How To Choose a Foundation Repair Company

You need a good foundation repair contractor to properly assess issues and make appropriate repairs. Do your research and focus on these factors when looking for the right company.

Experience

We recommend hiring a local foundation repair company with a long history of fixing various types of foundations. These companies should have deep knowledge of the latest techniques and materials. Ask providers how long they've served your area.

Reputation

Spend time checking online reviews, browsing the Better Business Bureau, and asking for local references. This will help confirm that the company consistently delivers quality work and professionalism. Take note of any complaints mentioning faulty repairs or poor service.

Licensing and Insurance

Make sure any company you hire has the right credentials, bonds, and coverage for liability and workers' compensation. There are no state-level licensing requirements for contractors in Washington, but all must register with the Washington State Department of Labor & Industries. To register, contractors must be bonded and insured. Make sure to check with your city, county, or municipal government to learn about any additional local requirements. There may be additional requirements for contractors to do certain concrete work.

Warranties

Choose a company that offers 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 in case of future issues.

Questions To Ask Foundation Repair Companies

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

  • What financing options do you offer? Many providers offer payment plans for larger foundation projects.
  • What foundation flaws 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 an unclear answer, it may be attempting to bill you for extra work.
  • Can you provide a complete written cost estimate and project scope? Getting the details in writing helps protect you from unexpected expenses.
  • What warranties do you provide? Reliable companies generally provide labor and materials warranties that last at least 10 years.
  • What repairs do you recommend for this situation, and why? Your contractor may offer options such as wall anchors, steel piers, and carbon fiber. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • How long will the repairs realistically take? Look for providers that provide reasonable estimates.

Taking time to carefully evaluate foundation repair contractors will help homeowners discover the right company for their needs. A company that can thoroughly answer these questions is likely one that provides durable, high-quality repairs. Promptly fixing foundation issues helps prevent further structural damage.

Frequently Asked Questions About Foundation Repair in Alderwood Manor, WA

There are a variety of signs that your foundation is in need of repair. These might include:

  • Visible crumbling or cracks in your foundation
  • Uneven ground-level or basement floors
  • Cracked, bowing, or buckling walls
  • Door frames or window frames that are skewed or tight
  • Cracks in your basement floor
  • Cracks in your driveway

On average, Alderwood Manor homeowners spend about $3,018 on foundation repair. The total cost of foundation repair will vary greatly depending on a number of factors. Things like the size of your home, the type of repair needed, and the extent of the damage will all play a part. The best way to find out how much a job is going to cost is to reach out to a local foundation repair expert and schedule a free inspection and estimate.

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 take necessary measures to remedy cracks or leaks. Costs will vary based on the size and cause of the issue.

Underpinning, also called piering or leveling, is the process of leveling 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 involves fixing bowing walls by reinforcing them with steel or carbon fiber strips, and the total cost will depend on what material is used and how many strips are used.

Lastly, waterproofing is an overarching term for a number of jobs intended to stop water from getting into your foundation or basement. This can include exterior waterproofing, interior waterproofing, or both, and costs can vary widely. We recommend contacting a waterproofing specialist if you're interested in waterproofing your foundation.

When caring for your foundation, you should make sure it gets the right amount of moisture. Alderwood Manor sees more rain than many places, so be sure that your gutters and landscaping are arranged to prevent too much water from collecting near your foundation. Also be sure to promptly identify and fix any leaking gutters or pipes.

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

Your foundation repair expert should acquire the needed 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 ensure everything is properly authorized per Alderwood Manor regulations.

Small hairline cracks might seem easy to handle on your own, but in general, you should consult a professional before beginning any kind of foundation work. While you may balk at the idea of paying someone for work you feel like you can handle yourself, mistakes made during foundation repair can cost you much more in the future.

We strongly suggest contacting your home insurance provider before beginning any foundation project to learn about what might be covered. Typically, foundation repairs won't be covered by home insurance unless they're to repair damage caused by a covered weather event.
