A general contractor can manage a bathroom renovation, but the plumbing work itself should be done by a licensed plumber. In New Mexico, plumbing and gas work require licensing for a reason — and permitted, inspected plumbing is what protects you when you sell the house or file a claim.
What the Plumbing Portion Actually Involves
- Rough-in. Relocating supply and drain lines to new fixture positions, which is where most renovation plumbing errors happen.
- Venting. Every fixture needs proper venting or its trap siphons dry and lets sewer gas into the room. Moving a fixture without addressing the vent is the single most common renovation mistake we get called to fix.
- Drain slope. Too little and water sits; too much and solids outrun the liquid. Both cause chronic problems.
- Shower pan and drain sealing, where a mistake shows up months later as a stained ceiling below.
- Fixture and valve installation, including pressure-balancing shower valves required by code.
- Material transitions where new pipe meets existing cast iron or galvanized.
Why It Matters Beyond Code
Renovation plumbing gets buried behind tile and drywall. An error is invisible until water damage reveals it, and by then the finish work has to come back out. This is the phase where paying for expertise is cheapest.
How It Usually Works
Your general contractor coordinates the trades and we handle the plumbing scope — often working directly with the GC on schedule and rough-in timing. Homeowners acting as their own GC can hire us the same way.
Worth Addressing During the Renovation
Walls are open, which makes this the cheapest time to replace corroded angle stops and supply lines, upgrade aging galvanized pipe serving the bathroom, add a pressure reducing valve if house pressure is high, or handle a partial repipe. Doing it later means opening new tile.
Permits
Bathroom plumbing changes typically require permits and inspection. We pull them — unpermitted work surfaces at the worst time.
