Inspection-Ready New Construction Plumbing Services in South Portland, ME

Water Heater and Recirculation Installation in South Portland, ME

New homes commonly use tank water heaters in the garage, basement or utility room, or tankless units on an exterior wall. We size the heater to your bathroom count and install gas or electric connections, venting, an expansion tank and drain pan where required. Many owners add a dedicated recirculation line during rough-in, which is much less expensive than retrofitting later. Municipal water in Maine is generally soft, but soft, slightly acidic water can slowly corrode copper pipes and cause pinhole leaks. If treatment makes sense for your water, we recommend planning space for a softener or filter loop at the same time.

New Construction Plumbing Cost Planning in South Portland, ME

Plumbing for a typical new single-family home usually runs about 4 to 8 percent of total build cost, depending on fixture count and finish level. A modest three-bedroom home often lands between $12,000 and $25,000, while custom homes with multiple suites and outdoor kitchens run higher. Choices like a manifold PEX system, a recirculation loop and fixture grade affect the price the most. We break the bid out by phase so you can see exactly where the money goes.

Underground and Under-Slab Plumbing in South Portland

The underground phase sets the drain, waste and vent layout that every fixture in the house will rely on. We trench, bed and slope PVC or ABS drain lines at a minimum quarter inch per foot and protect every pipe that passes through the slab or foundation with sleeves. Basements are standard in most Maine homes, and groundwater and snowmelt make sump pumps and drainage important. We compact bedding carefully and avoid rigid points that could stress the pipe as the ground moves. Each line is water tested and left exposed for the inspector before your concrete contractor pours.

Commercial New Construction Plumbing in South Portland, ME

We offer comprehensive commercial new construction plumbing for businesses, multi-family units, and industrial properties. This includes larger capacity water heaters, backflow prevention devices, specialized drainage systems, and compliance with commercial building codes. Our team handles everything from large grease traps for restaurants to long piping networks for office buildings, ensuring solid and efficient plumbing infrastructure across South Portland.

Fixture Installation and Trim-Out in South Portland, ME

Once the rough-in is complete and walls are up, our team returns for fixture installation and trim-out. This includes connecting sinks, toilets, bathtubs, showers, dishwashers, and water heaters. We ensure all fixtures are properly seated, sealed, and functional, providing a clean finish to your new construction plumbing. We work with many brands like Moen, Kohler, and American Standard to match your design specifications.

Final Trim and Fixture Setting in South Portland

At trim we install toilets, faucets, garbage disposals, dishwashers, ice maker boxes and laundry connections. We work with fixtures from Moen, Delta, Kohler, American Standard and the other brands builders commonly specify, or with owner-supplied fixtures. Every fixture is checked for flow, drainage and leaks, and angle stops are set straight and tight. We finish by running every fixture at once to confirm the system drains and vents properly under load.
