New Construction in Lisbon, ME

Complete rough-in and trim-out for new homes and additions across Central Maine — on schedule and to code.

New Construction for Lisbon Homeowners

For new construction in Lisbon, homeowners turn to RJC Plumbing: a family-owned, Augusta-based crew that already knows the area's homes, water and sewer setups, and how the local code office works.

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 Lisbon Chooses RJC Plumbing

  • Based a short drive from Lisbon and out on Central Maine calls every day
  • A written, upfront price — no surprises on the invoice
  • Most urgent calls get worked into the schedule the same day
  • A fully licensed and insured Master Plumber — call and you will reach a real person, not a call center

Lisbon's Homes and Plumbing

About 69% of Lisbon homes heat primarily with oil, one of the higher shares among the towns we serve, with propane a distant second and no confirmed natural gas utility in town. A replacement water heater here is typically a tank, tankless or hybrid heat-pump unit, and our water heater installation team will size it to your household’s hot water use.

Lisbon is one of the few towns on our list that names its Electrical Inspector directly on the town website, alongside its Code Enforcement office at 300 Lisbon Street, which handles plumbing permits under the state’s Internal Plumbing Code. Every job, including new construction plumbing and emergency repairs, starts with a free estimate and an upfront price. See all of our service areas.

Family-Owned, Not a Franchise

RJC Plumbing is a family-owned company based in Augusta, serving Lisbon since 2022. Being small means fewer layers between you and the person actually doing the work. We show up, fix the actual problem, and let the work speak for itself.

Codes & Permits for New Construction in Lisbon

In Lisbon, plumbing permits come from the Local Plumbing Inspector at the Code Enforcement, Town of Lisbon (Lisbon Town Offices, 300 Lisbon Street, Lisbon, ME 04250, 207-353-3000 ext. 108). With 9,711 residents, Lisbon is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The town's sewer system is run directly by Lisbon's own Public Works department rather than a separate regional district, per the town's sewer rate/ordinance pages.

  • 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 Lisbon

  • A new construction job here goes through the same two stops most Maine towns require: a rough-in inspection before the walls close up, then a final once every fixture is connected.
  • Any water line we bury on a new construction job goes below frost depth as the state's 2021 residential code requires, following what Lisbon's own code office treats as local frost-depth practice.
  • With 9,711 residents, Lisbon 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 Code Enforcement, Town of Lisbon is on us — you get a straight answer on when the next stage of a new construction job can move.

New Construction Questions from Lisbon 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.
