Construction Services Seattle — One Contractor, Multiple Trades

Bad Boyz GC LLC provides comprehensive construction services in Seattle and the greater King County area. Unlike most contractors who subcontract every trade, our in-house crews handle the full scope of work — from demolition and excavation to framing, drywall, painting, and finish carpentry. One contractor, one team, one standard of quality.

Whether you need a custom home built from the ground up, a full renovation of your existing property, a commercial buildout for your business, or specialty trade work like drywall installation or metal framing, we have the experience and the crew to get it done right.

Our construction services Seattle homeowners and businesses trust cover every phase of the building process. Explore our service categories below and contact us for a free estimate on your project.
