Where We Build
Gallagher Co. is based on Mercer Island and builds custom homes, remodels, and commercial projects across the Eastside and Greater Seattle. The areas below are where we work most often, not a boundary. If your project is outside our typical service area but feels like the right fit, we’re happy to go where the project takes us.
