How To Choose a Foundation Repair Company

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

Experience

Choose a well-established local company with a long track record of experience successfully handling all types of foundation repairs. These providers have specialized expertise with the latest methods and materials. Ask how long a company has served homes in your area.

Reputation

Looking through online reviews, checking the Better Business Bureau, and requesting local references helps verify that a company regularly provides good workmanship and good service. Pay attention if you see numerous complaints about faulty repairs or poor service.

Licensing and Insurance

Only hire companies that are properly licensed, bonded, and have both liability and workers compensation insurance. In California, general contractors must be licensed by the Contractors State License Board before working on projects valued at more than $500. To be eligible for a license, an individual needs to have at least four years of relevant work experience in the last decade (or be represented by someone who does), must pass both a law and business 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 come up in the future.

Questions To Ask Foundation Repair Companies

While researching options for foundation repair providers, get detailed answers to questions such as:

  • What type of warranties do you offer? Trustworthy providers will offer warranties of minimum 10 years on labor and materials.
  • Can you provide a cost estimate and project scope in writing? Make sure to get quotes in writing to shield yourself from unexpected expenses.
  • Realistically, how long will repairs take? Look for providers that provide reasonable estimates.
  • What options do you have for financing? Providers often offer payment plans for larger foundation repairs.
  • What repairs do you recommend for this situation, and why? Your contractor may offer options such as wall anchors, steel piers, and carbon fiber. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What foundation flaws did you identify 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.

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 offers long-lasting, durable repairs. Promptly fixing foundation problems helps prevent further structural damage.

Frequently Asked Questions About Foundation Repair in Napa, CA

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

  • Visible crumbling or cracking of 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, Napa homeowners pay roughly $2,882 for foundation repair, although the cost will depend on several factors. The fastest way to get an estimate for the cost of your specific job is to solicit quotes from one or more local foundation repair companies. Your total cost will be determined by things like the size of your house and type of repair(s) needed.

The primary types of foundation repair are crack repair, leak repair, underpinning, stabilization, and waterproofing.

Crack repair and leak repair are what they sound like: your foundation repair expert will perform an inspection and complete any repairs necessary to remedy cracks or leaks. The price will vary depending on the size and cause of the problem.

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 varies similarly. This process fixes bowing walls by reinforcing them with steel or carbon fiber strips. The total cost will depend on what material is used and how many strips are used.

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

One way to protect your foundation is to make sure that it gets the proper level of moisture, especially in hot weather. Avoid letting the soil around your Napa house become too wet or too dry – make changes to your gutter system to route water away, or water your foundation if it starts to get too dry. Additionally, be sure to quickly 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 cost a few hundred dollars, but the engineer's consultation can net you a list of things to be aware of as well as additional steps to further protect your foundation. Finally, if you're building a new home, be sure that you have a soil report done. This can provide information regarding how well the soil on your property can support a foundation, and can highlight any potential future issues.

A permit is normally required for foundation repair, but obtaining one won't be your responsibility. Your foundation repair provider should get the permit and all other documents required in Napa, and should be able to provide the documents and/or explain the process before starting work.

You may be able to take care of small hairline cracks yourself, but in most cases, you should consult a professional before you start any sort of foundation work. While you may not want to pay someone for a task you feel you can handle yourself, mistakes made during foundation repair can be even more costly in the future.

Foundation repairs can sometimes, foundation repairs can be considered capital improvements if they fit the criteria of an improvement that will add to your house's overall value, prolong its life, or adapt it to new uses. In some cases, making capital improvements helps you qualify for tax breaks. (Talk to your California tax professional to learn more.) Tax breaks aside, foundation repairs will, in most cases, positively affect your home's value.
