Whether you're building a new home in New Hampshire, finishing a basement, adding a bathroom, or replacing failing old pipes throughout your house, proper pipe installation is foundational to a plumbing system that will perform reliably for decades. Plumbing HVAC Services New Hampshire provides expert pipe installation and repiping services for residential and commercial properties throughout the Granite State.
Pipe Installation Services We Provide
Pipe Materials We Install
PEX (Cross-Linked Polyethylene)
PEX has become the preferred pipe material for most residential plumbing applications in New Hampshire for good reason: it's flexible, freeze-resistant, highly durable, easier to install than rigid pipe, and significantly less expensive than copper. PEX comes in three types — PEX-A (most flexible, best freeze resistance), PEX-B (most common, excellent value), and PEX-C. We use PEX-A and PEX-B from quality manufacturers including Uponor, Viega, and SharkBite.
For NH homes, PEX's freeze resistance is a major advantage. While PEX can still freeze and burst under prolonged extreme cold, it has significantly more tolerance than copper or CPVC and bounces back better from temporary freezing.
Copper Pipe
Copper remains the gold standard for visible plumbing work, commercial applications, and homeowners who prefer it. It's durable, naturally antimicrobial, and rated for 50+ years of service. Type L copper is standard for most residential supply lines; Type K is used for underground applications. We solder all copper fittings to code using lead-free solder.
CPVC & PVC
CPVC (chlorinated PVC) handles hot and cold water lines in residential applications. Standard PVC is used for drain, waste, and vent (DWV) systems. Both are cost-effective, corrosion-resistant, and durable when properly installed with appropriate primers and cements.
Whole-Home Repiping in New Hampshire
Homes built before 1970 in New Hampshire often have original galvanized steel pipes that are well past their service life. Signs you may need whole-home repiping include rust-colored water, frequent pipe leaks, significantly reduced water pressure throughout the home, and visible corrosion on exposed pipes.
Whole-home repiping is a major project but can often be completed in 2–4 days with minimal disruption. We work systematically room by room, restoring water supply at the end of each workday so you're not without water overnight.

New home plumbing in New Hampshire requires NH plumbing permits and inspections at rough-in and final stages.

We work with custom builders, general contractors, and individual homeowners on projects of all sizes.
Pipe Installation FAQs
For most NH residential applications, PEX-A or PEX-B is our top recommendation — flexible, freeze-resistant, durable, and cost-effective. Copper is preferred for visible or exposed runs and commercial use. CPVC is a good mid-range option. We'll recommend the right material for your specific application and budget.
A typical 2–3 bedroom NH home takes 2–4 days depending on size, layout, and pipe access. We work systematically and restore water each evening so you're not without service overnight.
Repiping costs vary significantly based on home size, pipe material chosen, accessibility, and whether the project includes fixture replacements. A typical NH home ranges from $4,000–$15,000. We provide detailed written estimates after assessing your home.
Yes — any significant plumbing work including new construction rough-in, additions, and whole-home repiping requires NH plumbing permits. We pull all required permits and coordinate inspections as part of every project.
PEX is more freeze-resistant than copper or CPVC, but it can still freeze and burst under prolonged extreme cold. The key is adequate insulation of pipes in exterior walls, crawl spaces, and unheated areas — which we address as part of any installation project.
