What Grease Trap Cleaning Costs in Baltimore

Baltimore is in a higher-cost region — the Northeast and West Coast typically run 20–40% above the national baseline, so expect the upper end of these ranges.

Trap / interceptor sizeTypical cost per service
Small trap (under 50 gal)$115 – $240
Medium trap (50–500 gal)$150 – $475
Large interceptor (500–1,500 gal)$400 – $1,200
Large interceptor (1,500+ gal)$475 – $2,500

Typical ranges per service — your price depends on trap size, accessibility, and frequency. Recurring contracts usually run 15–30% below one-off rates. Estimate yours with the cost estimator or see the full pricing guide.

How Often You Must Clean It in Baltimore

At least every 90 days; also required whenever FOG and solids reach 25% of trap capacity (under Baltimore City FOG Manual (2016)). The industry-standard 25% rule applies either way: clean before fats, oils, and grease reach a quarter of your trap's capacity, because past that point grease passes straight through to the sewer. High-volume kitchens (fryers, BBQ, seafood) often need service more often than the minimum.
