General contractor in Mercer Island
Hiring a general contractor on Mercer Island means one company is responsible for your whole project: the design, the permit, the trades and the final inspection. Renovision is a licensed design-build general contractor based in Bellevue, about 15 minutes away across the East Channel bridge. We work across the island, from the North End and East Seattle to Mercerwood and the South End.
Mercer Island homes range from 1950s and 1960s mid-century houses in Mercerwood and the North End to large waterfront properties along Lake Washington. Older homes often need an open kitchen, updated bathrooms and modern systems, and waterfront lots come with shoreline and tree-retention review. We scope each project around the house you actually have.
With a separate architect and builder, every design change becomes a new bid, a new drawing and a new delay. With a design-build general contractor, one team owns the result.
