How To Choose a Foundation Repair Company

You need a good foundation repair contractor to accurately evaluate issues and make appropriate repairs. Do thorough research and focus on these key factors when looking for the right company.

Experience

Look for a reliable 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 materials and methods. Contact the company to ask how long it’s served your community.

Reputation

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

Licensing and Insurance

Only hire companies that are properly licensed, bonded, and have both liability and workers compensation insurance. In Washington, there are no state-level licensing requirements for contractors, but they must register with the Washington State Department of Labor & Industries. Registration requires contractors to be bonded and insured. You can check with your city, county, or municipal government to find out if there are any additional local requirements. Contractors may have to meet additional requirements to do certain concrete work.

Warranties

Look for a provider that offers lengthy transferable warranties for a minimum of a decade, preferably lifetime guarantees, to back its work. This demonstrates faith that its services are top-quality and safeguards you if issues arise in the future.

Questions To Ask Foundation Repair Companies

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

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

Taking time to vet foundation repair companies will help you locate the right one for you. Providers that can thoroughly answer these questions will likely offer durable, high-quality repairs. Promptly addressing foundation issues helps prevent future structural damage.

Frequently Asked Questions About Foundation Repair in Seattle, WA

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

On average, Seattle homeowners pay about $3,041 for foundation repair, although the actual cost will depend on several factors. The easiest way to get an estimate for the cost of your specific project is to ask for quotes from a handful of local foundation repair companies. Your total cost will be affected by things like the type of the repair(s) and the size of your house.

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, perform an inspection, and use various repair techniques to remedy leaks or cracks. The cost of these procedures can vary greatly depending on the size and root cause of the issue.

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

If you're looking to waterproof your foundation or basement, we recommend talking to a waterproofing specialist. This process can include outdoor waterproofing, indoor waterproofing, or both.

If you're building a new home, make sure that a soil report is completed. This report contains information about how well the soil on a given piece of land can support a foundation, and can give you a heads-up about potential future problems. If you have concerns about an existing house, a few hundred dollars will cover an inspection and report by a structural engineer. The engineer can alert you to any things that need attention, and give you advice on avoiding future problems.

It's also important that the moisture around your foundation is appropriate. As Seattle 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. Also, be on the lookout for leaky gutters or pipes, so you can get them repaired promptly.

Your foundation repair professional should be the one obtaining the permits. You can ask the company to provide a detailed explanation of the steps in its process and to see the permits and paperwork it has assembled to make sure everything is properly authorized per Seattle regulations.

It's smart to talk to your foundation repair professional about your concerns before starting any project. In most cases, yes, you and your family will be able to remain in your home while foundation work is being done.

In general, foundation repairs will have a positive effect on your home's value. In some cases, foundation repairs may be considered a capital improvement, which might allow you to qualify for tax breaks. Generally, a capital improvement is defined as one that will add to your house's overall market value, prolong its life, or adapt it to new uses. Speak with your Washington tax professional for more information.
