New Construction in Bath, ME
Complete rough-in and trim-out for new homes and additions across Central Maine — on schedule and to code.
New Construction for Bath Homeowners
Bath sits within the territory RJC Plumbing covers out of Augusta every week — so a call for new construction gets a plumber who already knows the local housing and permit process, not a first-timer.
RJC Plumbing provides complete plumbing system installations for new construction projects across Central Maine, coordinating with builders to ensure every pipe, fixture, and connection is installed right the first time.
What does our new construction plumbing include?
We install the full plumbing system for new homes, additions and garage apartments: underground drain and water lines, above-ground drain, waste and vent piping, supply lines, the water heater, and fixture trim-out.
We also plumb for hydronic heat — boilers and baseboard — when the job calls for it, and set well pressure tanks and water treatment on homes outside municipal water. One trade, one point of contact for the builder.
Our customers include general contractors building in Augusta, Manchester, Winthrop and the surrounding towns, and owner-builders who need a plumber that returns calls and shows up on the day promised.
How does the new construction process work?
Underground: after the foundation is in and before the slab, we set the below-grade drain lines, cleanouts and water service entry. Photos are taken before backfill.
Rough-in: once the frame is up, we run supply and drain-waste-vent lines, stub out every fixture location, set tub and shower units, and pressure-test for inspection.
Trim-out: after drywall, paint and cabinets, we return to set toilets, faucets, sinks, the water heater and any remaining fixtures, then test every connection.
Why do venting and pipe sizing matter?
Undersized drains and missing vents are behind most "the new house already has plumbing problems" calls. We size lines by fixture units and lay out venting so every trap holds its seal.
Maine winters also decide where lines can run. We keep supply piping out of exterior walls and unheated spaces, and insulate where a line has no other route.
Working with builders and homeowners
We review the plans early, flag conflicts with framing or HVAC before they are built, and keep to the schedule so the next trade is not waiting on us.
For owner-builders we walk you through fixture selection and rough-in dimensions so what you order fits what we installed.
Why Bath Chooses RJC Plumbing
- Close enough to Bath for a fast response, local enough to know the town
- A written, upfront price — no surprises on the invoice
- Urgent calls do not wait behind routine ones on our schedule
- Licensed, insured, and background-checked — call and you will reach a real person, not a call center
Bath's Homes and Plumbing
Exterior work on a building inside the Bath Historic District needs Planning Board review, though the city says it is often completed administratively in as little as three days. That review is about the outside of the house, not what happens behind the walls, so it rarely slows down a bathroom or kitchen plumbing job.
The Bath Water District has supplied the city from Nequasset Lake in neighboring Woolwich for more than a century. Wastewater is handled by the city’s own Public Works department, whose treatment plant averages about 2 million gallons a day across 13 pump stations, discharging to the tidal Kennebec. Part of Bath’s sewer system uses combined sewers that can overflow in heavy rain, which is one reason the city cares about keeping stormwater and groundwater out of the sanitary side.
Family-Owned, Not a Franchise
RJC Plumbing has been a family-owned, Augusta-based business since 2022, and Bath has been part of our territory the whole time. The estimate is free, the price is upfront, and there are no hidden fees added after the fact. We would rather earn the next call than upsell this one.

Codes & Permits for New Construction in Bath
In Bath, plumbing permits come from the Local Plumbing Inspector at the City of Bath Code Enforcement Office (55 Front St., Bath, ME 04530, (207) 443-8330). With 8,815 residents, Bath is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Part of the City's sewer system uses combined sewers that can overflow during heavy rain, prompting ongoing infrastructure upgrades (e.g., the Harward Street sewer/pump station project).
- Buried water service lines and other freeze-sensitive plumbing in new construction are expected to go in below the local frost line under the International Residential Code provisions Maine adopted via MUBEC (2021 IRC, effective April 7, 2025); the exact burial depth follows local frost-depth practice rather than one statewide number. www11.maine.gov
- New-construction plumbing in Maine towns is inspected in at least two stages under the local code office's process: a rough-in inspection before walls are closed in during framing, and a final/occupancy inspection once fixtures are connected. townofnaples.org
- The Maine Plumbers' Examining Board (within the Office of Professional and Occupational Regulation, Department of Professional and Financial Regulation) licenses plumbers statewide and maintains the plumbing rules and laws (Title 32, Chapter 49); day-to-day permit issuance and inspection for a given town is carried out locally by a Local Plumbing Inspector (LPI), who is often the same person as the municipality's Code Enforcement Officer. maine.gov
How RJC Plumbing Handles New Construction in Bath
- We rough in supply and drain lines to pass Bath's framing-stage inspection, then come back for the final once fixtures are set — the two-stage process most Maine code offices run.
- Buried water service gets set below the local frost line, per the 2021 residential code Maine adopted for new construction — we build to local frost-depth practice, not a guess.
- With 8,815 residents, Bath is over the line at which Maine requires a town to enforce the statewide building and energy code, so new-construction plumbing here is inspected against that code alongside the plumbing rules.
- Scheduling both inspections with City of Bath Code Enforcement Office is on us — you get a straight answer on when the next stage of a new construction job can move.

New Construction Questions from Bath Homeowners
Do you work with general contractors or directly with homeowners?
Both. Most of our new-construction work comes through builders, but we also work directly with owner-builders and homeowners managing an addition.
Can you quote from a set of plans?
Yes. Send the plans and fixture schedule and we will return a written quote covering underground, rough-in and trim-out, with allowances noted where fixtures are not yet selected.
Do you handle the plumbing inspections?
We schedule and are present for the rough-in and final plumbing inspections required by the town, and we correct anything the inspector flags.
Do you install boilers and radiant or baseboard heat?
Yes. We install boilers, hydronic baseboard and the piping for radiant systems as part of a new build or addition.
What about homes on a well?
We set the pressure tank, pressure switch and any water treatment equipment and tie the well line into the house. Well drilling itself is done by a well driller.
How far in advance should we book?
Call once you have a foundation date. Underground and rough-in have to fit between other trades, and a few weeks of notice keeps your build on schedule.
