What to Look For
Common Plumber Problems in New Hampshire
Dripping faucets that waste up to 3,000 gallons per year and drive up your water bill
Running toilets caused by a worn flapper, faulty fill valve, or warped flush valve seat
Slow or clogged drains from grease buildup, hair, soap scum, or tree root intrusion
Water heater failure — the average tank water heater lasts 8–12 years before sediment buildup causes problems
Leaking or burst pipes, especially in older homes with galvanized steel or polybutylene piping
Low water pressure caused by corroded pipes, a failing pressure regulator, or municipal supply issues
Questions to Ask Before Hiring a Plumber in New Hampshire
“Can you give me a written estimate before starting any work?”
A professional plumber should be able to diagnose the issue and quote a price before turning a wrench. Verbal estimates often lead to surprise charges.
“What's your warranty on parts and labor, and does it cover the full repair or just the part you replaced?”
Some plumbers warranty only the part (which has its own manufacturer warranty anyway) but not their labor. A good warranty covers both for at least 12 months.
“Is there a less expensive option that would still fix the problem properly?”
An honest plumber will tell you if a repair makes more sense than a replacement, or if a simpler fix exists. This question reveals whether they're prioritizing your wallet or theirs.
“Do you charge a trip fee or diagnostic fee, and is it applied toward the repair cost?”
Many plumbers charge $50–$100 just to show up. Some credit that fee toward the repair if you hire them. Know this before they arrive so there are no surprises.
“Will you pull the required permits for this job?”
Major plumbing work like water heater installations or repiping typically requires a permit. If a plumber skips permits, the work may not be up to code and could cause problems when you sell your home.
Red Flags When Hiring a Plumber
- ✖Demands full payment upfront before starting work — a standard deposit is 10–25%, never 100%
- ✖Can't show you a license number or gets defensive when you ask to verify it
- ✖Wants to start work immediately without diagnosing the problem first or explaining what they'll do
- ✖Quotes significantly below every other plumber — they may be cutting corners, using substandard parts, or planning to upsell once the job is started
DIY vs Hiring a Professional Plumber
You can handle simple fixes like replacing a flapper valve in a toilet tank, swapping a showerhead, or tightening a loose faucet handle. But anything involving your main water line, water heater, gas connections, sewer line, or work behind walls requires a licensed plumber. DIY plumbing mistakes can cause thousands in water damage and may void your homeowner's insurance if the work wasn't done by a licensed professional.
Plumber Safety Tips
- Never attempt to repair or install gas water heaters or gas lines yourself — gas leaks can cause explosions and carbon monoxide poisoning
- Avoid using chemical drain cleaners repeatedly as they corrode pipes from the inside and can cause them to fail prematurely
- Know where your main water shutoff valve is before an emergency — if a pipe bursts, every second counts
Best Time to Hire a Plumber in New Hampshire
Plumber demand spikes in late fall and winter when freezing temperatures burst pipes and water heaters work overtime. Schedule preventive maintenance in early fall — have your water heater flushed, check outdoor hose bibs, and insulate exposed pipes before the first freeze. Spring is the second peak season when snowmelt reveals cracked sewer lines and sump pumps get overwhelmed.
Plumber Licensing in New Hampshire
Plumbers are licensed in all 50 states. Most states have tiered licensing — apprentice, journeyman, and master plumber. For residential work, a journeyman license is typically sufficient. Always verify the license is active and check for complaints with your state licensing board.
