How To Choose a Foundation Repair Company

You need a good foundation repair company to accurately evaluate issues and make appropriate repairs. Do your research and focus on these important factors when looking for the right company.

Experience

Look for a reputable local foundation provider with a proven history of successfully fixing foundations. Technicians should have expert-level understanding of current repair methods and materials. Contact the company to ask how long it’s served your community.

Reputation

Thoroughly reading online reviews, checking the Better Business Bureau, and asking for 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

Only hire providers that are properly licensed, bonded, and have both workers compensation and liability insurance. In California, general contractors need to be licensed by the Contractors State License Board before working on projects valued at more than $500. To obtain 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. There may be additional requirements for contractors to do certain concrete work.

Warranties

Pick a company that offers transferable warranties for a minimum of a decade 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 if problems come up later.

Questions To Ask Foundation Repair Companies

During the process of selecting foundation repair providers, get detailed answers to questions such as:

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

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 high-quality, long-lasting repairs. Promptly fixing foundation issues reduces the risk of further structural damage.

Frequently Asked Questions About Foundation Repair in Alamo, CA

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

On average, Alamo homeowners spend around $3,169 on foundation repair. The total cost of foundation repair will vary greatly depending on a number of factors. Things like the size of your home, the extent of the damage, and the type of repair needed will all help determine the cost. The easiest way to determine how much a job is going to cost is to talk to a local foundation repair company and schedule a free inspection and estimate.

The main 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 contractor will perform an inspection and complete any repairs necessary to remedy cracks or leaks. The price will vary based on the size and cause of the problem.

Underpinning, also called leveling or piering, is the process of leveling your foundation by underpinning it with large concrete piers. The cost will depend on how many piers are needed. The price of stabilization varies similarly. This process reinforces bowing walls with carbon fiber or steel strips, and the cost will depend on what material is used and how many strips are used.

Lastly, waterproofing is an overarching term for a number of jobs intended to stop water from getting into your foundation. This can involve exterior waterproofing, interior waterproofing, or both, and costs can vary widely. We recommend contacting a waterproofing specialist if you're planning to waterproof your foundation.

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

If you have any concerns about your foundation, you can call 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 more ideas to help you further protect your foundation. Lastly, if you're constructing a new house, be sure to have a soil report done. This report provides information about how well the soil on your property can support a foundation and highlights potential future problems.

Permits are needed for most foundation repairs, but obtaining one shouldn't be your responsibility. Your foundation repair provider should obtain the permit and all other documents required in Alamo, and should be able to provide the documents and/or explain the process before starting work.

While some foundation issues might appear small and not worth the cost to fix, when left untreated, they can lead to larger and more expensive problems later on. Foundation issues can also have underlying causes which are not clear until after a professional inspection. It's important to identify and fix these underlying issues as soon as possible. For these reasons, we recommend you don't procrastinate on foundation repairs.

Foundation repair, particularly very involved repairs like basement waterproofing, should last a long time. This is particularly true if you go with a reliable company. By solving systemic issues with your foundation, or reinforcing key areas, you lower your risk of future problems.
