How Much Does Grease Trap Cleaning Cost?

“How much does it cost to clean a grease trap?” is one of the first things kitchen owners ask — and the honest answer is: it depends. Rather than quote a number that won’t match your kitchen, here’s a clear breakdown of what actually drives the price, so you know what you’re paying for.

What Affects the Price

• Trap or interceptor size. A small 25-gallon under-sink trap is a very different job from a 1,500-gallon in-ground interceptor. More volume means more time, equipment, and disposal.
• Service frequency. Traps on a regular schedule are faster and cheaper to service than a neglected trap that’s hardened and overflowing.
• Accessibility. Easy-to-reach lids cost less than traps that are buried, downstairs, or tucked behind equipment.
• Volume of grease & solids. The more that has to be pumped and hauled, the higher the disposal cost.
• Emergency vs. scheduled. After-hours emergency call-outs for a backup cost more than a planned visit.

Why a Maintenance Plan Costs Less

The single biggest way to control cost is to stay on a schedule. A trap serviced before it hits 25% capacity is a quick, predictable job. A trap that’s been ignored can harden, clog the outlet, back up into the kitchen, and even damage your drain lines — turning a routine cleaning into an emergency plus repairs. Recurring maintenance also spreads the cost into predictable amounts you can budget for, instead of surprise bills.

The Hidden Costs of Skipping Service

• Health-code violations and FOG fines
• Kitchen downtime during a backup — lost revenue on your busiest nights
• Emergency call-out fees
• Drain-line and plumbing repairs from overflow damage

Against those, routine cleaning is almost always the cheaper path.
