Whole-Home Repiping
Bainbridge Island has a substantial stock of homes built in the 1960s through 1980s that still have original galvanized steel supply lines. If your home is showing signs of internal corrosion — discolored water, declining pressure, recurring leaks — a full repipe may be the most cost-effective long-term answer. See our whole-home repiping page for a full breakdown of what’s involved.
New Construction Plumbing on Bainbridge Island
Bainbridge Island’s custom home market is active, and the plumbing on a new build sets up everything that follows. A poorly sized water supply line, rough-in that doesn’t account for future fixture placement, or a drain stack that’s off-center by two inches creates problems that are expensive to fix once walls are closed. Getting the plumbing right at the rough-in stage protects the entire project.
Costanza Plumbing provides complete
new construction plumbing services for Bainbridge Island custom homes and residential developments, including:
- Underground rough-in — water supply and drain/waste/vent below the slab or in the crawl space
- Above-ground rough-in — supply and DWV framing stage work, coordinated with structural framing and inspection schedules
- Top-out — completing vent stack penetrations and all above-ceiling rough work before insulation and drywall
- Finish plumbing — fixture trim-out, water heater connection, appliance hookup, and final inspection
We work directly with general contractors and owner-builders on the island. If you’re in the planning phase of a new Bainbridge Island build, we’re available to review plans, provide a scope estimate, and get on your schedule early — which matters on an island where contractor availability moves fast.
