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 Sammamish

A home in Sammamish might experience foundation issues for multiple reasons. Some are specific to the local environment, while others are common nationwide. They include:

  • Soil composition: Soil with large sand or clay concentrations is highly expansive. In the heavy rainfall Sammamish gets, the soil absorbs moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction stresses nearby foundations, even if the foundations keep dry.
  • Standing water: Water accumulation around your home can threaten your foundation's integrity, especially when it gathers in areas your gutters don't reach.
  • Improper modifications: Roofing or landscaping work that wasn't performed to standard could result in your foundation settling.
  • Tree Roots: Tree roots can intrude into a home's foundation through crevices, and may create stress that causes your foundation breaking, pipes being damaged, and overall structural deterioration.

How to Choose the Best Foundation Repair Company

Choosing a foundation provider doesn't have to be difficult. We encourage you to jot down what you want most in a company, then evaluate each contractor on your shortlist against these attributes.

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. Talk to representatives to gain further insight into a company's experience. You should ask about local inspection processes, building codes and permit ordinances.

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

Customer Reviews

We advise reviewing the company's Better Business Bureau (BBB) profile to see whether it's accredited and has a high customer review score. You can see whether other homeowners have reported satisfaction or filed complaints. Pay special attention to what customers say about company warranties. Negative feedback doesn't mean a contractor is bad news. BBB reviews show how the company dealt with complaints. It's a good sign if the company has fixed issues proactively and favorably. You should stay away from a company with numerous negative reviews, no credentials, and no communication regarding issues.

Foundation Repair Cost in Sammamish

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 cracking and settling concerns, you may pay as little as $1,800. However, if there is quite substantial destruction, the typical cost will be around $3,000. More intricate jobs involving digging, helical piers, or major concrete leveling could run you $6,900. Below are the average foundation repair costs for common issues.

Frequently Asked Questions About Foundation Repair in Sammamish

What will I pay to repair my foundation in Sammamish?

Foundation repair costs about $3,000 in Sammamish. The final numbers hinge on how severe the damage is and what type of repair you need.

When do I need to waterproof my foundation?

You'll typically need to waterproof your foundation when you see any of these signs:

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 avoid 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, encouraging water drainage and minimizing the risk of foundation issues.
  • Inspect your foundation for signs of damage, and fix any issues promptly.

What are some "red flags" indicating a foundation company to avoid?
