How To Choose a Foundation Repair Company

You need a good foundation repair company to properly assess issues and make appropriate repairs. Do thorough research and focus on these factors when selecting the right company.

Experience

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

Reputation

Reading through online reviews, checking the Better Business Bureau, and requesting local references helps you confirm that a provider consistently delivers good workmanship and a positive customer service experience. Pay attention if you see multiple complaints about shoddy repairs or poor service.

Licensing and Insurance

It's important to select a company that has the right credentials, bonding, and coverage for liability and workers' compensation. General contractors in California are required to be licensed by the Contractors State License Board in order to work on projects valued over $500. To obtain a license, an individual must 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. Individuals or businesses that have employees must also have workers' compensation insurance. There may be additional requirements for contractors to do certain concrete work.

Warranties

Pick a provider that offers long transferable warranties for a minimum of 10 years and, if possible, lifetime guarantees to fully back its services. This displays faith that their repairs will be high-quality and long-lasting and provides protection should problems come up later.

Questions To Ask Foundation Repair Companies

When examining potential foundation repair companies, make sure to ask specific questions such as:

  • What repair method do you recommend for this specific situation and why? Your provider may offer options such as wall anchors, carbon fiber, and steel piers. Asking allows you to compare suggested solutions between companies.
  • 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 unclear answers may be attempting to bill you for unneeded work.
  • What options do you offer for financing? Many providers offer payment plans for larger foundation projects.
  • Can you provide a cost estimate and project scope in writing? Be sure to get quotes in writing to shield yourself from unexpected costs.
  • How long will the repairs realistically take? Look for providers that provide reasonable estimates.
  • What warranties do you offer? Reputable providers typically provide labor and materials warranties that last at least 10 years.

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. Addressing foundation problems swiftly decreases the risk of future structural damage.

Frequently Asked Questions About Foundation Repair in San Jose, CA

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

On average, San Jose homeowners pay roughly $3,287 for foundation repair, although the total cost will depend on several factors. The fastest way to estimate the cost of your specific project is to ask for quotes from a few local foundation repair companies. The total price will be affected by things like the type of the repair(s) and the size of your house.

The primary types of foundation repair include crack repair, leak repair, underpinning, stabilization, and waterproofing.

Crack repair and leak repair are what they sound like: your foundation contractor will perform an inspection and take necessary measures to remedy cracks or leaks. The price will vary depending on the size and cause of the problem.

Underpinning, also called piering or leveling, is the process of leveling your foundation by underpinning it with large concrete piers. The cost will depend on how many piers are needed. The price of stabilization varies similarly. This process involves fixing bowing walls by reinforcing them with carbon fiber or steel strips, and the cost will depend on the material and how many strips are used.

Lastly, waterproofing is an overarching term for a category of repairs that help stop water from getting into your foundation. This can include interior waterproofing, exterior waterproofing, or both, and costs can vary widely. We recommend contacting a waterproofing specialist if you're interested in waterproofing your foundation.

When building 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 provide you with a heads-up about potential future issues. If your concerns are about an existing house, for a few hundred dollars, you can get an inspection and report by a structural engineer. They can alert you to any current problems that could use some attention, and give you advice on avoiding future problems.

You also want to make sure that the moisture around your foundation is at an appropriate level, particularly when the weather gets hot. The weather in San Jose tends to be very dry, which means that at times you may need to water your soil and foundation. You should also stay vigilant for leaky pipes or gutters and repair them quickly.

Your foundation repair provider should be the one to get the permits. You can request that the company provide a detailed explanation of its process and to see the permits and paperwork it has assembled to confirm everything is properly authorized per San Jose regulations.

Typically, your home insurance won't cover foundation repairs, except for those done to repair damage resulting from a covered weather event. It's a smart idea to talk to your home insurance company before starting any foundation repairs.

Foundation repairs carried out by a trustworthy company should last a long time. Large repairs, such as basement waterproofing, can be involved and expensive, but they go a long way toward reducing your risk of future issues.
