Project story
One large warehouse, split into two separate units
The owner of a warehouse in Delta's Tilbury industrial area wanted to turn one large unit into two separate warehouses. The space still had an old steel structure and a storage mezzanine, and there was nothing dividing the floor.
QUAY demolished the steel beams and the mezzanine they carried, recycled the steel and disposed of the rest, then built a new demising wall to separate the two units. The wall is 50 feet long and 22 feet high, framed in steel studs, filled with insulation, and finished with drywall on both sides, taped, mudded and sanded ready for paint. A final clean left both units empty and ready for their next use.
Demolition took a few days in late April 2025, the wall was framed and boarded over the next two weeks, and the work was complete by mid-May, in line with the three-week schedule in our proposal.
What we did
- Steel beams and storage mezzanine demolished
- Steel recycled, debris disposed of
- 50' x 22' demising wall framed in steel studs
- Insulation through the full wall
- 1/2" drywall on both sides
- Taped, mudded and sanded ready for paint
- Final clean-up and disposal
Engineering, permits and painting were outside our scope on this project.
The finished units
Two clean, open warehouses
With the mezzanine and old steel gone, each unit has a clear floor from the front office to the loading door. The new demising wall runs the full 22-foot height, so the two units are clearly separated, and the insulation helps keep sound and temperature from carrying between them.
Before and during construction
From mezzanine to demising wall in three weeks
Before the work, the warehouse held a steel-framed storage mezzanine with stairs, guard rails and wood decking, plus loose steel columns and beams across the floor. The crew took the mezzanine apart in sections, separated the steel for recycling and cleared the floor.
The demising wall was then laid out and framed in steel studs to the full 22-foot height using lifts, insulated, and boarded with drywall on both sides. Once the joints were taped, mudded and sanded, the site was cleaned and handed back.
- Late April 2025: mezzanine and steel demolition
- End of April: steel stud framing
- Early May: insulation and drywall
- Mid-May: taping, mudding and final clean
- One project manager from start to handover

Demising and unit splits for property owners
Splitting a large unit can make it easier to lease and bring in more rent. The work is usually fast but needs care: heavy demolition, tall framing, and a wall that properly separates two tenants.

FAQ
Warehouse demising wall questions
Common questions from owners planning to split or clear out a warehouse.
How much did this warehouse demising project cost?
The work fell in the $30,000 to $40,000 range before GST. That covered demolishing the steel beams and mezzanine with recycling and disposal, and building a 50 by 22 foot insulated steel stud demising wall with drywall on both sides, taped and sanded.
How long did it take?
About three weeks: a few days of demolition in late April 2025, then framing, insulation and drywall, with the work complete by mid-May.
What is a demising wall?
A demising wall separates two tenant spaces in the same building. In a warehouse it usually runs from the floor to the roof structure so each unit is fully closed off from the other.
Do I need a permit or fire separation for a demising wall?
Often, yes. Depending on the building and how the units will be used, a demising wall may need to be a rated fire separation and may require drawings and a building permit. On this project engineering, permits and fire-stopping were handled outside our scope, so QUAY reviews those requirements with each owner before pricing.
Can you remove a mezzanine?
Yes. QUAY removes steel and wood mezzanines, stairs and racking, recycles the steel where possible and leaves a clear floor ready for the next use.
