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 conduct research beforehand, focusing on the factors listed here.

Experience

Find 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. Asking allows you to compare suggested solutions between companies.
  • What options do you have for financing? Providers often offer payment plans for larger foundation repairs.

Thoroughly assessing foundation repair companies helps homeowners select the ideal match for their needs. A provider that can answer the questions above is likely one that delivers long-lasting, durable repairs. Promptly fixing foundation problems helps avoid further structural damage.

Frequently Asked Questions About Foundation Repair in Castro Valley, CA

There are a variety of signs that your foundation needs repairs. These can include:

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

On average, Castro Valley homeowners pay about $3,424 for foundation repair, although the cost will change based on several factors. The best way to estimate the cost of a specific project is to ask for quotes from one or more local foundation repair companies. The amount you pay for a job will be determined by things like the size of your house and type of repair(s) needed.

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 repair expert will perform an inspection and complete any repairs necessary to remedy cracks or leaks. Costs will depend on the size and cause of the issue.

Underpinning, also called leveling or piering, 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. The total cost will depend on the material chosen and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs that help 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 think your foundation needs waterproofing.

When building a new home, have a soil report completed. This report contains information about how well the soil on a given piece of land can support a foundation, and can give you a heads-up about potential future problems. If your concerns are about an existing home, a few hundred dollars will cover an inspection and report by a structural engineer. They can alert you to any things that could use some attention, and advise you on avoiding future problems.

You also want to make sure that the moisture around your foundation is appropriate, particularly when the weather gets hot. The weather in Castro Valley 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 quickly.

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 not want to spend money to hire someone for a seemingly small foundation repair. However, it's always good to consult a professional. This helps you avoid more expensive issues down the road. It may be possible to fix small hairline cracks yourself, but it's always a smart idea to get an expert opinion first.

The amount of time a foundation repair takes varies greatly based on the type of repair needed and the size of your house. Most repairs will take anywhere from one to several weeks. Consult your Castro Valley foundation repair expert for the specific timeline for your project.
