How To Choose a Foundation Repair Company

Working with a qualified foundation repair business is important for accurately evaluating the damage and completing repairs correctly. We suggest focusing on these key factors.

Experience

Look for a reputable local foundation provider with a proven history 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 verify that a provider consistently delivers good workmanship 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. In California, general contractors are required to be licensed by the Contractors State License Board before working on projects valued at more than $500. To obtain 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. 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

Opt for a provider offering transferable coverage for 10+ years, ideally lifetime guarantees, to completely back its foundation repair work. This exhibits confidence that the repairs will be effective and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

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

  • What repair method do you recommend for my specific situation and why? Your provider may offer options such as steel piers, carbon fiber, and wall anchors. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • Realistically, how long will the repairs take? Look for providers that provide reasonable estimates.
  • Can you provide a project scope and cost estimate in writing? Make sure to get quotes in writing to protect yourself from unexpected expenses.
  • What type of guarantees do you offer? Trustworthy providers often offer warranties of at least 10 years on materials and labor.
  • 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 trying to bill you for extra work.
  • What options do you offer for financing? Providers often offer payment plans for larger foundation repairs.

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 prevent further structural damage.

Frequently Asked Questions About Foundation Repair in Altadena, 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 a cracked 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 buckling, cracking, or bowing walls.

On average, Altadena homeowners pay about $2,705 for foundation repair, although the actual cost will vary depending on several factors. The easiest way to get an estimate for the cost of your specific job is to get quotes from a handful of local foundation repair companies. Your total cost will be affected 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, complete an inspection, and use various repair techniques to remedy leaks or cracks. The amount you spend will vary greatly depending on the size and cause of the issue.

Stabilization involves reinforcing bowing walls by inserting steel or carbon fiber strips. The amount you spend will depend on the material used and the number of strips required. The cost of underpinning also varies. This process, also called 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 recommend looking for a waterproofing specialist. This process can include outdoor waterproofing, indoor waterproofing, or both.

One way to protect your foundation is to make sure that it gets the right amount of moisture, especially in hot weather. Altadena tends to be a very dry place, so in times of little rain you may need to water your foundation. Also be sure to promptly identify and fix any leaking pipes or gutters.

If you have any concerns about your foundation, you can reach out to a structural engineer for an evaluation. This will cost a few hundred dollars, but the engineer's consultation can provide you with a list of things to be aware of as well as more ideas to help you further protect your foundation. Finally, if you're constructing a new home, be sure that you have a soil report done. This can provide information regarding how well the soil on your property can support a foundation, and can highlight any potential future issues.

Your foundation repair professional 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 acquired to verify that everything is properly authorized per Altadena regulations.

You may be able to handle small hairline cracks on your own, but in general, you should at least consult a professional before you start any foundation work. While you may not want to pay someone for a task you feel like you can handle yourself, mistakes made during foundation repair can cost you much more in the future.

Foundation repairs can sometimes, foundation repairs can be considered capital improvements if they meet the criteria of an improvement that adds to your house's overall market value, prolongs its life, or adapts it to new uses. In some cases, making capital improvements allows you to qualify for tax breaks. (Talk to your California tax professional to learn more.) Even if you don't qualify for tax breaks, foundation repairs will, in most cases, positively affect your home's value.
