What's included

From plan markup to final inspection.

A new build is the only chance you get to put plumbing exactly where it should be. Wrong dimensions on a closet bend, a poorly vented branch line, a tub that doesn't fit because the framer guessed — those mistakes are 10x harder to fix after drywall. Kiley starts at the plan stage, marks up the architectural drawings with our rough-in dimensions, and ensures everything ties together before the framers leave.

We handle the full plumbing scope on a custom home: building drain in or under-slab, complete DWV with proper venting and cleanouts, supply lines (PEX manifold or copper, per your spec), gas service distribution, water heater install, plumbed-in radiant heat loops, and finish-set on every fixture from kitchen sink to powder room.

We coordinate with your GC, electrician, HVAC, and well/septic contractors. Permits and inspections in your town are pulled, documented, and signed off — you get a clean folder for closing.

Plan, rough-in, finish.

Step 01

Plan markup

We review architectural drawings, mark fixtures, and identify any issues with the layout before framing.

Step 02

Underground & rough

Building drain, DWV, supply, gas. Pressure-test before backfill or drywall. Inspector signs off rough.

Step 03

Top-out & finish

Once cabinets and tile are set, we install fixtures, water heater, and connect appliances.

Step 04

Final & closeout

Final inspection, documentation, walkthrough with the homeowner, signed-off permit folder.

FAQ

New construction FAQ.

Do you work as a sub for custom-home builders?
Yes. We're a regular plumbing sub for several Metrowest custom-home builders. We coordinate on schedule, plan markup, and inspection windows.
Can you handle the full DWV and supply rough-in?
Yes. We rough in supply (PEX or copper depending on your spec), drain-waste-vent, gas, and plumbed-in radiant. We mark fixtures from your plan and adjust on-site as framing dictates.
Do you handle septic system tie-in?
We handle the building drain to the foundation. Beyond that, septic install is typically by a Title 5 contractor; we coordinate on tie-in elevation and venting so your inspector signs off the first time.
Will my new build need a separate permit for plumbing?
Yes. New construction in Massachusetts requires distinct plumbing and gas permits separate from the building permit. We pull both, schedule rough and final inspections, and document everything for your closing.
