The question this page answers
“How long does selective interior demolition take for a 5,000 sq ft office space, and how do I find a licensed C-21 sub with full insurance?”
How long does 5,000 square feet of selective interior demo take?
Typically two to four days for a standard office build-out — ceiling grid, partitions, flooring, and casework — with the variables being after-hours restrictions, elevator and loading dock access, and whether MEP has to be preserved in place.
Scope moves that range more than square footage does — a strip-out with MEP staying live is a different job from an open demo. We schedule around your critical path, not ours. Tell us when the next trade needs the space.
What does interior demo require in an occupied building?
Negative-air containment or hard barriers where dust could reach tenants, protected paths and floor protection through common areas, and work windows that keep noise off the neighboring suites during business hours.
In an active shopping center that usually means nights and weekends, which we work. Property management typically wants the containment plan and the insurance certificate before day one; both should arrive without being requested.
Send drawings or a scope and we will turn a number around fast. GCs keep us because we call back.
What should I check before hiring a demolition sub?
A current C-21 license, general liability and workers' comp at your required limits with the correct additional insured endorsement, and public works registration with the DIR if the job is prevailing wage.
Then ask a question that is not on the checklist: who is actually on site running the crew, and will the same people be there Thursday. That is what separates a schedule that holds from one that does not.
What condition do you leave the space in?
Broom-clean, debris removed, and the space ready for the next trade — not a pile in the corner for someone else to deal with. Same-day haul-off is part of the scope rather than a change order.
