Grease Trap Cleaning Cost Estimator
Get an accurate price range for grease trap cleaning based on trap size, type, service region, and disposal method. Updated with 2026 contractor pricing across North America.
Know What You Should Pay Before You Call
Grease trap cleaning prices vary significantly depending on trap size, waste volume, regional disposal costs, and whether you're on a scheduled service contract or calling for a one-off pump-out. Restaurant owners who don't know the typical range often overpay — or get quoted a suspiciously low price that doesn't include waste manifest handling or hauling fees.
This estimator uses pricing data aggregated from verified contractors across the US and Canada. Enter your trap size, type, and location to get a realistic low-to-high range with a mid-range breakdown. For an exact quote, use the contractor search to find a verified operator in your area.
Note: These are market-rate estimates based on contractor data. Actual pricing depends on local disposal regulations, hauling distance to approved facilities, and your service contract terms. Emergency and after-hours calls typically add 25–50% to base rates.

Factors That Affect Your Price
What Drives Grease Trap Cleaning Costs
Trap size is the single biggest cost driver — a 50-gallon under-sink passive trap takes 30 minutes to service, while a 5,000-gallon outdoor interceptor requires a vacuum truck, multiple technicians, and a separate waste manifest for each load hauled to an approved facility.
Disposal costs vary dramatically by region. States with strict FOG disposal regulations (California, New York, Texas) have fewer licensed receiving facilities, which drives up hauling fees. In regions with looser oversight, disposal costs are lower but the service quality can vary more.
Service contracts reduce your per-visit cost by 15–30% compared to on-demand calls. Contractors build in route efficiency on scheduled stops — your price reflects that. Emergency calls carry a premium because they displace scheduled work and often require after-hours dispatch.
Waste manifest handling is a hidden cost many restaurant owners miss. Under 40 CFR Part 503, non-domestic waste (which includes FOG) must be tracked with a manifest from collection to disposal. Contractors who handle this properly charge for it — and you should want them to, because improper disposal can result in fines traced back to the generator (you).
Common Questions About Grease Trap Cleaning Costs
Based on pricing data from verified contractors across North America.
The standard rule is the 25% rule: clean your trap when the combined depth of FOG and solids reaches 25% of the trap's total liquid capacity. For most commercial kitchens, this means cleaning every 1–3 months. High-volume operations (fast food, institutional kitchens) may need monthly or even bi-weekly service. Some municipalities mandate a minimum cleaning frequency regardless of grease accumulation.
The biggest variable is disposal cost — licensed FOG receiving facilities charge differently by region, and hauling distance adds up. Other factors include whether the contractor provides a waste manifest (required for compliance), whether their trucks are properly licensed, and whether their quote includes labour, disposal, and callout in one line item or splits them. A $150 quote that excludes disposal can end up costing more than a $250 all-in quote.
For most commercial kitchens, yes. Contracts typically reduce per-visit cost by 15–30%, ensure you stay compliant without having to remember to schedule service, and some contractors include documentation for municipal FOG reports as part of the contract. The break-even point is usually 3–4 visits per year — if you need service that frequently, a contract saves money and reduces administrative burden.
A proper service includes pump-out of accumulated FOG and solids, cleaning of baffles and interior surfaces, inspection of inlet and outlet pipes, measurement and recording of grease depth (for the 25% rule documentation), and a service report. Some contractors also provide a waste manifest for compliance purposes. Always ask what's included before accepting a quote — bare-minimum operators skip the inspection and documentation steps.
For small passive under-sink traps, some jurisdictions allow self-cleaning with approved disposal at a licensed facility. For any grease interceptor (outdoor, in-ground), self-cleaning is typically prohibited — the waste is classified as non-domestic, requires a licensed hauler, and must be disposed of at an approved FOG receiving facility with proper manifest documentation. Check your local municipal FOG ordinance before attempting self-service.
