Plumbing Repairs & Service

Leaks, clogs, failing valves, and the 2 a.m. calls. The everyday plumbing work that keeps a house running.

Plumbing Repairs and Service
The short version

What to expect

Most plumbing calls start the same way: something is dripping, backing up, or making a noise it never made before. We show up with the parts and the diagnostic tools to find the actual cause, not just the symptom, and we tell you what we found before we start spending your money. Some of it is a ten-minute cartridge swap. Some of it is a repipe that should have happened five years ago. Either way you get a straight answer, a price before the work, and a crew that respects your floors, your schedule, and your basement.

Plumbing Repairs & Service

Leaks, running toilets, failing shutoffs, and pipes that bang when the washer fills. We diagnose the actual cause instead of guessing, repair it correctly the first time, and clean up after ourselves.

Emergency Plumbing Repairs
Emergency call

Emergency Plumbing Repairs

Burst pipe at midnight, frozen line in February, water heater letting go on a Sunday. We take urgent calls, stop the damage fast, and get water back where it belongs so your home stays dry.

Drain, Waste and Vent Piping
Repair or replacement

Drain, Waste & Vent Piping

Slow drains and sewer odor usually trace back to venting or pitch, not the fixture. We repair, replace, and reroute DWV piping so waste moves out and air moves in the way the code requires.

PEX and Copper Repiping
Whole-home project

PEX & Copper Repiping

Pinhole leaks and old galvanized lines do not improve with age. We repipe whole homes in PEX or copper, work section by section, and keep wall damage to the minimum the layout allows.

Sump Pumps
Installation

Sump Pumps

A basement stays dry because a pump works, not because one is installed. We size, set, and pipe sump systems with proper check valves, discharge routing, and battery backup that holds in a storm.

Outdoor Faucets and Plumbing
Installation

Outdoor Faucets & Plumbing

Frost-free hose bibs, irrigation supply lines, pool fills, and barn spigots. Set at the right pitch with accessible shutoffs so a New Hampshire cold snap does not split them open behind the siding.

Appliance Plumbing Connections
Service call

Appliance Plumbing Connections

Dishwashers, ice makers, washing machines, and pot fillers connected with new shutoffs, air gaps, and braided supply lines. Done right so a forty dollar hose never ruins a nine thousand dollar floor.

Fixtures and water treatment

A few minutes of recent service work: a softener set installed under the stairs, faucet and shower valve replacements, and the finished trim left clean enough to photograph.
