A cabinet can hold faucet supplies, basin seals, drain fittings, a disposal, dishwasher connections, and electricity. The first damp point and operating stage make the inspection brief useful.
Call a plumber877-702-1610Observe first. Let the responsible party identify the cause.Season and setting
Season does not change the basic method: dry only safely reachable surfaces, run no more water than the cabinet can contain, and stop before moisture spreads.
Decision path
Note whether water starts during hot or cold flow, basin filling, basin drain-down, disposal use, dishwasher pump-out, or idle time.
Prepare for the visit
Do not pull an appliance, reach behind powered equipment, turn a stiff valve, or dismantle a trap. Preserve prior cleaner use for the provider.

Basin edge
Check rim, deck, and bowl surfaces during ordinary contained use.
03
Drain window
Observe accessible joints only while water leaves the basin.
04
Appliance link
Tie disposal or dishwasher operation to the first visible cabinet change.

Electrical stop
End the observation before water reaches a receptacle, switch, cord, or powered device.

ProviderInspection finding, proposal, work, and warranty
Public sourceUtility, permit, inspection, or credential record
Adjacent workElectrical, appliance, cleanup, drying, and finishes
Closeout record
Keep enough detail for the next household decision
Closeout should divide plumbing repair, appliance service, electrical assessment, cabinet drying, shelf replacement, and concealed areas that were not inspected.
