How To Choose a Foundation Repair Company

Conduct research before beginning your foundation repair project in order to find the most qualified foundation repair provider. Here are the main factors to consider.

Experience

Look for a reliable local foundation company with many years of successfully fixing a wide range of foundation problems. Technicians should have up-to-date knowledge of current repair methods and materials. Contact the company to ask how long the business has served your community.

Reputation

Carefully reading online reviews, checking the Better Business Bureau, and getting local references helps confirm that a company consistently delivers top-notch workmanship and good customer service. Pay attention to any complaints about shoddy repairs or poor service.

Licensing and Insurance

Make sure any professional you hire has the right credentials, bonds, and coverage for liability and workers' compensation. General contractors in California must be licensed by the Contractors State License Board before working on projects valued at $500 or more. To apply for a license, an individual must have at least four years of relevant work experience in the last decade (or be represented by someone who does), must pass both a business and law and a trade exam, and must be bonded. If an individual or business has employees, workers' compensation insurance is also required. Contractors may have to meet additional requirements to do certain work with concrete.

Warranties

Look for a company that provides transferable coverage for a minimum of 10 years, or preferably lifetime guarantees, to back its foundation repairs. This demonstrates that the company stands behind its work and safeguards you if issues arise in the future.

Questions To Ask Foundation Repair Companies

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

  • What repair method do you recommend for my specific situation and why? Your provider may offer options such as carbon fiber, steel piers, and wall anchors. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • Realistically, how long will repairs take? Look for providers that provide reasonable estimates.
  • What type of warranties are provided? Reputable companies often offer warranties of at least 10 years on labor and materials.
  • Can you provide a complete written project scope and cost estimate? Getting the details in writing helps shield you from unexpected costs.
  • What financing options do you offer? Many providers offer payment plans for larger foundation projects.
  • What foundation flaws did you find during inspection that could be causing the issue? The response should have easy-to-understand explanations and solutions. If a provider offers a vague answer, it may be trying to bill you for extra work.

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

Frequently Asked Questions About Foundation Repair in San Lorenzo, CA

There are a number of signs that your foundation needs repairs. These might include:

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

On average, San Lorenzo homeowners pay roughly $3,424 for foundation repair, although the total cost will change based on several factors. The best way to estimate the cost of your specific job is to solicit quotes from a handful of 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.

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

For both leak repair and crack repair, a technician will come to your home, perform an inspection, and use various measures to fix leaks or cracks. The amount you spend can vary greatly depending on the size and cause of the issue.

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

If you're interested in waterproofing your foundation or basement, we suggest talking to a waterproofing specialist. This process might include outdoor waterproofing, indoor waterproofing, or both.

When caring for your foundation, you should make sure that it has the proper level of moisture, especially in hot weather. San Lorenzo tends to be a very dry place, so in times of little rain you may need to water your foundation. Also be sure to promptly identify and repair any leaking pipes or gutters.

If you have any concerns about your foundation, you can reach out to a structural engineer for an evaluation. This will run you a few hundred dollars, but the 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 house, make sure to have a soil report done. This can provide information about how well the soil on your property will be able to support a foundation, and can highlight potential future issues.

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 San Lorenzo regulations.

You might not want to spend money to hire someone for what appears to be a small foundation repair. However, it's always good to consult a professional. This way, you can avoid potential future issues that could be even more expensive. You may be able to repair small hairline cracks yourself, but it's always good to get an expert opinion first.

In general, home insurance doesn't cover foundation repairs, except for those done to repair damage caused by a covered weather event. We strongly suggest talking to your home insurance company before starting any foundation repairs.
