Commercial Plumbing FAQ

Do you offer after-hours service to minimize disruption?

Yes. Commercial spaces can't afford downtime during business hours, so we schedule night and weekend service windows for our commercial accounts and handle emergencies 24/7.

Are your technicians certified for backflow testing?

Absolutely. Our lead technicians carry backflow prevention assembly certification, so your annual testing and any required repairs keep you compliant with your local water authority and Ontario Building Code.

Can you work around Ontario Building Code and permit requirements?

We handle permitting and inspections as part of the job. Every install and retrofit is done to the Ontario Building Code and local municipal requirements, and we coordinate directly with inspectors so sign-off is smooth.

Do you service grease traps and interceptors for restaurants?

Yes — installation, certification, cleaning schedules, and emergency clearing. We work with restaurants and commercial kitchens across the GTA to keep drainage compliant and running.

Do you offer preventative maintenance contracts?

We do. A scheduled maintenance plan catches worn valves, slow drains, and aging water heaters before they fail. We tailor the interval to your facility type and traffic, with priority response for contract customers.

What areas do you cover?

We're based in the GTA and serve commercial clients across all of Ontario, including Ontario, the wider GTA, and surrounding regions.
