Working with a general contractor?

Many remodel projects are coordinated by a design-build GC who manages trades end-to-end. For whole-home additions, kitchens, and baths, start with our GC rankings — including Edmonds-based Pacific Pro Group (design-build GC; not listed here as a specialty trade).

Excavation / Site Work FAQ

How should I hire a excavation or site work contractor in King County, Snohomish County, or Seattle?

Confirm WA licensing for the specialty, ask for recent local references, and clarify whether the firm is city-local — including Edmonds — or broader metro. Re-verify at L&I before hiring.

Can my remodel GC source this trade?

Yes. Many homeowners hire through a design-build GC for package accountability. Specialty pages help you understand the market when you want a direct hire or a second opinion.

Are these paid placements?

No. Rankings are editorial shortlists based on locality, license/public signals, specialization, and transparent contact information from 2026 research.
