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.

From a single bathroom to a full-house renovation, we handle design, permits and construction for Mercer Island homes.
Custom kitchens for Mercer Island homes, planned around how you cook and gather and designed in 3D before demolition.
Primary suites, guest baths and spa showers, waterproofed and tiled by our own crews.
Composite and cedar decks, covered pavilions and outdoor living rooms built for Northwest weather.
Roof replacements and repairs with proper ventilation, flashing and drainage.
Siding, trim and exterior upgrades that protect the home and refresh its curb appeal.
Detached and attached living units, from drawings and permits to the finished space.
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.
Lakefront homes around the island’s shoreline, where views, moisture control and shoreline rules shape every project.
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.
