City of Mercer Island

Federal Way (Headquarters)

Mercer Island's plumbing work is defined by two things: the water, and the wholesale rebuilding of its mid-century housing. The 1950s–'70s ramblers and split-levels of First Hill, Mercerdale, Lakeridge, and the South End are being remodeled or replaced outright at a remarkable pace, and behind those walls sits original galvanized supply pipe, cast-iron drain lines, and side sewers that were never meant to serve a modern kitchen and four baths. We repipe these homes in PEX and copper as part of larger remodels or on their own, coordinating with your contractor and keeping the work clean enough for a home you're still living in.

The waterfront homes of the North End, East Seattle, Faben Point, and the West Mercer shoreline ask more of their plumbing than almost anywhere else in the region: recirculating hot water so the far bathroom is instant, multiple or commercial-grade water heaters, steam showers, high-flow fixtures, dock water lines, and irrigation that all need correct pressure on steep lots. Mercer Island's sewer trunk runs along the lakeshore, so many waterfront homes' side sewers run downhill to it — and some rely on grinder pumps that need periodic service.

Water and sewer are both provided by the City of Mercer Island, with soft Seattle Public Utilities supply, so scale is rarely the issue; age, pressure, and slope are. The Town Center has added condos and mixed-use buildings around the light-rail station that need commercial-grade service and building-management coordination.

Permits for water heaters, gas piping, repipes, and side sewers go through Mercer Island Community Planning and Development, and we pull and manage them for you. Mercer Island is about 30 to 40 minutes from our Federal Way headquarters via I-405 and I-90 outside of peak traffic. Scheduled service is booked in confirmed arrival windows, and 24/7 emergency dispatch is always available. Every job ends with floors protected, dust contained, and a walkthrough of exactly what we did.
