Common Causes of Foundation Problems in Seattle

A few factors can contribute to foundation issues. These are the most widespread ones for Seattle residents:

  • Soil composition: Soil with large clay or sand concentrations is highly expansive. In the heavy rainfall Seattle gets, the soil soaks up moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction presses against nearby foundations, even if the foundations stay dry.
  • Standing water: Pooling water around your home can be a menace to your foundation's integrity, especially when it collects in areas your drainage system doesn't cover.
  • Aging plumbing: The average Seattle home construction year is 1968. If you live in an older home, it's likely to have cast-iron plumbing. When the pipes start to erode, leaking water could reach your foundation and even pool beneath it.
  • Tree Roots: Tree roots can enter a home's foundation through cracks, and may exert pressure that leads to your foundation fracturing, pipes rupturing, and overall structural deterioration.

How to Choose the Best Foundation Repair Company

When choosing a foundation repair company, you should consider your personal priorities. Ask each provider on your list about the following qualities.

Licensing and Experience

Washington foundation repair companies can be either general or specialty contractors. Look for companies with a concrete certification, showing that they follow best practices in the foundation field. You can also get a sense of a company's experience through the details its representatives share. Inquire about its inspection methods, local building regulations, permit-pulling procedures, and fees.

Contractor websites are excellent places to do your research. Typically, a business will mention how long it's been in business. It might also upload blog posts to assist potential clients.

Customer Reviews

Before selecting a company, examine its online profile with the Better Business Bureau (BBB). You can examine both positive reviews and complaints. Complaints aren't necessarily a red flag in themselves. You want to discover how a company responds to them. If the management team consistently and proactively resolves issues, it's a good sign. However, if the company lacks accreditation, shows more negative reviews than positive ones, and doesn't communicate properly, you should think twice about working with it.

Lastly, we suggest you search additional sites, like Trustpilot and Google, for other reviews.

Foundation Repair Cost in Seattle

Foundation repair costs can range quite widely based on the degree of the problems and what must be done to fix them. For minor foundation fissuring and settling problems, you may pay as little as $1,800. However, if there is significant damage, the normal cost will be around $3,000. More intricate jobs involving digging, helical piers, or major concrete leveling could run you $6,900. See below the average foundation repair costs for common issues.

Frequently Asked Questions About Foundation Repair in Seattle

What will I pay to repair my foundation in Seattle?

You could spend about $3,000 on materials and labor for your foundation project. Ultimately, your costs will depend on your specific needs and the extent of the damage.

What's the time to complete a typical foundation repair job?

The time to complete a foundation repair job usually depends on the extent of the damage, the contractor's efficiency, and the repair method used. Foundation repairs can take just a few days for minor issues to several weeks for more extensive problems. It's crucial to consult with a specialist to get a more accurate estimate for your specific situation.

Will my homeowners insurance cover foundation repair?

Sometimes. Whether you'll have coverage depends on the kind of insurance you have and the cause of the foundation damage. Earthquake or flood insurance will typically cover foundation damage caused by those specific disasters. Homeowners insurance can cover damage from other disasters, but will not cover normal wear and tear. We recommend speaking with your insurance agent about the extent of your policy and how to file a claim.

What preventive measures can I take to avoid foundation issues?

You can take several preventive measures to minimize foundation issues:
  • Make sure your home's gutters and downspouts are properly installed and direct water away from your foundation to prevent water accumulation.
  • Irrigate the soil around your foundation consistently, especially during dry spells, to prevent expansion and shrinking.
  • If possible, grade the soil around your home to angle away from your foundation, promoting water drainage and minimizing the risk of foundation issues.
  • Keep an eye on your foundation for cracks, and address any issues promptly.
