Washington

Serving the Evergreen State since 1997

Washington’s diverse terrain—from coastal lowlands to mountainous regions—features a mix of loamy, silty, and clay soils that, combined with heavy rainfall and seismic activity, often lead to foundation settlement, basement moisture problems, and crawl space deterioration. Frequent wet weather and shifting ground conditions also contribute to unlevel and cracking concrete surfaces around homes. Groundworks proudly serves homeowners across Washington with expert solutions in foundation repair, basement waterproofing, crawl space encapsulation and repair, and concrete lifting and leveling. Backed by BBB A+ accreditation and a team of certified field inspectors offering free, no-obligation inspections, we provide permanent, customized repairs designed for Washington’s challenging environmental conditions. From Seattle to Spokane and Tacoma, Groundworks is your trusted partner in protecting your home from the ground up.
