How To Choose a Foundation Repair Company

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

Experience

Find a local foundation repair company with comprehensive experience fixing all foundation types. It should have expertise in the latest repair techniques and materials. Ask how long a company has served your area.

Reputation

Looking through online reviews, checking the Better Business Bureau, and requesting local references helps confirm that a company consistently provides quality work and good service. Pay attention if you see many complaints about faulty repairs or poor service.

Licensing and Insurance

It's important to select a provider that has valid credentials, bonding, 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. 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 warranties of 10+ years that you can transfer to a new owner if you sell and, if possible, lifetime guarantees to fully back its foundation repair services. This displays confidence that the company's work is top-notch and provides protection should problems come up later.

Questions To Ask Foundation Repair Companies

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

  • Can you provide a complete written project scope and cost estimate? Asking for a quote in writing helps shield you from unexpected expenses.
  • What type of guarantees do you offer? Trustworthy providers typically offer warranties of minimum 10 years on labor and materials.
  • What options do you have for financing? Providers often offer payment plans for larger foundation repairs.
  • What do you see as the likely cause of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide unclear answers may be attempting to bill you for unneeded work.
  • What exact repair method would you recommend for my specific situation and why? Your provider may offer options such as carbon fiber, steel piers, and wall anchors. Asking allows you to compare suggested solutions between companies.
  • How long will repairs realistically take to complete? Look for providers that provide reasonable estimates.

Carefully reviewing foundation repair companies will help you select the right one for you. Providers that can thoroughly answer these questions will likely deliver high-quality, durable repairs. Promptly addressing foundation issues helps avoid future structural damage.

Frequently Asked Questions About Foundation Repair in Issaquah, 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 basement or ground-level floors
  • Bowing, buckling, or cracked walls
  • Door frames or window frames that are skewed or tight
  • Cracks in your basement floor
  • Cracks in your driveway

On average, Issaquah homeowners spend around $3,041 on foundation repair. The amount you'll spend on foundation repair is based 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 factor in. The best way to find out how much a job could cost is to reach out to 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 complete any repairs necessary to remedy cracks or leaks. Costs will depend 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 price will be based on how many piers are required. The price of stabilization is also variable. This process reinforces bowing walls with carbon fiber or steel strips. 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 prevent water from getting into your foundation or basement. This can include exterior waterproofing, interior waterproofing, or both, and the price can vary greatly. We recommend contacting a waterproofing specialist if you're interested in waterproofing your foundation.

If you're building 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 give you a heads-up about potential future issues. If you have concerns about an existing home, a few hundred dollars will cover an inspection and report by a structural engineer. They can point you to any current problems that need attention, and give you advice on how to avoid future problems.

Also ensure that the moisture around your foundation is at an appropriate level. As Issaquah 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 pipes or gutters, so you can get them repaired quickly.

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 paperwork and permits it has acquired to verify that everything is properly authorized per Issaquah regulations.

Generally, foundation repairs will have a positive effect on the value of your home. In some cases, you may be able to consider foundation repair a capital improvement, which can sometimes help you qualify for tax breaks. A capital improvement is generally defined as one that adds to a home's overall value, prolongs its life, or adapts it to new uses. Speak with your Washington tax professional to learn more.

We recommend that you do not put off foundation repairs. A single issue may have an underlying cause that could lead to numerous future problems, and it's better to get ahead of the issue as soon as possible. A small and moderately costly problem now could turn into a large and expensive one in the future if the signs are ignored.
