Overview
Disposals wear out from the inside: seals fail, the housing rusts and water starts dripping into the cabinet. Once the bottom leaks, replacement is the only fix. A new unit may sit at a different height, so the trap and tailpiece often need adjusting to keep the drain sloped downhill.
We install the unit on a fresh mount, connect the dishwasher drain, rebuild the trap if needed and test for leaks. We can help you pick a size: a half or three-quarter horsepower model handles most homes.
How we handle it
Remove the old unit
Mount, drain and wiring checked.
Mount the new one
New flange seal, dishwasher tie-in.
Adjust the drain
Trap reworked for proper slope, then tested.
What it costs
Like-for-like replacements are quick. First-time installs, a dishwasher tie-in or reworking the trap take longer. Electrical work, if needed, is done by an electrician.
Good to know
- Choose a unit with a stainless grinding chamber for longevity.
- Look for sound insulation if the kitchen is open to living space.
- Keep the original box for the warranty paperwork.
If your home is on septic, common in parts of Helotes, choose a septic-rated disposal and use it lightly.

What size disposal should I get?
Half or three-quarter horsepower suits most homes.
Can you add one where there was none?
Yes, if power is available under the sink.
How long does a disposal last?
Often 8 to 12 years depending on use and quality.
