Our trained technicians install new gas lines for appliances like furnaces, water heaters, stoves, and outdoor grills. We use approved materials and conduct rigorous leak testing to ensure the safety and integrity of your gas system, meeting all Georgia and local Alpharetta codes.
Water Heater Installation for New Builds in Alpharetta
Selecting and installing the right water heater is essential for any new construction. We provide expert installation of traditional tank-style and tankless water heaters, considering your property's hot water demands and energy efficiency goals. Our plumbers confirm correct sizing, venting, and gas or electrical connections, adhering to all safety regulations for new homes in Alpharetta.
Sewer and Drainage Systems in New Builds in Alpharetta
A dependable sewer and drainage system is essential for any new property. We design and install complete sewer lines, septic systems, and storm drains, making sure of proper grading and connection to municipal services or on-site treatment systems. 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 account for soil movement on your lot, using tough PVC piping and careful bedding to prevent future blockages or pipe damage.
Gas Line Installation for New Homes in Alpharetta
If your new home will use natural gas for heating, cooking, or water heating, HGR Plumbing provides safe and code-compliant gas line installation. This involves running new gas lines from the main supply to all gas equipment. Our licensed plumbers confirm all connections are secure and tested for leaks, adhering to strict safety protocols for gas work.
Rough-In and Top-Out Plumbing in Alpharetta, 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 goes on. A full pressure test is held for inspection so nothing hidden in the walls is ever in doubt.
Permits and Inspections for New Plumbing in Alpharetta, GA
HGR Plumbing handles all necessary plumbing permits and coordinates with local Alpharetta inspectors throughout the new construction process. We make sure every phase of the plumbing installation, from rough-in to final trim-out, passes inspection. Our knowledge of local regulations means your project stays compliant, avoiding delays and ensuring the long-term validity of your plumbing system.

Preventing Common Georgia Plumbing Issues in New Builds in Alpharetta, 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 resist shifting foundations and soil movement, which can stress pipes. Homes farther south often draw from deep limestone aquifers, so more mineral-heavy water and the occasional sulfur smell are common complaints there. We recommend appropriate piping materials and treatment options to minimize scale buildup over time, so your new home's plumbing lasts for decades.

Frequently Asked Questions About New Construction Plumbing in Alpharetta
The cost of new construction plumbing in Alpharetta varies a lot based on the size and complexity of the project, number of bathrooms, and fixture choices. For a standard 3-bedroom, 2-bathroom home, rough-in and finish plumbing can range from $10,000 to $25,000. Commercial projects or luxury homes with advanced systems will be higher.
We install a wide range of trusted plumbing fixture brands based on your preferences and budget, including Kohler, Moen, Delta, American Standard, and Toto. We can also accommodate specific requests if you have a particular brand or style in mind, ensuring quality and availability for your new home.
Yes, we can integrate a water softening system into your new construction plumbing design. Homes farther south often draw from deep limestone aquifers, so harder water and the occasional sulfur smell are common complaints there. A softener loop can be installed during the rough-in phase to protect your entire plumbing system and appliances from mineral buildup.
We typically use PEX-A for water supply because it handles heat and resists the scale and pinhole problems copper can develop with aggressive or hard water. Drains are usually PVC or ABS, depending on local code and builder preference. Copper is an option for mains or exposed runs when you want it.
Much of Georgia sits on heavy red clay that swells when wet and shrinks in drought, which can stress slab plumbing and sewer laterals over time. Soil that shifts and swells with moisture changes can put stress on underground plumbing. We mitigate this by using flexible piping materials and proper bedding techniques to help protect against pipe damage from soil movement.
Our workmanship is warrantied, and the warranty terms are spelled out in your contract. Fixtures, water heaters and PEX systems also carry their own manufacturer warranties, often 10 years or more for PEX and fittings from brands like Uponor. We hand over the paperwork at final.
