How To Choose a Foundation Repair Company

Conduct research before beginning your foundation repair project in order to find the most qualified foundation repair provider. Here are the main factors to consider.

Experience

Look for a reputable local foundation provider with many years of successfully fixing all foundation types. Technicians should have up-to-date knowledge of current repair methods and materials. Contact the company to ask how long it’s served your community.

Reputation

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

Licensing and Insurance

Only hire companies that are properly licensed, bonded, and have both workers compensation and liability insurance. General contractors in California are required to be licensed by the Contractors State License Board in order to work on projects valued at more than $500. To be eligible for a license, an individual must have at least four years of relevant 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. Individuals or businesses that have employees must also have workers' compensation insurance. There may be additional requirements for contractors to do certain work with concrete.

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

When examining potential foundation repair companies, make sure to ask in-depth questions such as:

  • What repairs do you recommend for this situation, and why? Your contractor may provide 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 guarantees do you offer? Reliable companies usually provide labor and materials warranties that last at least 10 years.
  • What are some likely causes of the problem based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide unclear answers may be trying to bill you for unnecessary work.
  • How long will repairs realistically take to complete? Look for providers that provide reasonable estimates.
  • What financing options do you offer? Many providers offer payment plans for larger foundation projects.
  • Can you provide a complete written project scope and cost estimate? Getting the details in writing helps shield you from unexpected costs.

Taking time to carefully evaluate foundation repair contractors will help homeowners discover the right company for their needs. A company that can thoroughly answer these questions is likely one that offers high-quality, long-lasting repairs. Swiftly addressing foundation issues helps avoid further structural damage.

Frequently Asked Questions About Foundation Repair in Los Gatos, CA

If your foundation needs repairs, it may manifest in a number of ways. Outside, you might see a crumbling or cracking foundation or cracks in your driveway. Your ground level may have uneven or cracked floors. You might notice doors or windows that are sticking in their frames, or that the frames are skewed. You might also notice cracking, bowing, or buckling walls.

On average, Los Gatos homeowners spend around $3,287 on foundation repair. The total cost of foundation repair will vary greatly depending on several factors. Things like the extent of the damage, the size of your home, and the type of repair needed will all play a part. The easiest way to find out how much a job could cost is to reach out to 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, perform an inspection, and use various measures to remedy leaks or cracks. The cost of these procedures can vary greatly depending on the size and root cause of the problem.

Stabilization reinforces bowing walls by inserting steel or carbon fiber strips. The cost will depend on the material chosen and the number of strips required. 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 suggest finding a waterproofing specialist. This process might include outdoor waterproofing, indoor waterproofing, or both.

When caring for your foundation, you should make sure that it has the proper level of moisture, especially in hot weather. Los Gatos tends to be a very dry place, so in times of little rain you may need to water your foundation. Also be sure to 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 run you a few hundred dollars, but the engineer's consultation can provide you with a list of things to be aware of as well as steps you can take to further protect your foundation. Lastly, if you're constructing a new house, ensure that you have a soil report done. This report provides information regarding how well the soil on your property will be able to support a foundation and highlights potential future issues.

Permits are needed for most foundation repairs, but applying for one shouldn't be your responsibility. Your foundation repair professional should put together the permit and all other documents required in Los Gatos, and should be able to provide the documents and/or explain the process if asked.

Some signs that you're in need of foundation waterproofing include white powder or spots on your walls, discoloration or odors, hairline cracks, basement flooding, uneven floors, or signs of mildew, fungus, or mold. Your contractor can tell you whether you need interior or exterior waterproofing.

Interior waterproofing can involve the use of sealants or the installation of sump pumps and drains and generally is less expensive than exterior waterproofing. Exterior waterproofing can involve things like applying physical barriers to basements and crawl spaces, changing your landscaping, or installing exterior drains.

We advise against putting off a foundation repair project. A seemingly small issue may have an underlying cause that could lead to numerous future problems, and it's better to get ahead of the issue as soon as possible. A small and moderately costly problem now could turn into a large and expensive one in the future if left untreated.
