Hillsboro
Hillsboro homes, remodeled right
In Hillsboro, remodel plumbing meets the housing stock head-on. Downtown's historic homes carry aging plumbing through decades of wet seasons. New South Hillsboro developments are still proving their grading and drainage. Opening walls in older homes reveals the plumbing eras — and the pro's job is bringing all of it up to the same standard.
Around Washington County County, renovators learn the same lesson: downtown's historic homes carry aging plumbing through decades of wet seasons.. Freeze snaps: Oregon winters are mostly mild but hard freezes still burst attic runs and exterior-wall plumbing every few years. A local pro anticipates what the walls will reveal.

Remodel plumbing triggers
If the remodel touches water, drains, or gas, it touches a plumber. These are the moments Hillsboro renovators call one in.
- You are moving any fixture — toilet, sink, tub, or shower — from its current location.
- Converting a tub to a shower or adding a second sink.
- Galvanized or polybutylene supply lines exposed during demolition.
- An older home where the existing plumbing predates current code.
- Adding a bathroom or wet bar where no plumbing exists yet.
What the pro does on a remodel
The invisible work determines whether the visible work lasts. Expect the pro to cover both.
- Rough-in plumbing: supply and drain lines run to the new fixture locations.
- Drain, waste, and vent layout verified for proper slope and venting.
- Fixture installation: toilets, sinks, faucets, showers, tubs, and dishwashers.
- Gas line work for relocated ranges, dryers, or fire features, where needed.
- Coordination with your general contractor on sequencing and inspections.
- Final trim-out, leak checks, and pressure testing before handoff.
Before the walls open
The cheapest plumbing change is the one made on paper. These planning steps save real money.
Safe to do now
- Finalize your fixture layout before the plumber starts — changes mid-rough-in are expensive.
- Choose and purchase fixtures early so rough-in dimensions match.
- Photograph the open walls showing new pipe runs before drywall goes up.
- Keep a clear path and workspace for the plumbing crew during rough-in.
Stop — call a pro
- Do not close walls before the plumbing rough-in is inspected.
- Moving drain lines yourself — slope and venting rules are unforgiving.
- Setting a toilet or connecting a shower valve without checking the rough-in dimensions.
- Skipping permits on plumbing changes — it complicates future sales and insurance.
From plans to finished bath
Rough-in, inspection, close-up, trim-out: the rhythm of the job. The phases explained.
Plan review: the pro reviews your layout and flags what the plumbing will require — moves, venting, and code upgrades.
Rough-in: new drain, supply, and vent lines are run and left ready for inspection before walls close.
Inspection: the rough-in is pressure-tested and inspected per local code.
Finish: after walls and tile, fixtures get set, connected, sealed, and tested.
What affects remodel plumbing cost
Moving fixtures costs far more than replacing them in place — distance is money. These factors set the budget.
- How far fixtures move — across the room costs far more than a like-for-like swap.
- Whether drain lines need rerouting under a slab versus through accessible framing.
- Bringing old work up to current code — venting, shutoffs, and anti-scald valves.
- Fixture count and complexity — body sprays, pot fillers, and double vanities add rough-in work.
- Permit and inspection fees for the plumbing scope.
