Pipe Repair for Boston homes

Leak detection and pipe repair, from a single failed joint to replacing a run of corroded supply line. Older homes here often still have original galvanized piping.

Most of our Boston work is in Dorchester, South Boston and the neighborhoods south of downtown, dispatched from our Quincy office minutes up Route 93. Triple-deckers and rowhouses with original cast-iron stacks, shared sewer laterals, and basement water heaters that serve three units at once are the everyday call here.

When to call us

  • Damp spots, stains, or bubbling paint on a wall or ceiling
  • A water bill that jumped with no change in use
  • Visible green or white corrosion on copper joints
  • Low pressure at one fixture but not the rest of the house

How does a pipe repair visit go?

A pipe repair visit starts with finding the actual leak, which is rarely where the water shows up. Water runs along a joist, a pipe or the top of a wall and appears a room away, so the plumber traces back from the wet spot to the fitting or pipe it came from before anything is opened. Pressure testing a section, listening at fittings and checking the meter with every fixture closed all come before a hole is cut.

Once the failure is found you are shown it and told what the repair involves: a single fitting, a short section spliced in, or a longer run replaced because the pipe around the failure is in the same condition. The repair is pressure tested before the wall is closed, and the plumber checks the rest of the run while the wall is open, because the second pinhole in a corroded line is usually a foot from the first.

Boston calls for pipe repair are scheduled from our Quincy office, and whichever office sends the crew, the work is done under the same Massachusetts plumbing license.

What decides the cost of a pipe repair?

The cost of a pipe repair is decided by access first and material second. A fitting in an open basement ceiling is reached in minutes; the same fitting behind tile, under a slab or inside a finished ceiling means opening and later closing that finish, and the opening is most of the job. Leak detection is its own line when the source is not obvious, and it is cheaper than opening the wrong wall.

After access, the price follows how much pipe is replaced and what it is made of. Copper, PEX and galvanized steel each join differently, and old galvanized or thin-wall copper often cannot take a new fitting without the joint next to it failing, which is why a short repair sometimes becomes a longer section. Whether water can be isolated to one branch or the whole house has to be shut down, and whether a permit is needed for the extent of the work, both move it as well.

Where the job needs a permit, it is filed with Boston's plumbing and gas inspector before the work, and the permit fee is set by the town rather than by us.

The $99 service fee sends a licensed technician out to diagnose the problem. Approve the repair on the spot and the fee is not charged at all; decline it and the $99 covers the visit.

Should I repair one section of pipe or repipe the house?

Repair the section if the pipe around the failure is sound; repipe when the same run has failed more than once or the material has reached the end of its life everywhere at once. One pinhole in otherwise clean copper is a repair. A second and third pinhole in the same run within a year is the pipe telling you the wall thickness is gone along its whole length.

Galvanized steel is the clearest case. It corrodes from the inside, narrows until pressure at the far fixture drops, and the first leak usually means the rest is not far behind, so replacing a galvanized run outright is often the lower total cost. Copper with a single mechanical failure, a frozen split or a bad original joint is worth repairing. We will tell you which you have while the wall is open, when the evidence is in front of both of us.

We have worked in hundreds of Boston homes, and the answer in one house is not always the answer next door: the recommendation follows what the system in front of us is doing, not a rule of thumb.

What should I do before we arrive for a pipe repair?

Close the nearest shut-off, or the main if you cannot isolate the leak, and note everything you have seen: where the water appeared, when it started, whether it is worse when a particular fixture runs. That history shortens the search more than anything else.

Clear the area around the wet spot and, if it is a ceiling, move furniture and put a bucket under the lowest point rather than poking a hole that lets the whole pooled volume out at once. Clear access to the basement, to the main valve and to the water meter, because checking the meter with everything closed is one of the first tests. If the house still has its original galvanized or early copper piping and you know roughly when it was built, tell us; it changes what fittings and pipe go on the truck.

If anything about your Boston address is hard to find, such as a shared driveway or a basement door around the back, tell the Quincy office when you book so the crew is not hunting for it.

Pipe Repair in Boston, in practice

Leak detection is the pipe job we are called out for most in Boston, more often than the repair that follows it. In a triple-decker the leak is almost never where the stain is: water runs along a joist and appears two rooms away, and the riser it came from feeds three apartments rather than one. Most of our Boston work sits in South Boston, Dorchester, Mattapan, Jamaica Plain and Roslindale, where supply runs are long, shared between units, and buried behind finished walls. Finding the failure honestly, before anything gets opened up, is most of the job.
