About the service

Remodeling for Island Homes

Mercer Island is known for its waterfront homes, established neighborhoods and estate properties. NW Expert Builders designs and builds kitchens, bathrooms, additions and whole-home remodels on the island, with every room planned in 3D before work begins.

From lakefront homes to mid-century houses on quiet, tree-lined streets, island homes often need more than new finishes. We plan around views, light and the lake’s damp air, and update plumbing, electrical and ventilation behind the walls so the new rooms last.

Close to the shoreline, projects can require extra review before a permit is issued. We plan for that from the first visit, so the schedule you see is the one we keep.

Remodeling across Mercer Island.

From our Redmond office we work in homes throughout Mercer Island. Every neighborhood brings its own homes, lots and rules, and we plan each project around them.

  • Waterfront homes

    Lakefront homes around the island’s shoreline, where views, moisture control and shoreline rules shape every project.

  • Established neighborhoods

    Mid-century and classic homes on quiet, tree-lined streets, often ready for open layouts and modern kitchens and baths.

    Large homes on generous lots, where whole-home remodels, primary suites and outdoor living bring the house up to its setting.
