How To Choose a Foundation Repair Company

Research thoroughly before starting your foundation repair project in order to find the most qualified foundation repair provider. Here are the main factors you should consider.

Experience

Pick a local foundation repair company with extensive 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

Researching online reviews, checking the Better Business Bureau, and asking for local references helps you verify that the company consistently delivers quality work and a great customer experience. Pay attention if you see multiple complaints about poor service or faulty repairs.

Licensing and Insurance

It's important to select a company that has valid credentials, bonding, and insurance for liability and workers' compensation. General contractors in California must be licensed by the Contractors State License Board in order to work on projects valued over $500. To be eligible for a license, an individual must have at least four years of related work experience in the last decade (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 foundation services. 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 providers, you should ask detailed questions such as:

  • What warranties do you provide? Reliable companies usually provide labor and materials warranties that last at least 10 years.
  • Realistically, how long will the repairs take? Look for providers that provide reasonable estimates.
  • What repairs would you recommend for this situation, and why? Your contractor may offer options such as carbon fiber, wall anchors, and steel piers. Asking allows you to compare suggested solutions between companies.
  • What options do you offer for financing? Many providers offer payment plans for larger foundation projects.
  • 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.
  • Can you provide a complete written cost estimate and project scope? Getting quotes in writing helps shield you from unexpected expenses.

Carefully reviewing foundation repair companies will help you locate the right one for you. Providers that can thoroughly answer these questions will likely provide durable, high-quality repairs. Swiftly fixing foundation issues helps avoid future structural damage.

Frequently Asked Questions About Foundation Repair in San Mateo, CA

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

On average, San Mateo homeowners pay about $2,882 for foundation repair, although the cost will vary widely depending on several factors. The fastest way to get an estimate for the cost of your specific job is to solicit quotes from one or more local foundation repair companies. Your total cost will be determined by things like the size of your house and type of repair(s) needed.

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 repair techniques to remedy leaks or cracks. The cost of these procedures can vary greatly depending on the size and root cause of the problem.

Stabilization involves reinforcing bowing walls by inserting steel or carbon fiber strips. The cost will depend on the material used and the number of strips required. The cost of underpinning also varies. This process, sometimes referred to as leveling or piering, involves leveling your foundation by underpinning it with concrete piers; the cost depends on how many piers are needed.

If you're looking to waterproof your foundation or basement, we suggest speaking with a waterproofing specialist. This process might include outdoor waterproofing, indoor waterproofing, or both.

When 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 offer you a heads-up about potential future issues. If your concerns are about an existing home, a few hundred dollars will cover an inspection and report by a structural engineer. They can point you to any current problems that need attention, and advise you on how to avoid future problems.

You also want to make sure that the moisture around your foundation is appropriate. The weather in San Mateo 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 quickly.

Foundation repair usually requires a permit, but getting one shouldn't be your responsibility. Your foundation repair professional should obtain all the permits and other documents required in San Mateo, and should be able to provide the documents and/or explain the process before starting work.

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

Your options include interior and exterior waterproofing. Interior waterproofing typically is less expensive, and can involve solutions like the use of sealants or the installation of sump pumps or drains. 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.

In general, foundation repairs will have a positive effect on the value of your home. In some cases, you may be able to consider foundation repair a capital improvement, which might allow you to qualify for tax breaks. A capital improvement is generally defined as one that will add to a home's overall market value, prolong its life, or adapt it to new uses. Talk to your California tax professional for the most accurate information.
