New Construction Plumbing in Goodlettsville
We plumb new houses and room additions, starting with drain lines under the slab and finishing with fixtures on the counters. First we read your plans and walk the lot, so a bad drain route or tight vent gets fixed on paper before concrete covers it.
Plumbing a New Home the Right Way the First Time
New construction plumbing covers the water, drain and vent piping in a house going up, along with the gas lines and fixtures that connect to it. Most of that pipe ends up buried in concrete or hidden behind walls. After drywall, fixing a mistake gets costly.
So we begin with the drawings. We check where each fixture lands, how drains will fall, where vents can go and how water comes in from the meter. If a toilet sits on top of a joist or a drain has no room for slope, we point it out before framing starts.
We hold a Tennessee CMC-A plumbing license, and every pipe we put in your build goes in under it. We're licensed and insured, too. Builders, general contractors and people putting up their own home call us in Goodlettsville and nearby towns like Millersville, Hendersonville and White House.
What the Work Includes
- Plan review and layout
- We mark each fixture, drain route and vent path on the drawings. You get a short list of anything that should change before work begins.
- Underground rough-in
- Drain and waste lines go in at the correct slope under the slab or in the crawlspace. We test them before the pour or backfill, because this is the stage that is hardest to redo.
- Top-out in the walls
- Once the house is dried in, supply lines, drains and vents run through the framing. When the layout gives us a choice, water pipe goes in an inside wall. Pipe sitting behind siding is the first to freeze on a hard winter night.
- Water service and backflow
- We bring the line from the meter into the house and put the main shutoff where you can get to it. We are backflow certified, so an irrigation system or other connection that calls for a backflow preventer gets one installed by us.
- Water heater and fixture set
- After paint and flooring are done, we set toilets, sinks, tubs and faucets and hook up the water heater. Going tankless is easier when the gas sizing and vent route are worked out back at rough-in; our Tankless Water Heater Installation page explains more.
When to Bring in a Plumber on Your Build
Your plans are done but not checked
The architect drew where fixtures go, not how pipe gets there. A plumbing review now costs far less than a change after framing.
The slab pour is on the calendar
Underground plumbing has to be in, tested and inspected before concrete. If your pour date is set, the plumber needs to be lined up now.
You're building an addition
A new bathroom or kitchen on an existing house has to tie into drains and supply lines that were sized for less. We check what's there before adding to it.
Your last plumber fell through
Builds stall when a sub stops showing up. We can pick up a job mid-stream, but first we look at and test what's already in so we know what we're inheriting.
What Sets the Price
No two builds are alike, so we price from your drawings instead of a per-square-foot guess. The number comes split into rough-in, top-out and trim, and each line shows what it covers. If paying over time helps your budget, ask us about financing. Cash and all major credit cards work too.
Number of fixtures
Every bathroom, sink, hose bib and laundry hookup adds pipe, fittings and labor. Fixture count moves the cost more than square footage does.
Foundation type
On a slab, every drain has to be in before the pour. A crawlspace or basement leaves more working room and changes how the lines are routed.
Pipe and equipment choices
PEX and copper differ in both material and labor cost. A tankless water heater or a filtration system adds gas, venting or space planning.
Distance to the meter
A long trench from the street, or one that runs into rock or under a driveway, takes more digging time.
Changes mid-build
Moving a tub after top-out means tearing into finished work. Locking in the layout early keeps the cost close to where it started.
How a New Construction Job Runs
- 1
Estimate and plan walk
We go over your drawings and the lot, then put the price in writing, split into rough-in, top-out and trim. There is no charge for the estimate.
- 2
Permit and rough-in
We pull the plumbing permit and lay the underground lines. Each line gets a pressure or water test, and the inspection is booked before anything is covered.
- 3
Top-out and second inspection
With framing up and the roof on, we run pipe through the walls and test it again. The inspector signs off before insulation and drywall go in.
- 4
Trim, final and walkthrough
We set the fixtures and water heater, turn the water on and check every joint for drips and pressure. Then we show you where the shutoffs are and get the final inspection passed.
New Construction Plumbing Questions
Do you work with owner-builders or only general contractors?
Both. If you're building your own home, we'll talk you through when we need to be on site and what has to be ready before each stage. We coordinate the inspections either way.
Do you handle the permit and inspections?
Yes. We pull the plumbing permit and schedule each inspection at rough-in, top-out and final. We test our own work before the inspector comes, so it passes on the first visit.
Should I use PEX or copper?
Most new homes here get PEX. It costs less, has fewer joints in the wall and handles a freeze better than copper. Copper still makes sense in some spots, and we'll tell you where during the plan review.
Can I add a whole home filtration system later?
You can, but it's easier to plan for now. We can leave a spot and the right fittings near where the water line enters, so a system from our Whole Home Water Filtration service drops in without cutting into finished walls.
What if something goes wrong on site after hours?
We offer 24/7 emergency plumbing service. If a line gets hit during grading or a fitting lets go after the water is on, call and we'll come out.
