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 to consider.

Experience

Choose a well-established local company with many years, ideally decades, of experience successfully handling all types of foundation repairs. These companies have specialized expertise with the latest methods and materials. Ask how long a company has served homes in your area.

Reputation

Spend time checking online reviews, browsing the Better Business Bureau, and requesting local references. This will help verify that a provider consistently delivers good workmanship and great customer service. Take note of any complaints describing faulty repairs or poor service.

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 are required to 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 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

Look for a company that provides transferable coverage for a minimum of 10 years, preferably lifetime guarantees, to back its foundation repairs. This demonstrates faith that its services are top-quality and safeguards you if issues come up in the future.

Questions To Ask Foundation Repair Companies

When examining potential foundation repair companies, make sure to ask in-depth questions such as:

  • What exact repair method do you recommend for my specific situation and why? Your provider 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.
  • How long will repairs realistically take to complete? Look for companies that provide reasonable estimates.
  • What guarantees do you provide? Reliable companies usually provide labor and materials warranties of at least 10 years.
  • What financing options do you offer? Providers often offer payment plans for larger foundation repairs.
  • What are some likely causes of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide vague answers may be attempting to bill you for extra work.
  • Can you provide a complete written project scope and cost estimate? Getting the details in writing helps shield you from unexpected costs.

Taking the time to review foundation repair companies helps homeowners identify the ideal match for their needs. A provider that can answer the questions above is likely one that offers long-lasting, durable repairs. Promptly fixing foundation problems helps avoid further structural damage.

Frequently Asked Questions About Foundation Repair in Mill Valley, CA

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

On average, Mill Valley homeowners pay roughly $2,882 for foundation repair, although the total cost will vary widely depending on several factors. The fastest way to estimate the cost of your specific project is to request quotes from a handful of local foundation repair companies. Your total cost will be influenced by things like the size of your house and type of repair(s) needed.

The main types of foundation repair include 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 vary based on the size and cause of the problem.

Underpinning, also called piering or leveling, is when a contractor levels your foundation by underpinning it with large concrete piers. The price will be based on how many piers are needed. The price of stabilization varies similarly. This process fixes bowing walls by reinforcing them with steel or carbon fiber strips, and the total cost will depend on the material chosen and how many strips are used.

Lastly, waterproofing is an overarching term for a number of jobs intended to prevent water from getting into your foundation. This can include 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.

To protect your foundation, you should make sure it has the right amount of moisture. Avoid letting the soil around your Mill Valley house become too wet or too dry – make changes to your gutter system to route water away, or water your foundation if it starts to get too dry. Also be sure to quickly identify and fix any leaking pipes or gutters.

If you have any concerns about your foundation, you can call a structural engineer for an evaluation. This will run you a few hundred dollars, but the engineer's consultation can net you a list of things to look out for as well as more ideas to help you further protect your foundation. Finally, if you're constructing a new home, be sure to have a soil report done. This report provides information about how well the soil on your property will be able to support a foundation and highlights any potential future problems.

Permits are needed for most foundation repairs, but acquiring one shouldn't be your responsibility. Your foundation repair professional should obtain the permit and all other documents required in Mill Valley, and should be able to provide the documents and/or explain the process before starting work.

Foundation repair, especially large repairs like basement waterproofing, should last a long time. This is particularly true if you use a reliable company. By solving systemic issues with your foundation, or reinforcing important areas, you reduce the risk of future problems.

In general, foundation repair projects will take from one to several weeks. This range is large because the time taken will vary greatly based on factors like the type of repair required and the size of your home. You should consult with your Mill Valley foundation repair expert for a more thorough timeline for your specific project.
