How To Choose a Foundation Repair Company

Research thoroughly before beginning your foundation repair project in order to find the most qualified foundation repair company. Here are the main factors we recommend considering.

Experience

Look for a reputable local foundation company with significant experience in successfully fixing a wide range of foundation problems. Technicians should have up-to-date knowledge of current repair methods and materials. Contact the company to ask how long the business has served your community.

Reputation

Spend time reading through online reviews, browsing the Better Business Bureau, and requesting local references. This will help confirm that the company consistently delivers quality work and professionalism. Take note of complaints describing poor service or faulty repairs.

Licensing and Insurance

Make sure any company you hire has the right licenses, bonds, and insurance for liability and workers' compensation. General contractors in California must be licensed by the Contractors State License Board before working on projects valued over $500. To apply for 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 law and business 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 concrete work.

Warranties

Pick a company that offers warranties of 10+ years that you can transfer to a new owner if you sell and, if possible, lifetime guarantees to fully back its work. This displays confidence that the company's work is top-notch and provides protection should problems come up later.

Questions To Ask Foundation Repair Companies

When comparing potential foundation repair companies, be sure to ask detailed questions such as:

  • How long will the repairs realistically take? Look for providers that provide reasonable estimates.
  • What foundation defects did you identify during inspection that may be causing the issue? The response should have easy-to-understand explanations and solutions. If a provider offers a vague answer, it may be trying to bill you for extra work.
  • What type of warranties do you offer? Reputable companies typically offer warranties of at least 10 years on labor and materials.
  • What repairs do you recommend for my situation, and why? Your contractor may offer options such as carbon fiber, steel piers, and wall anchors. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • Can you provide a complete written project scope and cost estimate? Asking for a quote in writing helps shield you from unexpected expenses.
  • What options do you have for financing? Many providers offer payment plans for larger foundation projects.

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 delivers durable, high-quality repairs. Promptly fixing foundation issues reduces the risk of further structural damage.

Frequently Asked Questions About Foundation Repair in Walnut, CA

If your foundation is in need of repair, it may manifest in a number of ways. 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 windows and doors that are sticking in their frames, or that the frames are skewed. You could also notice bowing, buckling, or cracking walls.

On average, Walnut homeowners spend around $2,704 on foundation repair. The total cost of foundation repair depends on a number of factors. Things like the size of your home, the extent of the damage, and the type of repair needed will all help determine the cost. The best way to learn how much a job might cost is to reach out to a local foundation repair expert and schedule a free inspection and estimate.

The main 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 contractor will perform an inspection and complete any repairs necessary to remedy cracks or leaks. The price will vary based on the size and cause of the issue.

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 used. The price of stabilization is also variable. This process reinforces bowing walls with carbon fiber or steel strips, and the cost will depend on what material is used and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs that help prevent water from getting into your foundation. This can involve interior waterproofing, exterior waterproofing, or both, and the price can vary widely. We recommend contacting a waterproofing specialist if you're planning to waterproof your foundation.

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

If you think there may be any problems with your foundation, you can reach out to a structural engineer for an evaluation. This will cost a few hundred dollars, but the consultation can net you a list of things to look out for as well as additional steps to further protect your foundation. Finally, if you're constructing a new house, ensure to have a soil report done. This report provides information regarding how well the soil on your property will be able to support a foundation and highlights 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 its process and to see the permits and paperwork it has acquired to ensure everything is properly authorized per Walnut regulations.

Although some foundation issues may seem small and not worth the cost to repair, when left untreated, they can cause much larger and more expensive problems down the road. Foundation problems may have underlying causes which are not readily apparent until after a professional inspection. It's important to handle these underlying issues as soon as possible. For these reasons, we recommend you don't procrastinate on foundation repairs.

The amount of time foundation repairs will take varies greatly based on the kind of repair required and the size of your home. Most repairs take anywhere from one to several weeks. Talk to your Walnut foundation repair expert for the specific timeline for your project.
