Fixture Installation and Trim-Out in Londonderry, NH
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 make sure all fixtures are properly seated, sealed, and functional, providing a professional finish to your new construction plumbing. We work with many brands like Moen, Kohler, and American Standard to match your design specifications.

Sewer and Water Main Connections in Londonderry, NH
Connecting your new home to the municipal sewer and water mains is a critical step in new construction plumbing. FVR Plumbing handles all aspects of these connections, including excavation, trenching, pipe laying, and backfilling. We ensure proper grading and sealing to prevent future leaks or blockages. Rocky glacial soil and shallow ledge are common in New Hampshire, which can make digging for sewer and water lines slow and expensive.
Rough-In and Top-Out Plumbing in Londonderry, NH
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 a question.
Preventing Common New Hampshire Plumbing Issues in New Builds in Londonderry, NH
New construction in New Hampshire must account for local conditions. Rocky glacial soil and shallow ledge are common in New Hampshire, which can make digging for sewer and water lines slow and expensive. We focus on installations that resist shifting foundations and soil movement, which can stress pipes. A large share of homes rely on private wells, and some wells carry naturally occurring arsenic, radon or iron that call for treatment. We recommend suitable piping materials and treatment options to minimize scale buildup over time, so your new home's plumbing lasts for decades.

We offer complete commercial new construction plumbing for businesses, multi-family units, and industrial properties.

FVR Plumbing focuses on complete plumbing system installations for new residential homes. This includes designing the layout, installing all water supply lines, drain lines, and vent piping.

Water Heater and Recirculation Installation in Londonderry, NH
New homes often 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. A large share of homes rely on private wells, and some wells carry naturally occurring arsenic, radon or iron that call for treatment. If treatment makes sense for your water, we suggest planning space for a softener or filter loop at the same time.

Frequently Asked Questions About New Construction Plumbing in Londonderry
Most new single-family homes in the Londonderry area cost between $12,000 and $25,000 to plumb, with larger custom homes running $30,000 or more. Fixture count, pipe material, water heater type and extras like recirculation or outdoor kitchens drive the final price. We provide an detailed bid from your plans.
Some jurisdictions allow owner-builders to do their own plumbing on a home they will live in, but the work still has to pass every inspection. Under-slab and gas work are the hardest to get right and the most expensive to fix later. Many owner-builders hire us for those phases and finish easier tasks themselves.
The plumbing rough-in phase for a typical residential build in Londonderry generally takes 1 to 2 weeks, depending on the crew size and complexity. The final fixture installation and trim-out usually takes an additional 2 to 4 days later in the construction schedule.
Several inspections are needed during new construction plumbing. These usually include an underground or rough-in inspection before walls are closed, a top-out inspection if applicable, and a final inspection after all fixtures are installed and the system is operational. We schedule and manage all inspections to ensure compliance.
For new construction plumbing, we primarily use PEX piping for water supply lines due to its flexibility, durability, and resistance to scale build-up. For drain, waste, and vent systems, we use PVC pipes, which are resistant to corrosion and long-lasting.
Rocky glacial soil and shallow ledge are common in New Hampshire, which can make digging for sewer and water lines slow and expensive. Soil that shifts and swells with moisture changes can put stress on underground plumbing. We reduce this by using flexible piping materials and proper bedding techniques to help protect against pipe damage from soil movement.
Yes, we can integrate a water softening system into your new construction plumbing design. A large share of homes rely on private wells, and some wells carry naturally occurring arsenic, radon or iron that call for treatment. A softener loop is easy to add during the rough-in phase to protect your entire plumbing system and appliances from mineral buildup.
We install a wide range of well-known plumbing fixture brands, including Moen, Kohler, Delta, American Standard, and Toto. We can work with any brand you specify or recommend options that fit your budget and design aesthetic for your new build in Londonderry.
