Best 5 Foundation Repair Companies in Sammamish, WA

Common Causes of Foundation Problems in Sammamish

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

• Soil composition: Soil with large sand or clay concentrations is highly expansive. In the heavy rainfall Sammamish gets, 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 keep dry.
• Aging plumbing: While many Sammamish homes are fairly new, some still use cast-iron plumbing. When the pipes start to erode, leaking water could reach your foundation and even pool beneath it.
• Standing water: Standing water around your home can be menacing to your foundation, especially when it gathers in areas your gutters don't reach.
• Improper modifications: Landscaping or roofing work that wasn't performed to standard could lead to your foundation settling.
• Tree Roots: Tree roots can encroach on a home's foundation through cracks, and may apply force that results in your foundation cracking, pipes rupturing, and overall structural weakening.

How to Choose the Best Foundation Repair Company

Choosing a foundation company doesn't have to be complicated. We encourage you to list what you expect most in a provider, then evaluate each contractor on your selection against these characteristics.

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. To further understand your contractor's experience, we recommend asking questions about what local codes apply to your project, how the company inspects foundations, and how its team will draft plans and pull permits.

Contractor websites are among the best places to do your research. Usually, a business will disclose how long it's been in business. It might also share other content to help interested parties.

Customer Reviews

We suggest looking into 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 expressed satisfaction or filed complaints. Pay special attention to what customers say about company warranties. Complaints aren't necessarily a red flag in themselves. Instead, discover how a company handles them. If the management team consistently and proactively resolves issues, it's a good sign. However, if the company lacks accreditation, has more negative reviews, and doesn't communicate effectively, you should think twice about working with it.

Lastly, we encourage you to search additional sites, such as Trustpilot and Google, for other reviews.
