Home Addition Contractor in Seattle, WA

Yes. Seattle is about 55 miles north of our base in Rainier, well inside our 100-mile service area. Greg handles room additions, primary suites and second-story additions there, and the estimate is free.

It depends on the project. When one is needed, Greg pulls the permit from the City of Seattle's building department and builds to whatever the permit and inspection require.

It depends mostly on size, whether it is a ground-level or second-story addition, and what goes inside it, since bathrooms and kitchens take more work per square foot than bedrooms. Site conditions, the foundation and how much of the existing house has to change also play in. Greg prices each addition after a free on-site visit.

Both do. Clay and glacial till soils drain poorly and high water tables are common, so footing drains and grading away from the house matter. The rainy season also shapes the schedule, so we aim to get the frame roofed and wrapped quickly to keep the inside dry.

Building out is usually simpler when you have the yard, and the rest of the house stays livable during the work. Building up makes sense on a tight lot or when you want to keep the yard, but the existing foundation and walls have to be checked for the extra weight. Greg will look at both options at the estimate.

Yes. Every addition needs a building permit, and rural lots can also bring setback, critical-area and septic capacity questions when you add a bedroom. Greg handles the permit and inspections with your county or city.
