New Construction Plumbing in Montana City, MT
Plan the pipes before the walls close. We install water, drain and vent lines in the right order, then return to connect the fixtures.
Plumbing that fits the build schedule
A new home leaves one chance to place plumbing where it belongs. Montana City homeowners and builders hire A+ 406 Waterworks to install supply, drain, vent and fixture lines as the project moves along, working from your layout so kitchens, baths, laundry and utility rooms get what each one needs.
We drive out from Helena for each stage, and we check line placement before an area is closed in. That is far easier than reopening a wall later.
The complete service is described on our New Construction Plumbing page, and every quote is free.

How a Montana City build goes with us
Plumbing touches the job at several points. Each visit has a clear purpose.
- 01
Read the plan
We match pipe routes, shutoff access, drainage and venting to the approved layout before work moves far.
- 02
Rough-in
Hidden water, drain and vent lines go in ahead of wall and floor finishes, set around framing, cabinets, tubs and showers.
- 03
Check before closing
While piping is still open, testing can catch leaks or bad connections that finished walls would hide.
- 04
Final connections
When surfaces are ready, we return to connect sinks, toilets, faucets and equipment, then check the visible connections.
Less rework between trades
Layout checks
A misplaced toilet or shower drain is costly once cabinets arrive. We compare plumbing locations with the room plan early.
Clear scheduling
We tell you when our stage can start and what must be done first, so no trade sits waiting.
Fixture readiness
Fixtures get connected when the area is prepared, which keeps them clear of other trades and out of storage limbo.
Thinking about a basement bath or a wet bar later? Mention it now. Drain, vent and supply access is simpler to plan before floors are finished.

Montana City new construction FAQ
What if I decide to add a basement bathroom later?
Raise it before the slab or finished floor is done. Future drain, vent and water connections are easier to plan during construction, and a plumber can review the proposed spot and explain what preparation makes sense.
Can I change a sink or toilet location after rough-in?
Often yes, but the difficulty depends on how far the build has progressed. Moving lines after concrete, drywall, cabinets or flooring are in can mean extra work, so bring layout changes to your plumber early.
Should I plan plumbing for a future wet bar?
If a wet bar is a real possibility, plan supply and drain access during construction. It can cut down how much finished material has to be opened later. Review the location before rough-in.
What happens if my fixture choice changes during construction?
Tell your plumber before final connections are prepared. Sinks, tubs, toilets and faucets can have different connection needs, so early notice lets the team check that the rough-in matches the new fixture.
Do new plumbing lines need testing before walls close?
Testing while piping is accessible can reveal leaks or connection problems before finishes limit access. Rough-in is normally done before walls close, which makes that stage the right time to check the system.
I am building my first home. When should I contact a plumber?
Contact one while plans and room layouts are still being finalized. Early involvement shows plumbing needs before construction narrows your routing options. A+ 406 Waterworks can discuss your planned build and layout.
