This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

Common Causes of Foundation Problems in Issaquah

A few common reasons why Issaquah homeowners encounter foundation problems include:

  • Improper modifications: Landscaping or roofing work that wasn't completed to standard could lead to your foundation settling.
  • Standing water: Water accumulation around your home can threaten your foundation's integrity, especially when it gathers in areas your gutter system doesn't protect.
  • Aging plumbing: While many Issaquah homes are fairly new, some still use cast-iron plumbing. When the pipes start eroding, leakage could reach your foundation and even pool beneath it.
  • Soil composition: Soil with large sand or clay concentrations is highly expansive. In the heavy rainfall Issaquah experiences, the soil soaks up moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction stresses nearby foundations, even if the foundations stay dry.
  • Tree Roots: Tree roots can encroach on a home's foundation through crevices, and may exert pressure that results in your foundation fracturing, pipes rupturing, and overall structural weakening.

How to Choose the Best Foundation Repair Company

Your home's integrity weighs heavily on its foundation. It's essential to select the best team possible. Focus your research on these 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 processes, local codes, permit-pulling procedures, and fees.

Another way to determine a company's standing is to examine its website. There, you can learn how long it's been in business and its trade qualifications. It might also share knowledge and insights through blog posts, podcasts, or videos.

Customer Reviews

When you're researching a company's standing, visit its Better Business Bureau (BBB) profile. There, you can find its "letter grade" rating and a list of customer reviews, both positive experiences and complaints. Complaints don't mean a contractor is unreliable. BBB reviews show how the company dealt with complaints. It's a positive sign if the company has fixed issues favorably and proactively. You should steer clear of a company with numerous negative reviews, no certifications, and no communication regarding issues.

Foundation Repair Cost in Issaquah

The price of foundation repair can vary substantially depending on the extent of the issues and what's needed to resolve them. For minor foundation fracturing and settling issues, you may pay as little as $1,800. However, if there is significant deterioration, the normal cost lands at about $3,000. More involved projects involving excavating, helical piers, or major mudjacking could cost upwards of $6,900. See below the average foundation repair costs for common issues.
