How To Choose a Foundation Repair Company

Working with a qualified foundation repair company is important for accurately evaluating the damage and making the right repairs. We suggest focusing on these key factors.

Experience

Look for a reputable local foundation provider with many years of successfully fixing foundations. Technicians should have extensive experience with current repair methods and materials. Contact the company to ask how long the business has served your community.

Reputation

Researching online reviews, checking the Better Business Bureau, and requesting local references helps you confirm that the company consistently delivers good workmanship and a great customer experience. Pay attention if you see multiple complaints about poor service or faulty repairs.

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 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 work with concrete.

Warranties

Opt for a provider offering transferable coverage for 10+ years, ideally lifetime guarantees, to completely back its repair work. This exhibits confidence that the repairs will be effective and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

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

  • What options do you offer for financing? Providers often offer payment plans for larger foundation repairs.
  • Can you provide a cost estimate and project scope in writing? Be sure to get quotes in writing to shield yourself from unexpected expenses.
  • What foundation defects 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 an unclear answer, it may be trying to bill you for unnecessary work.
  • What repairs do you recommend for my situation, and why? Your contractor may consider options such as carbon fiber, wall anchors, and steel piers. Asking allows you to compare suggested solutions between companies.
  • What warranties do you offer? Reputable providers generally provide labor and materials warranties that last at least 10 years.
  • How long will the repairs realistically take? Look for companies that provide reasonable estimates.

Thoroughly reviewing foundation repair companies helps homeowners locate the best fit for their needs. A company that can answer the above questions likely delivers long-lasting, quality repairs. Repairing foundation problems right away lowers the risk of future structural damage.

Frequently Asked Questions About Foundation Repair in Moraga, CA

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

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

On average, Moraga homeowners spend around $3,169 on foundation repair. The cost of foundation repair is based on several factors. Things like the type of repair needed, the size of your home, and the extent of the damage will all play a part. The best way to learn how much a job might cost is to contact a local foundation repair company and schedule a free inspection and estimate.

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

For both leak repair and crack repair, a technician will come to your home, complete an inspection, and use various repair techniques to remedy leaks or cracks. The amount you spend can vary greatly depending on the size and root cause of the problem.

Stabilization is the process of fixing bowing walls by inserting steel or carbon fiber strips. The cost will depend on the material used and how many strips are needed. The cost of underpinning also varies. This process, also called piering or leveling, involves underpinning your foundation with concrete piers to level it; the cost is based on how many piers are used.

If you're looking to waterproof your foundation or basement, we recommend looking for a waterproofing specialist. This process may include indoor waterproofing, outdoor waterproofing, or both.

If you're constructing a new home, make sure that a soil report is completed. This report contains information regarding how well your soil 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. The engineer can point you to any things that could use some 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 Moraga 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, so you can get them repaired promptly.

Your foundation repair professional should be the one to get the permits. You can ask the company to provide a detailed explanation of the steps in its process and to see the paperwork and permits it has assembled to ensure everything is properly authorized per Moraga regulations.

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

You can opt for interior or exterior waterproofing. Interior waterproofing is generally less expensive, and involves solutions like the use of sealants or the installation of sump pumps or drains. Exterior waterproofing tends to be more expensive but more effective. Exterior waterproofing can involve things like landscaping changes, external drains, or physical barriers to keep water out of basements and crawl spaces.

We highly recommend contacting your home insurance provider before beginning any foundation repairs to learn about what might be covered. Typically, foundation repairs aren't covered by your home insurance unless they're to repair damage that was caused by a covered weather event.
