Grease Trap Cleaning in Raleigh, NC: Cost, Rules & Top Companies (2026)
Running a commercial kitchen in Raleigh? Staying on top of grease trap cleaning keeps you out of a sewer backup and compliant with North Carolina's FOG rules. Here's what it costs in Raleigh, how often you're required to clean, the permit and regulation basics, and the local companies that handle it.
What Grease Trap Cleaning Costs in Raleigh
Raleigh prices near the national baseline; dense provider competition across the metro keeps rates competitive.
| Trap / interceptor size | Typical 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 Raleigh
Clean at 25% of capacity — typically every 30–90 days depending on volume (under Raleigh City Code pretreatment requirements). 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.
