Inspection-Ready New Construction Plumbing Services in Marietta, GA

Gas Piping for New Homes in Marietta

We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens. Black iron and CSST systems are both options, and CSST is bonded per manufacturer and code requirements. We calculate total BTU load and pipe length so every appliance gets enough pressure even when everything runs at once. The system is pressure tested and inspected before the utility sets the meter.

Underground and Under-Slab Plumbing in Marietta

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. Much of Georgia sits on dense red clay that swells when wet and shrinks in drought, which can stress slab plumbing and sewer laterals over time. 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.

Rough-In and Top-Out Plumbing in Marietta, GA

Once framing is up, we run supply and vent lines through the walls and attic and set every stub-out for sinks, tubs, showers and appliances. We typically install PEX-A with a central manifold so each fixture gets its own line and shutoff. Shower valves are set at the heights you choose, and tub sets are installed and protected before the drywall is hung. A full pressure test is held for inspection so nothing hidden in the walls is ever in doubt.

New Construction Plumbing Cost Planning in Marietta, GA

Plumbing for a typical new single-family home often 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 move the number most. We break the bid out by phase so you can see clearly where the money goes.

Preventing Common Georgia Plumbing Issues in New Builds in Marietta, GA

New construction in Georgia must account for local conditions. Much of Georgia sits on dense red clay that swells when wet and shrinks in drought, which can stress slab plumbing and sewer laterals over time. We focus on installations that hold up to shifting foundations and soil movement, which can stress pipes. Homes farther south often draw from deep limestone aquifers, so harder water and the occasional sulfur smell are common complaints there. We recommend suitable piping materials and treatment options to minimize scale buildup over time, so your new home's plumbing lasts for decades.

Fixture Installation and Finishing in Marietta, GA

Once the rough-in is complete and walls are up, HGR Plumbing handles the final installation of all plumbing fixtures. This includes sinks, toilets, showers, bathtubs, dishwashers, and washing machines. We ensure everything is perfectly aligned, sealed, and fully functional, providing a polished finish to your new home's plumbing system.

Water Heater and Recirculation Installation in Marietta, GA

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 far cheaper than retrofitting later. Homes farther south often draw from deep limestone aquifers, so harder water and the occasional sulfur smell are common complaints there. If treatment makes sense for your water, we recommend planning space for a softener or filter loop at the same time.
