How To Choose a Foundation Repair Company

Working with a qualified foundation repair business is important for accurately evaluating the damage and making the right repairs. We recommend focusing on these main factors.

Experience

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

Reputation

Thoroughly reading online reviews, checking the Better Business Bureau, and asking for local references helps verify that a company consistently delivers high-quality work and good customer service. Pay attention to any complaints about shoddy repairs or poor service.

Licensing and Insurance

It's important to select a company that has the right licenses, 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 at more than $500. To obtain 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. There may be additional requirements for contractors to do certain concrete work.

Warranties

Opt for a provider offering transferable coverage for 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 comparing potential foundation repair companies, be sure to ask detailed questions such as:

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

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

Frequently Asked Questions About Foundation Repair in Hillsborough, CA

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

On average, Hillsborough homeowners spend about $2,883 on foundation repair. The amount you'll spend on foundation repair is based on a number of factors. Things like the size of your home, the type of repair needed, and the extent of the damage will all help determine the cost. The fastest way to learn how much a job is going to cost is to speak with a local foundation repair expert and schedule a free inspection and estimate.

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

Crack repair and leak repair are what they sound like: your foundation repair expert will perform an inspection and complete any repairs necessary to remedy cracks or leaks. The price will depend 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 price will be based on how many piers are needed. The price of stabilization is also variable. This process fixes bowing walls by reinforcing them with carbon fiber or steel strips, and the total cost will depend on what material is used and how many strips are used.

Lastly, waterproofing is an overarching term for a number of jobs that help prevent water from getting into your foundation. This can involve exterior waterproofing, interior waterproofing, or both, and the price can vary widely. We recommend contacting a waterproofing specialist if you're interested in waterproofing your foundation.

When constructing a new home, make sure that a soil report is completed. This report contains information about how well the soil on a given piece of land can support a foundation, and can offer you a heads-up about potential future issues. If you have concerns about an existing home, a few hundred dollars will cover an inspection and report by a structural engineer. They can alert you to any issues that need attention, and give you advice on avoiding future problems.

Also ensure that the moisture around your foundation is appropriate. The weather in Hillsborough 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 pipes or gutters, so you can get them repaired promptly.

Your foundation repair provider should be the one obtaining the permits. You can request that the company 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 Hillsborough regulations.

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

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

Foundation repairs completed by a reliable company should last a long time. Some more extensive repairs, such as basement waterproofing, can be very involved and expensive, but they are very helpful in lowering the risk of future issues.
