Cooking fat that reaches the hood is meant to stay there: baffle filters channel it into a gutter or a small cup, and mesh filters hold it until they are washed. When those fill, the grease has nowhere to go. It runs to the lowest edge of the canopy and drips back onto the burners, where it can smoke and flare, and onto the cooking surface or the counter. Water joins it too. Long boiling or steaming sends warm, wet air up the duct, and in winter that air condenses on a cold duct, especially one running through an unheated attic or a long level run to an outside wall; the water collects grease on the way down and drips out of the hood as brown, oily drops. A damper that does not close lets cold air sit in the duct and makes that condensation worse, and a missing or poorly sealed outside cap can let rain run in. A hood that drips grease is also telling you there is more of it inside, in the blower and the duct, and that is fuel above a flame. The 6 causes, cheapest first Answer these first 01 Is it thick grease, oily water, or clear water? 02 Does it drip from the filters, the canopy edge, or the chimney cover above? 03 Does it happen mostly in winter, after long boiling or steaming? 04 When were the filters last cleaned, and do they have a grease cup or gutter to empty? 05 Does the duct run through an unheated attic, a cold wall or a long level stretch? ## Check these before you book. Range hood dripping grease: 5 checks, and none of them costs anything. 01 Take out the filters, empty any grease cup or gutter, and wash the filters in hot water with degreasing soap. 02 With the hood off and cool, wipe the underside of the canopy with a degreaser and look for grease pooling at the edges. 03 Run the fan for ten minutes after long boiling or steaming, so wet air clears the duct before it cools. ### Also worth checking - Keep grease from dripping onto a lit burner: turn the burner off, wipe the drip and clean the filters before cooking again. - Book a visit with the model number from behind the filters if the dripping returns with clean filters, and say where the duct runs. ### How soon does it need a visit? Not urgent, but grease falling onto a lit burner can smoke and flare. Clean the filters and the canopy before the next pan of hot oil, and keep a lid at hand until the drip is fixed. ## The causes, cheapest first. 6 things grease or oily water dripping from the range hood turns out to be, from filters or grease cups full to a duct sloped back toward the hood. [The cost guide](https://rangehooderepair.center/cost/) 1. 01 no repair ### Filters or grease cups full Baffle filters feed a gutter or cup that needs emptying; mesh filters hold grease until they are washed. Full ones overflow at their lowest edge. [Fixed by range hood filter and baffle service](https://rangehooderepair.center/services/range-hood-filter-and-baffle-service/) 2. 02 low ### Grease built up inside the canopy Fat that gets past the filters coats the inner walls and runs down to the edge. A deep clean of the canopy and the blower housing ends the drip and lowers the fire load. [Fixed by range hood filter and baffle service](https://rangehooderepair.center/services/range-hood-filter-and-baffle-service/) 3. 03 low to moderate ### Condensation in a cold duct Warm, wet air from the pans condenses on a duct in a cold attic or wall and runs back into the hood. Insulating the duct or shortening a cold stretch is the usual fix. [Fixed by range hood damper and duct repair](https://rangehooderepair.center/services/range-hood-damper-and-duct-repair/) 4. 04 low to moderate ### A damper that does not close When the backdraft flap stays open, cold outside air sits in the duct and the next batch of steam condenses there. The damper is freed or replaced. [Fixed by range hood damper and duct repair](https://rangehooderepair.center/services/range-hood-damper-and-duct-repair/) 5. 05 moderate ### Rain entering at the outside cap A missing flap, a cracked cap or a gap in the roof or wall flashing can let rain run down the duct. The cap is repaired; roof work is arranged with whoever handles the roof. [Fixed by range hood damper and duct repair](https://rangehooderepair.center/services/range-hood-damper-and-duct-repair/) 6. 06 moderate to highest ### A duct sloped back toward the hood A duct that runs downhill toward the hood carries every drop of condensation and grease back into it. It is rerouted with a slope toward the outside where the route allows. [Fixed by range hood damper and duct repair](https://rangehooderepair.center/services/range-hood-damper-and-duct-repair/) ## What else it could be. Most often confused with cold draft or a flapping damper through the range hood, then range hood runs but barely pulls smoke.

Warm, moist air from cooking condenses on a cold duct. The water runs back into the hood, picking up grease on the way, and drips from the canopy. ### How often should baffle filters be cleaned? About monthly with regular cooking, more often with heavy frying. Many baffle filters can go in a dishwasher, which the manual confirms. ### Is the dripping grease a fire risk? Yes, if it drips onto a lit burner or builds up where a flame reaches it. It also means more grease sits inside the hood and duct. ### Can the duct be insulated to stop the dripping? Often yes, where it runs through a cold attic or wall. A short, sloped route to the outside also helps the water drain away from the hood. --- **[Read on the site: Grease or Oily Water Dripping From the Range Hood: Causes and Fixes](https://rangehooderepair.center/problems/range-hood-dripping-grease/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
