:

  • What exact repair method do you recommend for this specific situation and why? Your provider may consider options such as carbon fiber, wall anchors, and steel piers. Asking allows you to compare suggested solutions between companies.
  • What type of warranties do you offer? Trustworthy providers will offer warranties of at least 10 years on labor and materials.
  • Can you provide a complete written cost estimate and project scope? Getting the details in writing helps shield you from unexpected expenses.
  • What options do you offer for financing? Providers often offer payment plans for larger foundation repairs.
  • 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 extra work.
  • How long will repairs realistically take? Look for companies that provide reasonable estimates.

Taking the time to review foundation repair companies helps homeowners find the ideal match for their needs. A provider that can answer the questions above is likely one that delivers high-quality, durable repairs. Promptly fixing foundation problems helps avoid further structural damage.

Frequently Asked Questions About Foundation Repair in San Diego, CA

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

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

On average, San Diego homeowners pay about $2,665 for foundation repair, although the actual cost will depend on several factors. The best way to get an estimate for the cost of a specific project is to get quotes from a few 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.

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, completing an inspection, and using various measures to remedy leaks or cracks. The cost of these procedures can vary greatly depending on the size and root cause of the problem.

Stabilization reinforces bowing walls by inserting steel or carbon fiber strips. The cost will depend on the material chosen and the number of strips needed. The cost of underpinning also varies. This process, also called piering or leveling, involves leveling your foundation by underpinning it with concrete piers; the cost will depend on how many piers are used.

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

When constructing a new home, make sure that a soil report is completed. A soil report will contain information about how well the soil on a given piece of land can support a foundation, and can provide you with 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. They can point you to any current problems that could use some attention, and advise you on how to avoid future problems.

It's also important that the moisture around your foundation is appropriate, particularly when the weather gets hot. The weather in San Diego 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 gutters or pipes and repair them promptly.

Your foundation repair provider should be the one to get the permits. You can ask the company to provide a detailed explanation of its process and to see the permits and paperwork it has assembled to make sure everything is properly authorized per San Diego regulations.

Foundation repairs can sometimes, foundation repairs can be considered capital improvements if they meet the criteria of an improvement that will add to a home's overall value, prolong its life, or adapt it to new uses. In some cases, making capital improvements helps you qualify for tax breaks. (Speak with your California tax professional to learn more.) This aside, foundation repairs will, in most cases, positively affect the value of your home.

Foundation repair, especially large repairs such as basement waterproofing, should last a long time. This is especially true if you go with a reliable company. By solving systemic foundation issues, or reinforcing important areas, you reduce your risk of future problems.
