Signs of a kitchen sink blockage
Kitchen clogs build up from grease, food and soap, so they often start slow and get worse over a few days.
- Water drains slowly or stands in one or both basins
- Water returns when the dishwasher drains
- The blockage persists even when the disposal is not used

Call (720) 731-0399Finding where the kitchen drain is blocked
The provider should establish the likely obstruction location and select an appropriate access point. Ask whether the visit includes trap removal, cable clearing, and reassembly checks. If the drain repeatedly blocks, discuss what further investigation would explain the cause instead of assuming a new disposal will solve it.
What a kitchen sink quote should cover
The fix may involve the trap, the disposal or the line in the wall, so ask which parts the visit includes.
- Drain access and clearing method
- Disposal or dishwasher connection checks
- Reassembly and leak checks
- Further investigation if the blockage returns
Before you call about the kitchen sink
- Whether one basin or both are holding water
- Whether the dishwasher drains back into the sink
- Whether you have a garbage disposal and if it hums, runs or stays silent
- Any drain cleaner already used
While you wait
Stop running the dishwasher and disposal. Clear the cabinet under the sink so the provider can reach the pipes.
Price depends on access, parts and what the assessment finds, so ask for a written quote before you approve any work.
Questions about kitchen sink unclogging
Is a clogged sink always a disposal problem?
No. The obstruction may be beyond the disposal or in a sink without one. Tell the provider whether water backs up in the second basin and whether other nearby fixtures are affected.
Should I use a chemical drain opener first?
Let the provider know if a product has already been used and avoid mixing or adding products. Standing water and chemical residue can complicate safe access to the drain.
Why does my sink fill up when the dishwasher runs?
The dishwasher usually drains through the sink’s drain or the disposal. If that shared path is partly blocked, water backs up into the sink first.
