Plumbing for Remodels & Home Additions in Hillsboro

When You Need Remodel Plumbing Service

Any time you are changing the layout of a kitchen or bathroom, whether moving a sink to a different wall, relocating a toilet, adding a shower where there was only a tub, or converting a half bath to a full bath, you need professional plumbing work. Adding a bathroom to a basement, converting a garage to living space with plumbing, building an ADU (accessory dwelling unit) on your property, or adding a laundry room all require new plumbing rough-in from scratch. Kitchen remodels that move the sink to an island or different wall location require drain and supply line rerouting. Even cosmetic remodels that keep fixtures in the same location often reveal corroded valves, deteriorated supply lines, or drain connections that should be upgraded while the walls are open. If your remodel involves opening walls or removing flooring, it is the ideal time to address any aging plumbing behind those surfaces.

What Remodel Plumbing Service Looks Like

Remodel plumbing happens in phases that align with the construction timeline. The first phase is planning. We review your remodel plans, identify where new plumbing needs to run, determine if existing drain and vent lines can support the new layout, and flag any code requirements that affect the design. The second phase is rough-in, which happens after demolition and framing but before drywall. We install all new supply lines, drain lines, and vent pipes in the wall and floor cavities. Supply lines are run to each fixture location with stub-outs capped for pressure testing. Drain lines are installed at proper slope with connections to the existing drain system. Vent lines are routed to tie into existing vents or through the roof for new vent stacks. The rough-in is inspected before walls are closed. The third phase is trim-out. After drywall, tile, and finish work are complete, we return to install fixtures: toilets, sinks, faucets, shower valves, tub fillers, and all final connections. We test everything for proper operation and leak-free performance.

How Long Remodel Plumbing Takes

Timelines depend entirely on scope. A bathroom remodel keeping fixtures in the same locations, just upgrading the toilet, vanity, and shower valve, requires 1 day for rough-in modifications and half a day for trim-out. A bathroom remodel relocating fixtures to new positions requires 1 to 2 days for rough-in and a full day for trim-out. A full kitchen remodel with island sink relocation requires 1 to 2 days for rough-in. Adding a complete new bathroom to a space without existing plumbing requires 2 to 3 days for rough-in. ADU plumbing with full kitchen and bathroom requires 3 to 5 days for rough-in depending on size and complexity. We schedule our phases to align with your contractor's timeline so plumbing never holds up the project.

What Remodel Plumbing Typically Costs

Remodel plumbing costs scale with complexity. A simple fixture-in-place bathroom upgrade with new valves and connections costs significantly less than a full layout change requiring new drain routing. Factors that affect cost include: number of fixtures being added or relocated, distance from existing drain and vent connections, whether new vent stacks are required, floor type (wood subfloor vs. concrete slab), and accessibility of the space below for drain routing. Kitchen island sinks require special venting solutions that add cost. ADU plumbing is priced as a complete system including water heater, all fixtures, and connection to the main house supply and sewer. We provide detailed estimates broken down by phase so you can budget accurately.

Local and Seasonal Factors in Hillsboro

Hillsboro is experiencing significant residential growth and renovation activity. Older homes in established neighborhoods are being remodeled to modern standards, while new ADU construction is increasingly common as Oregon's ADU-friendly regulations encourage homeowners to add rental units or family living space. Many homes built in the 1970s through 1990s have original plumbing that should be upgraded when walls are opened during remodels. This is the most cost-effective time to replace aging supply lines, corroded valves, and deteriorating drain connections. The Portland metro area's building permit process requires plumbing inspections at rough-in stage, which means professional installation that meets code is not optional. Homes with crawl space access have easier drain routing for additions compared to slab-on-grade homes that require in-wall or overhead drain routing. We work with both scenarios regularly across Hillsboro, Beaverton, and surrounding communities.
