Drain Cleaning
Slow, gurgling or backed-up drains in kitchens, bathrooms and basements.
A dripping showerhead, a handle that won't turn or water that swings from hot to cold. We repair shower valves, cartridges, heads and drains, with a flat price before we start. Serving Highland Park and the North Shore.

Most shower problems come from the valve behind the wall, not the parts you can see:
A worn cartridge or washer in the valve lets water through even when the handle is off.
Water that runs hot then cold, or never gets hot, points to a worn cartridge or a failing pressure-balancing valve.
A clogged showerhead is easy. If the whole bathroom is weak, older pipes or a partly closed valve may be the cause.
Handles that are hard to turn, spin freely or broke off usually need a new cartridge or stem.
Nearly half of Highland Park homes were built before 1960, and many bathrooms still have their original shower valves behind the tile.
Older valves can still be repaired, but parts can be harder to find. We'll tell you if a repair will hold or if replacing the valve makes more sense.
Galvanized water lines narrow with corrosion over the decades. If pressure is weak at every fixture, the pipes 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.
