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 conduct research beforehand, focusing on the factors listed here.

Experience

Find a local foundation repair provider with deep experience fixing all types of foundations. It should have specialized knowledge of the latest repair methods and materials. Ask how long a provider has served your area.

Reputation

Spend time researching online reviews, browsing the Better Business Bureau, and requesting local references. This will help verify that a provider consistently delivers quality work and professionalism. Take note of any complaints mentioning poor service or faulty repairs.

Licensing and Insurance

It's important to select a provider that has the correct licenses, bonding, and insurance for liability and workers' compensation. General contractors in California need to be licensed by the Contractors State License Board before working on projects valued over $500. To apply for a license, an individual needs to have at least four years of related work experience in the last ten years (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 concrete work.

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 that they stand behind the quality of their repairs and offers protection if future issues arise.

Questions To Ask Foundation Repair Companies

To compare foundation repair companies, you should ask detailed questions such as:

  • What warranties do you offer? Reliable companies generally provide labor and materials warranties that last at least 10 years.
  • What financing options do you have? Many providers offer payment plans for larger foundation projects.
  • What repair method would you recommend for this specific situation and why? Your provider may consider 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 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 attempting to bill you for unneeded work.
  • How long will the repairs realistically take? Look for companies that provide reasonable estimates.
  • Can you provide a project scope and cost estimate in writing? Be sure to get quotes in writing to shield yourself from unexpected costs.

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

Frequently Asked Questions About Foundation Repair in Concord, CA

There are a number of signs that your foundation is in need of repair. These can include:

  • Visible crumbling or cracks in your foundation
  • Uneven ground-level floors
  • Bowing, buckling, or cracked walls
  • Door frames or window frames that are skewed or tight
  • Cracks in your basement floor
  • Cracks in your driveway

On average, Concord homeowners spend about $3,169 on foundation repair. The total cost of foundation repair will vary greatly depending on several factors. Things like the size of your home, the type of repair needed, and the extent of the damage will all factor in. The best way to learn how much a job may cost is to talk to a local foundation repair expert and schedule a free inspection and estimate.

The primary 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 the process of leveling 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 reinforces bowing walls with steel or carbon fiber strips, and the total cost will depend on the material and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs intended to prevent water from getting into your foundation. This can involve exterior waterproofing, interior waterproofing, or both, and costs can vary greatly. We recommend contacting a waterproofing specialist if you're planning to waterproof your foundation.

When constructing a new house, make sure that a soil report is completed. A soil report will contain information about how well the soil on a given piece of land can support a foundation, and can give you a heads-up about any potential future problems. If you have concerns about an existing home, a few hundred dollars will cover an inspection and report by a structural engineer. They can point you to any issues that need attention, and give you advice on avoiding future problems.

It's also important that the moisture around your foundation is appropriate, particularly when the weather gets hot. The weather in Concord tends to be very dry, which means that at times you may need to water your soil and foundation. Also, be on the lookout for leaky gutters or pipes and repair them quickly.

Your foundation repair expert should be the one obtaining the permits. You can ask the company to provide a detailed explanation of its process and to see the permits and paperwork it has acquired to make sure everything is properly authorized per Concord regulations.

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

The two categories of waterproofing are interior and exterior waterproofing. Interior waterproofing is generally less expensive, and involves solutions such as the use of sealants or the installation of drains or sump pumps. Exterior waterproofing is 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.

While some foundation issues may appear small and not worth the cost to repair, when left untreated, they can cause much larger and more expensive problems later on. Foundation problems may have underlying causes which are not readily apparent until after a professional inspection. It's important to fix these underlying issues as soon as possible. For these reasons, we advise against procrastinating on foundation repairs.
