Commercial cleaning cost
Pricing depends on volume, equipment, line size, after-hours dispatch, and ongoing relationship. Recurring maintenance contracts (quarterly or semi-annual jetting) are usually more cost-effective than emergency-only billing for high-volume kitchens.
What to share when you call
- Property type and operating hours.
- Which fixtures or drains are affected.
- Whether the issue is recurring.
- Cleanout access.
- Whether grease trap service is part of the scope.
- Compliance or maintenance contract status.
Toronto context
Commercial kitchen drains in Toronto restaurants accumulate grease, scale, and food solids faster than residential lines — and a backup during service hours costs the operator more than the cleaning itself. We schedule off-hours, jet on a maintenance interval that matches the actual cooking pattern, and document each visit for health inspection records.
What to confirm before approving cleaning
- Method should match the actual blockage — snake for soft, jet for grease and scale.
- Camera follow-up should be considered for recurring issues.
- Recurring contract pricing should be available for high-volume sites.
Useful info on the call: property type, hours, recurring history, and grease trap status.
Frequently asked questions
How often should restaurant drains be cleaned?
Typically quarterly jetting for high-volume kitchens; semi-annually for moderate volume. Camera inspection annually helps set the right schedule.
Do you do after-hours work?
Yes. Most restaurant and retail commercial cleaning happens overnight to avoid disrupting service.
Should I sign a maintenance contract?
For high-volume kitchens, scheduled jetting on contract is significantly cheaper than emergency-only response. We tailor contracts to the property's actual demand.
Will I need a backflow valve?
Some commercial properties — especially older multi-tenant buildings on combined sewers — benefit from backflow protection. We assess as part of the conversation.
