How To Choose a Foundation Repair Company

Hiring a qualified foundation repair business 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

Look for a local foundation repair provider with deep experience fixing all types of foundations. It should have expertise in the latest repair techniques 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 provider consistently delivers top-notch workmanship and good customer service. Pay attention to any complaints about poor service or faulty repairs.

Licensing and Insurance

Choose a company that has the proper licenses, bonds, and coverage plans for liability and workers' compensation. General contractors in California must be licensed by the Contractors State License Board in order to work 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 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

Choose a provider that offers transferable warranties of at least a decade, ideally up to lifetime guarantees, to fully back their foundation repairs. This demonstrates confidence in the quality of their work and offers protection if future issues arise.

Questions To Ask Foundation Repair Companies

As you evaluate potential foundation repair companies, make sure to ask in-depth questions such as:

  • Realistically, how long will the repairs take to complete? Look for providers that provide reasonable estimates.
  • What financing options do you offer? Providers often offer payment plans for larger foundation repairs.
  • Can you provide a cost estimate and project scope in writing? Make sure to get quotes in writing to shield yourself from unexpected expenses.
  • What repairs do you recommend for this situation, and why? Your contractor may provide 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.
  • What guarantees do you provide? Reputable providers generally provide labor and materials warranties of at least 10 years.
  • What do you see as the likely cause of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide vague answers may be attempting to bill you for extra work.

Thoroughly reviewing foundation repair companies helps homeowners identify the best fit for their needs. A company that can answer the above questions likely completes long-lasting, quality repairs. Repairing foundation problems swiftly reduces the risk of future structural damage.

Frequently Asked Questions About Foundation Repair in Hercules, CA

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

On average, Hercules homeowners pay about $3,169 for foundation repair, although the cost will change based on several factors. The fastest way to get an estimate for the cost of your specific project is to request quotes from one or more local foundation repair companies. The amount you pay for a job will be influenced by things like the size of your house and type of repair(s) needed.

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

Leak repair and crack repair involve a technician coming to your home, completing an inspection, and using various measures to fix leaks or cracks. The amount you spend will vary greatly depending on the size and root cause of the issue.

Stabilization reinforces 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 will depend on how many piers are needed.

If you're looking to waterproof your foundation or basement, we suggest speaking with a waterproofing specialist. This process can include outdoor waterproofing, indoor waterproofing, or both.

When caring for your foundation, you should make sure it gets the proper level of moisture, especially in hot weather. Hercules 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 reach out to a structural engineer for an evaluation. This will cost a few hundred dollars, but the engineer's consultation can provide you with a list of things to look out for as well as steps you can take to further protect your foundation. Lastly, if you're constructing a new home, be sure that you have a soil report done. This can provide information about 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 applying for one shouldn't be your responsibility. Your foundation repair provider should obtain the permit and all other documents required in Hercules, and should be able to explain the process and/or provide the documents before starting work.

If your foundation needs waterproofing, you'll start to notice signs like discoloration or odors, uneven floors, hairline cracks, white powder or spots on your walls, basement flooding, or signs of mildew, fungus, or mold.

The two categories of waterproofing are interior and exterior waterproofing. Interior waterproofing tends to be less expensive, and involves measures like the use of sealants or the installation of sump pumps or drains. Exterior waterproofing tends to be more expensive but more effective. This process can involve things like external drains, landscaping changes, or physical barriers to stop water from getting into basements and crawl spaces.

We caution against putting off a foundation repair project. Minor issues may have an underlying cause that could lead to numerous future problems, and it's best to treat the root of the issue as fast as possible. A small and moderately costly problem now could become a large and very expensive one in the future if left untreated.
