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

Reputation

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

Licensing and Insurance

Make sure any company you hire has the appropriate licenses, bonds, and coverage for liability and workers' compensation. General contractors in California need to be licensed by the Contractors State License Board in order to work on projects valued at more than $500. To obtain 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 law and business and a trade exam, and must be bonded. Individuals or businesses that have employees must also have workers' compensation insurance. Contractors may have to meet additional requirements to do certain concrete work.

Warranties

Opt for a provider offering long transferable warranties of at least 10 years, ideally lifetime guarantees, to completely back its foundation repair work. This exhibits belief in the quality and durability of the repairs and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

During the process of selecting foundation repair providers, get detailed answers to questions such as:

  • Can you provide a complete written project scope and cost estimate? Getting the details in writing helps shield you from unexpected expenses.
  • What guarantees do you offer? Reliable companies generally provide labor and materials warranties that last at least 10 years.
  • What foundation defects did you find during inspection that could be causing the issue? The response should have easy-to-understand explanations and solutions. If a provider offers an unclear answer, it may be attempting to bill you for unneeded work.
  • What exact repair method do you recommend for this specific situation and why? Your provider may consider options such as steel piers, wall anchors, and carbon fiber. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What financing options do you have? Providers often offer payment plans for larger foundation repairs.
  • How long will the repairs realistically take? Look for providers that provide reasonable estimates.

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 offers high-quality, long-lasting repairs. Promptly fixing foundation issues reduces the risk of further structural damage.

Frequently Asked Questions About Foundation Repair in Sunnyvale, CA

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

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

On average, Sunnyvale homeowners spend about $3,286 on foundation repair. The amount you'll spend on foundation repair depends on several factors. Things like the extent of the damage, the type of repair needed, and the size of your home will all factor in. The easiest way to learn how much a job might cost is to speak with a local foundation repair expert 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 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 steel or carbon fiber strips. The cost will depend on the material chosen and how many strips are required. The cost of underpinning also varies. This process, sometimes referred to as piering or leveling, involves leveling your foundation by underpinning it with concrete piers; the cost will depend on how many piers are used.

If you're interested in waterproofing your foundation or basement, we recommend finding 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 right amount of moisture, especially in hot weather. Sunnyvale tends to be a very dry place, so in times of little rain you may need to water your foundation. Additionally, make sure that you quickly identify and fix any leaking gutters or pipes.

If you have any concerns about your foundation, you can call a structural engineer for an evaluation. This will cost a few hundred dollars, but the consultation can net you a list of things to be aware of as well as additional steps to further protect your foundation. Lastly, if you're building a new house, ensure that you have a soil report done. This report provides information about how well the soil on your property can support a foundation and highlights potential future issues.

Foundation repair usually requires a permit, but getting one isn't your responsibility. Your foundation repair professional should put together all the permits and other documents required in Sunnyvale, and should be able to explain the process and/or provide the documents if asked.

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

The two categories of waterproofing are interior and exterior waterproofing. Interior waterproofing is often less expensive, and can involve solutions such as the use of sealants or the installation of sump pumps or drains. Exterior waterproofing is generally more expensive but more effective. Exterior waterproofing can involve things like external drains, landscaping changes, or physical barriers to stop water from getting into basements and crawl spaces.

It's a good idea to talk to your foundation repair professional about this before starting any project. Typically, yes, you and your family will be able to remain at home while foundation repairs are underway.
