How To Choose a Foundation Repair Company

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

Experience

Look for a reputable local foundation provider with many years of successfully fixing a wide range of foundation problems. Technicians should have extensive experience with current repair methods and materials. Contact the company to ask how long it’s served your community.

Reputation

Carefully reading online reviews, checking the Better Business Bureau, and asking for local references helps confirm that a provider consistently delivers high-quality work and great service. Pay attention to any complaints about shoddy repairs or poor service.

Licensing and Insurance

Only hire companies that are properly licensed, bonded, and have both liability and workers compensation insurance. Washington does not have 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. Make sure to check with your city or county government to learn about any additional local requirements. There may be additional requirements for contractors to do certain work with concrete.

Warranties

Pick a company that offers long transferable warranties for a minimum of 10 years and, if possible, lifetime guarantees to fully back its foundation repair services. This displays faith that their repairs will be high-quality and long-lasting and provides protection if problems come up later.

Questions To Ask Foundation Repair Companies

To compare foundation repair companies, you should ask specific questions such as:

  • What options do you offer for financing? Many providers offer payment plans for larger foundation projects.
  • Realistically, how long will the repairs take? Look for providers that provide reasonable estimates.
  • 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 trying to bill you for extra work.
  • What repairs would you recommend for this situation, and why? Your contractor may offer options such as steel piers, carbon fiber, and wall anchors. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What type of warranties are provided? Reputable companies often offer warranties of minimum 10 years on materials and labor.
  • Can you provide a complete written cost estimate and project scope? Getting quotes in writing helps protect you from unexpected costs.

Taking time to carefully evaluate foundation repair contractors will help homeowners find the right company for their needs. A company that can thoroughly answer these questions is likely one that delivers high-quality, long-lasting repairs. Promptly fixing foundation issues reduces the risk of further structural damage.

Frequently Asked Questions About Foundation Repair in Federal Way, WA

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

On average, Federal Way homeowners spend around $3,042 on foundation repair. The total cost of foundation repair depends on several factors. Things like the extent of the damage, the type of repair needed, and the size of your home will all help determine the cost. The easiest way to determine how much a job could cost is to speak with a local foundation repair expert and schedule a free inspection and estimate.

The primary types of foundation repair include crack repair, leak repair, underpinning, stabilization, and waterproofing.

Crack repair and leak repair are exactly as they sound: your foundation repair expert will perform an inspection and take necessary measures 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 when a contractor levels your foundation by underpinning it with large concrete piers. The cost will depend on how many piers are required. The price of stabilization is also variable. This process fixes bowing walls by reinforcing them with steel or carbon fiber strips. The cost will depend on the material chosen and how many strips are used.

Lastly, waterproofing is an overarching term for a category of repairs intended to prevent water from getting into your foundation or basement. This can include interior waterproofing, exterior waterproofing, or both, and the price can vary widely. We recommend contacting a waterproofing specialist if you think your foundation needs waterproofing.

If you're constructing a new house, have a soil report completed. A soil report will contain information regarding how well your soil can support a foundation, and can offer you a heads-up about potential future issues. If your concerns are about an existing house, 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 need attention, and give you advice on how to avoid future problems.

You also want to make sure that the moisture around your foundation is appropriate. As Federal Way 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 and repair them promptly.

A permit is normally required for foundation repair, but getting one shouldn't be your responsibility. Your foundation repair professional should obtain all the permits and other documents required in Federal Way, and should be able to provide the documents and/or explain the process before starting work.

Some indicators that your foundation needs waterproofing include basement flooding, discoloration or odors, white powder or spots on your walls, uneven floors, hairline cracks, or signs of mildew, fungus, or mold. Your contractor can tell you whether you need interior or exterior waterproofing.

Interior waterproofing can involve the use of sealants or the installation of sump pumps and drains and generally is less costly than exterior waterproofing. Exterior waterproofing can involve applying physical barriers to basements and crawl spaces, making landscape changes, or installing exterior drains.

You may not want to spend money hiring someone for what seems like a small foundation repair. However, it's always good to consult a professional. This helps you avoid more expensive issues down the road. It may be possible to fix small hairline cracks yourself, but it's always in your best interest to get an expert opinion first.
