Full-Service Plumbing, Drain, Heating, and Emergency Response

Which page do I need?

Find the line that matches what you can see or hear, and follow it; each symptom goes to the one page that explains that job, so you are not reading three pages to find the right one.

One sink, tub or shower drains slowly or not at all

Drain cleaning — A single fixture backing up is a branch-line clog. It is cleared from that fixture, and the page explains what we use and what it costs.

Several drains back up at once, or water comes up in the basement

Sewer line services — When the lowest drain in the house is the one overflowing, the main line is blocked. That is a sewer call, not a sink call.

The same main-line clog keeps coming back

Hydro jetting — A cable opens a hole through grease or roots; jetting scours the pipe wall. A clog that returns every few months is the case for it.

You want to see what the pipe actually looks like before paying for a repair

Sewer camera inspection — A camera shows roots, breaks, bellies and offsets, and where they are. It is how a sewer repair gets priced honestly.

No hot water, or hot water that runs out fast

No hot water — Thermocouple, element, gas valve, dip tube, or a tank that has simply aged out. The page walks the causes in order.

Water on the floor under the water heater

Leaking water heater — A leak from a fitting is a repair; a leak from the tank seam is a replacement. The page tells you how to tell them apart.

Your water heater is old and you are deciding whether to replace it

Water heaters — Tank or tankless, repair versus replace, and what the next unit should be. Cost ranges are on the replacement cost page linked below.

A tankless unit shows an error code

Tankless water heaters — Descaling, flow and venting faults, and the brand pages for Navien and Rinnai codes hang off this one.

No heat, or the boiler short-cycles or will not fire

Boiler repair — No-heat diagnostics, parts, and the safety checks that go with a gas boiler. Heating season is when this page is busiest.

You are choosing or replacing a heating system

Heating and boiler service — The planning page: boilers, gas heat, and ductless mini-splits compared for a South Shore house.

A burst pipe, water you cannot shut off, or sewage in the house

Emergency plumbing — What to shut off first, what to do before we arrive, and the one line that is answered around the clock.

A pipe has frozen, or you are worried one will

Frozen pipes — Thawing without bursting, and where South Shore houses freeze first.

A wet spot or a water bill with no visible leak

Leak detection — Finding the leak in a wall, slab or ceiling before anything is opened up.

A stain or drip in the ceiling under a bathroom

Ceiling leak repair — Usually a toilet seal, a tub drain or a supply fitting above. The page explains how the source is found from below.

Weak pressure at every tap in the house

Low water pressure — A pressure-reducing valve, a corroded main, or a failing shutoff. Whole-house pressure is a different problem from one slow faucet.

A toilet runs, rocks, leaks at the base, or clogs again and again

Toilet repair and installation — Fill valves and flappers, flanges and wax rings, and when a replacement makes more sense than another repair.

The disposal hums, jams, or leaks underneath

Garbage disposal — Jam clearing, a seized motor, or a replacement; and the drain-cleaning page if the clog is past the disposal.

The sump pump runs constantly, never runs, or you want a backup

Sump pumps — Testing, replacement and battery backup before the storm, not during it.

You need a gas line for a range, dryer, grill or heater

Gas lines — Installation, extension and repair, and the license that covers it. A gas smell is a safety call, and the page says who to call first.

A dripping faucet, a new fixture, or a plumbing inspection before a sale

General plumbing — The everyday calls: fixtures, shutoffs, small leaks, and the inspection a buyer wants.

You are building, adding on, or gutting a kitchen or bathroom

New construction plumbing — Rough-in, fixture set, gas piping and inspections, coordinated with your builder.
