What's on a kitchen maintenance checklist?
Updated August 2026
A kitchen stays trouble-free on a few monthly cleanings and one yearly leak check: rinse the range-hood and dishwasher filters and freshen the disposal each month, then once a year vacuum the refrigerator coils, re-caulk the sink, and feel every under-sink supply line for damp. The tasks are small; the failures they head off, a flooded cabinet or a compressor cooked by dust, are the pricey ones.
| Task | Interval | Effort |
|---|---|---|
| Degrease the range-hood filter (dishwasher or a hot soak) | Monthly | 10 min · DIY |
| Clean the dishwasher bottom filter and run a cleaner cycle | Monthly | 15 min · DIY |
| Freshen the disposal with ice and citrus under cold water | Monthly | 5 min · DIY |
| Task | Interval | Effort |
|---|---|---|
| Wipe the refrigerator door gaskets and check the seal | Every 6 months | 10 min · DIY |
| Replace the fridge water and ice filter | Every 6 months | $30–60 · DIY |
| Task | Interval | Effort |
|---|---|---|
| Vacuum the refrigerator condenser coils | Yearly | 15 min · DIY |
| Feel under-sink and dishwasher supply lines for leaks | Yearly | 5 min · DIY |
| Re-caulk the sink rim, faucet base, and backsplash seam | Yearly | 30 min · DIY |
| Exercise the sink and dishwasher shutoff valves | Yearly | 5 min · DIY |
What neglect costs
Dust on the refrigerator coils makes the compressor run hot and long, shaving years off a fridge that should reach 10 to 15, and a failed compressor often costs more than the appliance is worth. Under the sink, a braided line or a dishwasher hose that lets go while you are out floods the cabinet and the floor beneath; the water damage routinely runs into the thousands, and if it reaches a finished basement the bill lands around $2,000–8,000. The cheap insurance is the yearly hand-check and swapping any rubber hoses for braided steel.
Leave these to a pro
Most of this list is DIY, but a few things earn a pro. A gas range with a gas smell or a lazy yellow flame needs a technician, not a scrub. A leak that returns after you re-caulk points to a supply valve or drain fitting a plumber should replace, usually $150–350 a visit. And an appliance tech at $100–200 a call is far cheaper than a new refrigerator when a fan or relay, not the compressor, is the real fault. Re-caulking technique carries over from the bathroom checklist.

How often should I clean my refrigerator coils?
Every 6 to 12 months for most homes, and closer to every 3 months if you have shedding pets, since fur mats onto the coils fastest. The coils shed the heat the fridge pulls out of your food; when dust blankets them, the compressor runs hotter and longer to keep up, which drives the energy bill up and the appliance's life down. Unplug it, find the coils behind the kick plate or on the back, and vacuum with a brush attachment plus a coil brush for the tight rows.
Why bother checking under the kitchen sink?
Because it is where the slowest, most expensive leaks start. Supply lines, the dishwasher hose, the P-trap, and the disposal connection all live in that dark cabinet, and a weep from any of them can rot the cabinet floor and the subfloor for months before you notice a smell or a warp. A five-minute hand-check once a year, running your fingers along each fitting for damp, catches it while it is still a tightened nut and not a flooring job.
How often should I re-caulk around the kitchen sink?
Once a year, and immediately if the bead is cracked, peeling, or dark with mildew. The seal around a drop-in sink rim, at the faucet base, and along the backsplash keeps splashed water from running down behind the counter into the cabinet and the wall. For the grouted backsplash tile behind the counter, the same seal-and-inspect rules apply as anywhere else; see the tile and grout checklist for resealing.
