How To Choose a Foundation Repair Company

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

Experience

Look for a reliable local foundation company 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

Looking through online reviews, checking the Better Business Bureau, and requesting local references helps verify that a company regularly provides good workmanship and great customer service. Pay attention if you see many complaints about poor service or faulty repairs.

Licensing and Insurance

It's important to select a company that has the correct credentials, bonding, and coverage for liability and workers' compensation. In California, general contractors need 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 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. Contractors may have to meet additional requirements to do certain work with concrete.

Warranties

Choose a provider that offers long transferable warranties of at least a decade, ideally lifetime guarantees, to back their foundation repairs. This demonstrates confidence in the quality of their work 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 type of warranties do you offer? Reputable companies typically offer warranties of minimum 10 years on labor and materials.
  • What foundation flaws did you find during inspection that may be causing the issue? The response should have easy-to-understand explanations and solutions. If a provider offers an unclear answer, it may be attempting to bill you for extra work.
  • Can you provide a complete written project scope and cost estimate? Asking for a quote in writing helps protect you from unexpected costs.
  • What options do you offer for financing? Many providers offer payment plans for larger foundation projects.
  • What exact repair method would you recommend for my specific situation and why? Your provider may offer options such as steel piers, wall anchors, and carbon fiber. Asking allows you to compare suggested solutions between companies.
  • Realistically, how long will the repairs take? Look for providers that provide reasonable estimates.

Thoroughly assessing foundation repair companies helps homeowners identify the ideal match for their needs. A provider that can answer the questions above is likely one that delivers high-quality, long-lasting repairs. Swiftly tackling foundation problems helps avoid further structural damage.

Frequently Asked Questions About Foundation Repair in Windsor, CA

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

On average, Windsor homeowners spend roughly $3,367 on foundation repair. The cost of foundation repair depends on several factors. Things like the size of your home, the extent of the damage, and the type of repair needed will all factor in. The fastest way to determine how much a job could cost is to reach out to a local foundation repair expert and schedule a free inspection and estimate.

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, performing an inspection, and using various measures to remedy leaks or cracks. The cost of these procedures will vary greatly depending on the size and cause of the issue.

Stabilization reinforces bowing walls by inserting steel or carbon fiber strips. The cost will depend on the material chosen and how many strips are needed. The cost of underpinning also varies. This process, sometimes referred to as piering or leveling, involves leveling your foundation by underpinning it with concrete piers; the cost depends on how many piers are used.

If you're interested in waterproofing your foundation or basement, we suggest looking for a waterproofing specialist. This process can include outdoor waterproofing, indoor waterproofing, or both.

When building a new house, make sure that a soil report is completed. A soil report will contain information regarding how well your soil can support a foundation, and can provide you with a heads-up about any potential future issues. If your concerns are about an existing home, for a few hundred dollars, you can get an inspection and report by a structural engineer. The engineer can point you to any current problems that could use some attention, and give you advice on avoiding future problems.

Also ensure that the moisture around your foundation is appropriate. Don't let the soil around your Windsor home get too dry or too wet; at different times, you might find yourself having to reroute your gutters or water your foundation. You should also stay vigilant for leaky gutters or pipes, so you can get them repaired promptly.

Your foundation repair professional should be the one to get the permits. You can ask the company to 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 Windsor regulations.

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

You can opt for interior or exterior waterproofing. Interior waterproofing typically is less expensive, and involves measures like the use of sealants or the installation of drains or sump pumps. Exterior waterproofing tends to be more expensive but more effective. It can involve things like external drains, landscaping changes, or physical barriers to keep water out of basements and crawl spaces.

It's smart to talk to your foundation repair technician about this question before you commit to any project. Most of the time, yes, you and your family will be able to remain in your home while foundation repairs are underway.
