How To Choose a Foundation Repair Company

Hiring a qualified foundation repair business 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

Pick a local foundation repair provider with significant experience fixing all kinds of foundation problems. It should have specialized knowledge of the latest repair techniques and materials. Ask how long a provider has served your area.

Reputation

Looking through online reviews, checking the Better Business Bureau, and asking for local references helps verify that a company routinely provides good workmanship and good service. Pay attention if you see many 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 apply for 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 work with concrete.

Warranties

Pick a provider that offers warranties of 10+ years that you can transfer to a new owner if you sell and, if possible, lifetime guarantees to fully back its services. This displays faith that their repairs will be high-quality and long-lasting and provides protection should problems come up later.

Questions To Ask Foundation Repair Companies

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

  • What foundation flaws did you identify during inspection that could be causing the issue? The response should have easy-to-understand explanations and solutions. If a provider offers an unclear answer, it may be trying to bill you for unnecessary work.
  • How long will repairs realistically take? Look for companies that provide reasonable estimates.
  • What guarantees do you provide? Reliable companies generally provide labor and materials warranties of at least 10 years.
  • 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 options do you offer for financing? Many providers offer payment plans for larger foundation projects.
  • What repair method would you recommend for this specific situation and why? Your provider may offer options such as wall anchors, steel piers, and carbon fiber. Asking allows you to compare suggested solutions between companies.

Taking time to carefully evaluate foundation repair contractors will help homeowners discover the right company for their needs. A company that can thoroughly answer these questions is likely one that delivers durable, high-quality repairs. Promptly fixing foundation issues reduces the risk of further structural damage.

Frequently Asked Questions About Foundation Repair in Cupertino, CA

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

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

On average, Cupertino homeowners pay roughly $3,287 for foundation repair, although the cost will depend on several factors. The easiest way to get an estimate for the cost of a specific project is to request quotes from a few local foundation repair companies. Your total cost will be affected by things like the type of the repair(s) and the size of your house.

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 repair expert will perform an inspection and complete any repairs necessary to remedy cracks or leaks. Costs will vary based 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 cost will depend on how many piers are used. The price of stabilization is also variable. This process fixes bowing walls by reinforcing them with steel or carbon fiber strips, and the total cost will depend on the material chosen and how many strips are used.

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

To protect your foundation, you should make sure it gets the right amount of moisture, especially in hot weather. Cupertino tends to be a very dry place, so in times of little rain you may need to water your foundation. You should also be sure to promptly identify and repair 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 cost a few hundred dollars, but the engineer's consultation can net you a list of things to be aware of as well as more ideas to help you further protect your foundation. Lastly, if you're constructing a new home, be sure to have a soil report done. This can provide information regarding how well the soil on your property will be able to support a foundation, and can highlight any potential future issues.

Your foundation repair professional should be the one to get 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 confirm everything is properly authorized per Cupertino regulations.

You may not love the idea of spending money to hire someone for what seems like a 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. You may be able to repair small hairline cracks on your own, but it's always in your best interest to get an expert opinion first.

Foundation repairs completed by a reliable company should last a long time. Extensive repairs, like basement waterproofing, can be involved and expensive but do a lot in terms of mitigating the risk of future issues.
