Interior & exterior traps
Both under-sink units and larger in-ground interceptors.
Why Grease Traps Need Regular Attention
A grease trap or interceptor catches fats, oils and grease from a commercial kitchen before they reach the sewer line, where they'd otherwise cool, solidify, and cause a backup – on your property's line or, if enough properties neglect it, on the municipal system. Food service properties are generally expected to maintain their grease interceptors on a regular schedule; how often depends on the size of the trap and the volume the kitchen produces, which we can help assess for your property.
Interior vs. Exterior Traps
Interior (Under-Sink) Traps
Smaller units for lower-volume kitchens, needing more frequent cleaning.
Exterior (In-Ground) Interceptors
Larger-capacity units for higher-volume restaurants, serviced less often but more involved.
Left too long, a full grease trap stops working the way it's supposed to – grease passes through into the line instead of being caught, which shows up as a slow kitchen drain, odour near the trap, or a backup at the worst possible time during service. We clean traps on a scheduled basis or as a one-time service, and install new traps or interceptors for a kitchen build-out or renovation.
Signs a Grease Trap Needs Service
Slow Kitchen Drains
Grease building up past capacity and narrowing the line.
Odour Near the Trap
A sign the trap is due for cleaning before it affects drainage.
Overdue for Scheduled Cleaning
Missing the regular interval increases the risk of a mid-service backup.

Grease Trap FAQs
How often should a grease trap be cleaned?
It depends on the trap's size and how much grease your kitchen produces – we can help assess the right interval for your property.
What happens if a grease trap isn't cleaned regularly?
Grease starts passing through into the line instead of being caught, leading to slow drains, odour, and eventually a backup.
Do you install grease traps for new kitchens?
Yes, sized to the kitchen's volume, for both new builds and renovations.
What's the difference between an interior and exterior grease trap?
Interior traps are smaller under-sink units for lower-volume kitchens; exterior interceptors are larger in-ground units for higher-volume restaurants.
