Common questions

Are you licensed and insured?

Yes. We are a licensed contractor, registered with WSIB, and we carry $5,000,000 in commercial general liability insurance. Certificates are available on request.

Can you work in occupied or time-sensitive spaces?

Yes. We are often brought in for work that has to happen around people and operations, with controlled site access, careful sequencing and after-hours work where the building needs it.
