How To Choose a Foundation Repair Company

Hiring a qualified foundation repair business ensures you have someone who will inspect the damage thoroughly and make appropriate fixes. It's important to conduct research beforehand, focusing on the factors listed here.

Experience

We recommend choosing a local foundation repair provider with a proven reputation for fixing various kinds of foundation problems. These companies should have expertise in the latest techniques and materials. Ask providers how long they've served your area.

Reputation

Spend time researching online reviews, browsing the Better Business Bureau, and requesting local references. This will help confirm that a provider consistently delivers good workmanship and professionalism. Take note of complaints mentioning faulty repairs or poor service.

Licensing and Insurance

Make sure any professional you hire has the appropriate licenses, bonds, and insurance for liability and workers' compensation. In California, general contractors 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 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. There may be additional requirements for contractors to do certain work with concrete.

Warranties

Choose a company that offers long transferable warranties of at least 10 years, ideally up to lifetime guarantees, to back their foundation repairs. This demonstrates that they stand behind the quality of their repairs and offers protection if future issues arise.

Questions To Ask Foundation Repair Companies

While researching options for foundation repair providers, get detailed answers to questions such as:

  • What warranties do you offer? Reputable providers typically provide labor and materials warranties that last at least 10 years.
  • What financing options do you have? Many providers offer payment plans for larger foundation projects.
  • What repairs would you recommend for this situation, and why? Your contractor may offer options such as carbon fiber, wall anchors, and steel piers. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What are some likely causes 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 unnecessary work.
  • Can you provide a complete written cost estimate and project scope? Asking for a quote in writing helps shield you from unexpected expenses.
  • Realistically, how long will repairs take to complete? Look for providers that provide reasonable estimates.

Taking time to vet foundation repair companies will help you locate the right one for you. Providers that can thoroughly answer these questions will likely provide long-lasting, high-quality repairs. Promptly addressing foundation issues helps prevent future structural damage.

Frequently Asked Questions About Foundation Repair in Alum Rock, CA

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

On average, Alum Rock homeowners pay roughly $3,287 for foundation repair, although the actual cost will depend on several factors. The best way to estimate the cost of a specific project is to solicit quotes from a handful of local foundation repair companies. Your total cost will be influenced by things like the type of the repair(s) and the size of your house.

Types of foundation repair include leak repair, crack repair, stabilization, underpinning, and waterproofing.

Leak repair and crack repair involve a technician coming to your home, completing an inspection, and using various repair techniques to fix leaks or cracks. The cost of these procedures will vary greatly depending on the size and cause of the problem.

Stabilization is the process of fixing 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 piering or leveling, involves underpinning your foundation with concrete piers to level it; the cost will depend on how many piers are needed.

If you're interested in waterproofing your foundation or basement, we recommend talking to a waterproofing specialist. This process may include outdoor waterproofing, indoor waterproofing, or both.

If you're constructing a new house, make sure that a soil report is completed. A soil report will contain information about how well the soil on a given piece of land can support a foundation, and can offer you a heads-up about any potential future problems. If you have concerns about an existing house, for a few hundred dollars, you can get an inspection and report by a structural engineer. They can point you to any current problems that need attention, and give you advice on how to avoid future problems.

It's also important that the moisture around your foundation is at an appropriate level, particularly when the weather gets hot. The weather in Alum Rock 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 professional should acquire the needed permits. You can request that the company provide a detailed explanation of the steps in its process and to see the permits and paperwork it has acquired to confirm everything is properly authorized per Alum Rock regulations.

Sometimes, foundation repairs can be considered capital improvements if they meet the criteria of an improvement that adds to a home's overall value, prolongs its life, or adapts it to new uses. In some cases, making capital improvements lets you qualify for tax breaks. (Contact your California tax professional to learn more.) Even without these tax breaks, foundation repairs will, in most cases, positively affect your home's value.

In most cases, your home insurance won't cover foundation repairs, unless the repair is to fix damage caused by a covered weather event. It's a good idea to talk to your home insurance company before you start any foundation repairs.
