Sink, disposal, dishwasher.
Get the kitchen working.

The kitchen is the heart of the home and one of the busiest plumbing areas in the house, so we know how much a problem there disrupts your day. From a clogged sink to an under-cabinet leak, we handle every kitchen plumbing job and explain the fix before we start.

Common kitchen calls

What we fix most often.

  • Garbage disposal repair or replacement: humming but not turning, leaking, or completely dead
  • Faucet replacement: single-handle, double-handle, pull-down, touch-activated
  • Sink replacement: drop-in, undermount, single or double basin
  • Dishwasher install: supply line, drain, air gap, electrical coordination
  • Ice maker line: refrigerator water/ice connection
  • Instant hot water dispenser install
  • Drain unclogging: from a slow sink to a line that keeps clogging
  • Leak under the sink: supply line, drain trap, or disposal seal
What we see most

The kitchen sink works harder than any drain in the house.

Grease, food scraps, coffee grounds and soap all go down the kitchen line, and over the years they build up inside the pipe. A plunger or store-bought cleaner may open a hole for a while, but the buildup stays. When a kitchen clog keeps coming back, we clean the line itself, and hydrojetting is often the right tool for that.

Under the sink is a busy place too: the disposal, the dishwasher drain, the supply lines and the trap all meet in one cabinet. A slow drip there can soak the cabinet floor for months before anyone notices, so we check every connection while we are there.

How a visit goes

We fix it right, and leave your kitchen clean.

  • We find the cause: a clog, a failed disposal seal, a loose trap or a worn supply line each need a different fix
  • You get options in writing: repair or replace, with a flat-rate price for each, before any work begins
  • We protect your kitchen: cabinet contents set aside with care, floors covered, and everything cleaned up when we finish
  • We label your shut-offs: every one we find, including the ones under the sink, so you can close them fast next time
Help your kitchen drain

Keep it flowing between visits.

  • Grease goes in the trash, not the sink: let it cool, wipe the pan, and throw the paper towel away
  • Run cold water with the disposal: before, during and after, so scraps keep moving
  • Keep problem scraps out: celery, corn husks, onion skins, eggshells and coffee grounds clog traps
  • Watch the cabinet floor: a damp or warped cabinet base is often the first sign of a slow leak

Common Questions

Frequently asked questions.

My garbage disposal hums but won't turn. Is it broken?
Not always. A humming disposal is usually jammed. Turn it off at the switch first, and never put your hand inside. Many disposals have a reset button underneath and a hex socket on the bottom for freeing the motor. If it still won't turn, or it leaks from the bottom, call us and we will tell you whether a repair or a new unit makes more sense.
Why does my kitchen sink keep clogging?
Grease and food build up inside the drain line over time. Clearing the trap helps for a while, but the buildup further down the line stays. Hydrojetting cleans the inside of the pipe, which is why it often stops repeat clogs.
Can you install a dishwasher or connect an ice maker line?
Yes. For a dishwasher, we connect the water supply and the drain, and make sure the drain is set up so dirty water can't flow back into the dishwasher. For an ice maker, we connect the refrigerator's water line and check it for leaks.
There is water in the cabinet under my sink. What should I do?
Close the shut-off valves under the sink, put a bucket or towels down, and call us. The leak is usually a supply line, the trap, the disposal or the dishwasher connection, and we check them all.
Do you replace kitchen faucets and sinks?
Yes, including pull-down and touch faucets, and drop-in or undermount sinks. We also check the shut-off valves and supply lines while we are there, because old supply lines are a common source of leaks.
