Concord
Concord homes, remodeled right
In Concord, remodel plumbing meets the housing stock head-on. Steep roofs with thin attic insulation make ice dams endemic. 18th- and 19th-century colonials, Victorians, and capes with full basements. 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 Merrimack County, renovators learn the same lesson: steep roofs with thin attic insulation make ice dams endemic.. Aging pipe stock: Concord's older homes still run galvanized and cast-iron systems that corrode from the inside and fail with little warning. A local pro anticipates what the walls will reveal.

When to bring in the pro
The rule is simple: anything behind the wall or under the floor is pro work. Here is the checklist.
- 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 remodel plumbing includes
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.
Planning steps
Finalize the layout before the first pipe is cut — moving drains after rough-in is where budgets die. Do this first.
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.
How remodel plumbing works
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.
The decision factors
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.
