How To Choose a Foundation Repair Company

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

Experience

Look for a reputable local foundation provider with a proven history of successfully fixing foundations. Technicians should have expert-level understanding of current repair materials and methods. Contact the company to ask how long the business has served your community.

Reputation

Reading through online reviews, checking the Better Business Bureau, and asking for local references helps you verify that a company consistently delivers good workmanship and a positive customer service experience. Pay attention if you see multiple complaints about poor service or faulty repairs.

Licensing and Insurance

Choose a provider that has the right licenses, bonds, and coverage plans for liability and workers' compensation. In Washington, there are no state-level licensing requirements for contractors, but all must register with the Washington State Department of Labor & Industries. To register, contractors must be bonded and insured. You can check with your city or county government to learn about any additional local regulations. There may be additional requirements for contractors to do certain concrete work.

Warranties

Pick a company that offers transferable warranties for a minimum of a decade and, if possible, lifetime guarantees to fully back its work. This displays confidence that the company's work is top-notch and provides protection if problems come up later.

Questions To Ask Foundation Repair Companies

As part of your research into foundation repair providers, get detailed answers to questions such as:

  • What repairs would you recommend for my situation, and why? Your contractor may consider options such as steel piers, carbon fiber, and wall anchors. Asking allows you to compare suggested solutions between companies.
  • What foundation defects did you identify during inspection that could 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.
  • Realistically, how long will repairs take to complete? Look for providers that provide reasonable estimates.
  • What options do you have for financing? Many providers offer payment plans for larger foundation projects.
  • Can you provide a project scope and cost estimate in writing? Be sure to get quotes in writing to shield yourself from unexpected expenses.
  • What type of guarantees are provided? Trustworthy providers typically offer warranties of at least 10 years on labor and materials.

Thoroughly evaluating foundation repair companies will help you select the right one for you. Providers that can thoroughly answer these questions will likely deliver durable, high-quality repairs. Swiftly fixing foundation issues helps prevent future structural damage.

Frequently Asked Questions About Foundation Repair in Redmond, WA

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

On average, Redmond homeowners spend about $3,042 on foundation repair. The amount you'll spend on foundation repair depends on a number of factors. Things like the type of repair needed, the extent of the damage, and the size of your home will all help determine the cost. The best way to learn how much a job may cost is to reach out to a local foundation repair company 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 can vary greatly depending on the size and root cause of the issue.

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

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

If you're constructing a new house, have a soil report 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 issues. If your concerns are about an existing house, a few hundred dollars will cover an inspection and report by a structural engineer. They can alert you to any things that could use some attention, and advise you on avoiding future problems.

You also want to make sure that the moisture around your foundation is appropriate. As Redmond sees more rain than many other places, keep an eye on your gutters and landscaping to make sure too much water isn't getting into your soil or foundation. You should also stay vigilant for leaky gutters or pipes, so you can get them repaired quickly.

Your foundation repair expert should be the one to get the permits. You can ask the company to provide a detailed explanation of its process and to see the permits and paperwork it has acquired to verify that everything is properly authorized per Redmond regulations.

In most cases, yes, you can continue living in your home while foundation repair work is being completed. You can ask your foundation repair technician to know for sure.

Foundation repair, particularly extensive repairs such as basement waterproofing, should last a long time. This is particularly true if you use a reputable company. By solving systemic foundation issues, or reinforcing important areas, you reduce your risk of future problems.
