When Should You Hire a Plumber for a New Construction Home in Louisiana?
If you're building a new home or commercial property, plumbing may not be the first thing you think about. But long before you choose faucets or decide between a traditional and tankless water heater, important plumbing decisions need to be made.
Much of a building's plumbing system is eventually hidden beneath the concrete slab, inside walls, and above ceilings. Waiting too long to involve a plumber can make changes more complicated once construction is underway.
So, when should you hire a plumber for new construction?
Ideally, you should involve your plumber early in the planning and construction process, before underground plumbing is installed and before the foundation is poured.
Here's how plumbing typically fits into a new construction project and why each stage matters.
Why Involve a Plumber Early in a New Build?
New construction plumbing isn't simply a matter of installing sinks and toilets after the house is built.
Your plumber needs to plan for water supply lines, drain and waste lines, vents, sewer connections, water heaters, gas lines when applicable, and the plumbing connections required for every fixture and water-using appliance.
Those plans also have to coordinate with the home's layout and the work being performed by other trades.
Getting a plumber involved early gives the plumbing team an opportunity to review the project before important components become inaccessible.
Stage 1: Planning the Plumbing Layout
Plumbing begins before pipes are installed.
The plumber needs to understand where kitchens, bathrooms, laundry rooms, water heaters, and other plumbing fixtures will be located.
This is also a good time for homeowners and builders to think about features such as:
Number and location of bathrooms
Kitchen and island plumbing
Outdoor faucets
Laundry connections
Traditional versus tankless water heaters
Gas appliances
Additional sinks or wet bars
Refrigerator and ice maker connections
Utility or garage sinks
Outdoor kitchens
Future plumbing needs
Making these decisions early can reduce the need for changes later in construction.
Stage 2: Underground and Under-Slab Plumbing
For homes built on concrete slabs, some of the most important plumbing work happens before the slab is poured.
Depending on the building design, plumbing lines may need to be positioned beneath or within the future slab. Once concrete covers these areas, making changes becomes significantly more involved.
That's why accurate placement during this stage is so important.
Your plumber will coordinate the necessary underground plumbing based on the construction plans and intended locations of bathrooms, kitchens, and other fixtures.
For homeowners building in Greater New Orleans or on the Northshore, this is one reason to select your plumbing contractor well before you reach the finishing stages of the home. Learn more about our under slab plumbing services.
Stage 3: Plumbing Rough-In
Once framing is underway, the project reaches another major plumbing stage: the rough-in.
A plumbing rough-in generally involves installing the piping and connections that will eventually serve the building's fixtures and appliances.
You may see water lines running through wall framing and drain and vent piping positioned where sinks, toilets, showers, tubs, and appliances will eventually be installed.
At this point, the house may not look anywhere close to finished, but much of the infrastructure necessary for the finished plumbing system is taking shape.
What Happens During a Plumbing Rough-In?
The exact work depends on the building, but rough-in plumbing may involve:
Water supply piping
Drain and waste piping
Vent piping
Shower and bathtub connections
Toilet plumbing
Sink plumbing
Kitchen connections
Laundry connections
Water heater connections
Gas piping when applicable
Once walls are closed, many of these components will no longer be visible. This makes the rough-in stage particularly important.
Stage 4: Water Heater and Gas Line Planning
A new construction project also gives you the opportunity to decide what type of water heating system makes sense for the property.
Homeowners may choose between a traditional tank-style water heater and a tankless system.
If the property will use gas for the water heater, range, dryer, outdoor kitchen, or other appliances, gas line requirements should also be incorporated into the construction plans.
These decisions shouldn't be left until the last minute because the appropriate connections need to be planned as part of the overall plumbing system. Leanr more about our water heater installation services, including tankless water heater installs.
Stage 5: Installing the Finished Plumbing Fixtures
Once drywall, cabinetry, countertops, flooring, and other finishes are installed, the plumber can return for the fixtures and final plumbing connections.
This is when the plumbing system finally begins to look familiar to the homeowner.
Depending on the project, the plumber may install and connect:
Toilets
Bathroom sinks
Faucets
Kitchen sinks
Garbage disposals
Showers
Bathtubs
Dishwashers
Refrigerators and ice makers
Washing machines
Water heaters
Other plumbing fixtures and appliances
Because the necessary plumbing was planned and installed earlier, the appropriate water and drainage connections should already be positioned for these fixtures. Leanr more about our kitchen and bathroom plumbing services.
Stage 6: Final Connections and Testing
Before construction is complete, plumbing connections need to be finished and the system checked.
The plumber can verify that fixtures and equipment are properly connected and identify issues that need to be addressed before the project is finished.
This is another reason it can be helpful to work with the same plumbing company throughout the construction process. The plumber is familiar with the system that was installed during the earlier stages of the build.
Should You Hire a Plumber Before Your General Contractor Starts Construction?
You don't necessarily need to independently hire a plumber before selecting your builder or general contractor. However, the plumbing contractor should become involved early enough to coordinate with the project's construction schedule.
Builders and general contractors often work directly with plumbing contractors to determine when underground work, rough-ins, and final installations need to occur.
If you're acting as your own general contractor or building a custom home, it's particularly important to make sure you have a plumber lined up before construction reaches a stage where plumbing work is required.
What Should You Ask a New Construction Plumber?
Before choosing a plumber for your project, ask questions about their experience and how they'll coordinate with the rest of the construction team.
Good questions include:
Do you handle complete new construction plumbing?
Do you work on both residential and commercial projects?
Can you handle underground and rough-in plumbing?
Do you install traditional and tankless water heaters?
Do you provide gas line installation?
Will you return for final fixture installation?
What information or plans do you need before beginning?
How will you coordinate scheduling with the builder or general contractor?
What areas do you serve?
The goal is to understand whether the plumber can handle the project from the early plumbing stages through completion.
Residential and Commercial New Construction Plumbing
The basic stages of plumbing apply to both residential and commercial construction, but the size and complexity of the systems can vary considerably.
A custom home may require several bathrooms, a large kitchen, outdoor plumbing, multiple water heaters, or specialty fixtures.
Commercial buildings may have more extensive plumbing requirements depending on the property's size and intended use.
In either situation, planning the plumbing alongside the rest of the construction project helps keep the work coordinated from beginning to end.
