Sewer Repair
Tree roots, cracked clay pipe and repeat backups in the line from your house to the street.
A showerhead that drips all day, a handle that won't turn or water that goes cold when someone flushes. We repair shower valves, cartridges, heads and drains, with a flat price before we start. From our headquarters on Techny Road.

Most shower problems start in the valve behind the wall:
A worn cartridge or washer lets water through even with the handle off.
A pressure-balancing valve that's worn out can't adjust when another fixture pulls water.
A clogged showerhead is an easy fix. Weak flow in the whole bathroom points to the pipes or a partly closed valve.
Worn stems and cartridges make handles loose, stiff or useless.
Northbrook's housing spans nearly a century, and the shower valve behind your tile usually tells us which decade the bathroom was last remodeled.
Postwar bathrooms often still have separate hot and cold handles. They can be repaired, but parts can be hard to find. We'll tell you whether a repair will hold or a new valve makes more sense.
In two-story homes, a shower on the second floor shares supply lines with bathrooms below. If pressure drops when another bathroom is in use, the valve or the line size may be the cause.
In homes built before the 1970s, galvanized supply lines narrow over time. If the whole bathroom is weak, the pipe may be the real problem.
We fix the shower without turning it into a remodel you didn't ask for.
Your plumber explains what's wrong in plain English first, then walks you through your options. You decide.
You get a flat-rate price before we touch anything, with no surprise add-ons when the job is done.
Shoe covers on, work area protected, and the space cleaned up before we leave.

Often, yes. Many repairs are done through the trim opening. A full valve replacement sometimes needs access from behind or a larger trim plate. We'll explain before we start.
Usually a worn pressure-balancing valve. Sometimes it's the water heater or line size.
Usually it's a pressure-balancing valve that's worn out and can't adjust when another fixture pulls water. In larger homes, a water heater that's too small or a supply line that's undersized can add to it. See water heater repair.
