How To Choose a Foundation Repair Company

Hiring a qualified foundation repair provider 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 company with extensive experience fixing all kinds of foundation problems. It should have specialized knowledge of the latest repair methods and materials. Ask how long a provider has served your area.

Reputation

Carefully reading online reviews, checking the Better Business Bureau, and asking for local references helps confirm that a company consistently delivers high-quality work and great service. Pay attention to any complaints about shoddy repairs or poor service.

Licensing and Insurance

Choose a company that has the proper licenses, bonds, and coverage plans for liability and workers' compensation. In California, general contractors must be licensed by the Contractors State License Board in order to work on projects valued at more than $500. To be eligible for 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 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 provider that offers lengthy transferable warranties for a minimum of a decade, or preferably lifetime guarantees, to back its foundation repairs. This demonstrates faith that its services are top-quality and safeguards you if issues arise in the future.

Questions To Ask Foundation Repair Companies

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

  • How long will the repairs realistically take to complete? Look for providers that provide reasonable estimates.
  • What warranties do you offer? Reliable companies generally provide labor and materials warranties of at least 10 years.
  • What do you see as the likely cause of the problem based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide unclear answers may be trying to bill you for unnecessary work.
  • Can you provide a complete written cost estimate and project scope? Getting quotes in writing helps protect you from unexpected costs.
  • 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.
  • What options do you offer for financing? Providers often offer payment plans for larger foundation repairs.

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 provides high-quality, long-lasting repairs. Swiftly addressing foundation issues reduces the risk of further structural damage.

Frequently Asked Questions About Foundation Repair in Castro Valley, CA

If your foundation is in need of repair, it may manifest in a number of ways. Outside your home, you might notice a crumbling or cracking foundation or cracks in your driveway. Your ground level might have uneven or cracked floors. You might notice windows and doors that are sticking in their frames, or frames that are skewed. You may also notice buckling, cracking, or bowing walls.

On average, Castro Valley homeowners pay roughly $3,425 for foundation repair, although the total cost will depend on several factors. The fastest way to estimate the cost of your specific job is to solicit quotes from a few local foundation repair companies. The amount you pay for a job 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, complete an inspection, and use various repair techniques to remedy leaks or cracks. The amount you spend will vary greatly depending on the size and cause of the issue.

Stabilization is the process of fixing bowing walls by inserting carbon fiber or steel strips. The cost will depend on the material chosen and the number of strips required. 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 is 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 can include outdoor waterproofing, indoor waterproofing, or both.

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

If you have any concerns about your foundation, you can contact a structural engineer for an evaluation. This will run you a few hundred dollars, but the consultation can provide you with a list of things to be aware of as well as steps you can take to further protect your foundation. Finally, if you're constructing a new house, make sure that you have a soil report done. This report provides information about how well the soil on your property can support a foundation and highlights any potential future issues.

Your foundation repair expert should acquire the needed permits. You can ask the company to provide a detailed explanation of the steps in its process and to see the permits and paperwork it has assembled to make sure everything is properly authorized per Castro Valley regulations.

You may be able to take care of small hairline cracks yourself, but in most cases, it's a good idea to consult a professional before you begin any sort of foundation maintenance. While you may not want to pay someone for work you feel like you can handle yourself, foundation repair mistakes can cost you much more in the future.

Generally, foundation repair takes from one to several weeks. This range is large because the time taken will vary greatly based on factors like the type of repair required and the size of your house. You should talk to your Castro Valley foundation repair professional for a more accurate timeline for your specific project.
