Ask any Edmonton general contractor where commercial renovation schedules go to die, and demo week comes up fast. It's the first trade on site, which means every day it slips pushes everything behind it — framing, mechanical, electrical, finishing. And because demo is often treated as the "easy" trade, it's where corners get cut and schedules get burned.
Why demo delays are different
A late finishing trade costs you days at the end of a project, when there's sometimes float to absorb it. A late demo sub costs you days at the start, when every downstream trade is already booked. Reschedule the framer and you might lose two weeks waiting for their next opening. The cheapest demo quote that slips a week is the most expensive line item on the job.
The four failure modes
- No-shows and slow starts. Crews that overbook and triage whoever shouts loudest. Your project waits.
- Incomplete teardown. Walls "mostly" out, slab edges left ragged, fasteners in the deck — and your framer burns a day finishing the demo sub's work at carpenter rates.
- Debris on site. If hauling is a separate arrangement, the pile sits there blocking your trades and your inspector's good mood.
- Paperwork gaps. Missing WCB clearance or insurance certificates can stop a commercial site cold — and it's your name on the prime contract.
What to demand from a demo sub
Fixed mobilization dates in writing. One quote that includes hauling and disposal. Insurance and WCB documentation before day one, not after you ask twice. Protection standards for occupied buildings — barriers, debris routes, after-hours capability for strip-outs in operating properties. And a final-walkthrough standard: broom-clean, trade-ready, signed off.
How we run it
Zebra Demolition runs demo like a schedule-critical trade, because it is one. We scope on site with the GC, lock dates, sequence teardowns and selective demo around your milestones, and haul as we go so the site is genuinely ready at handover. Repeat contractor clients get priority scheduling and a dedicated contact — because the second job shouldn't start with re-explaining the first.
Got a project where the demo schedule actually matters? Book a site walk and we'll give you dates you can build a critical path on.
