A commercial fire is two problems. The first is the building — what is structurally sound, what is contaminated, what has to come out and what goes back. The second is the file — whether the documentation is good enough that the claim moves at the speed of the work instead of the other way round. Owners who get back into their space quickly are usually the ones who handled the second problem properly in the first week.
This guide covers fire damage restoration for commercial and industrial properties in Mississauga and Peel: the sequence, who does what, and what insurers and adjusters consistently ask for. It is educational and general in nature — not legal advice and not insurance advice. Your policy, your adjuster and your own advisors govern your claim.
Sofisa Group Inc. is a commercial general contractor in Mississauga, ON. The service page for this work is fire damage restoration in Mississauga. Our scope after a fire is the construction half: make-safe, strip-out of fire, soot and smoke affected materials, abatement sequencing where older stock requires it, and the rebuild — framing, drywall, ceilings and finishes. Dry-out and extraction after suppression is a specialist restoration trade that we coordinate alongside our work rather than claim as our own.
Stage one: make-safe and board-up
Nothing useful happens until the building is secured and the hazards are understood.
- Access and authority. The fire service releases the building. Until then nobody enters, including us.
- Board-up and weather protection. Openings closed, broken glazing secured, roof penetrations tarped. In a Peel plaza or a Dixie industrial unit this is also what stops a second loss from rain or entry overnight.
- Structural assessment. Where heat reached structure, an engineer's view comes before demolition planning. Partial or structural teardown is a different scope with different approvals — where that applies, our guide to the commercial demolition permit process in Ontario covers the approvals side.
- Utilities. Isolated or restored as appropriate, coordinated with the base building.
- Containment of the affected area. Where the rest of the building is undamaged and still needs to trade, separation goes up early. A fire in one plaza unit does not have to close the whole row.
Photograph everything before any of this is touched. This is the point most claims are won or lost on, and it takes twenty minutes.
Stage two: suppression water and dry-out
Most commercial fires in Mississauga involve as much water as fire. Sprinkler discharge and hose streams travel, and they travel into cavities.
The order matters: wet, contaminated material comes out so cavities can actually dry, drying equipment is placed by the restoration specialist, and readings are held and logged before anything is closed. Closing a wall over a damp stud after a fire gets you a mould scope in the same building a season later, which is a separate claim conversation nobody wants.
We coordinate that drying trade rather than perform it. The full make-safe, strip, dry, verify and rebuild sequence is set out in our guide to commercial water damage restoration in Ontario, and the local version is water damage restoration in Mississauga. Where the water sat long enough that growth started, mould remediation in Mississauga and our guide to mold removal in Mississauga cover that branch.
Stage three: soot and smoke — what comes out and what cleans
Smoke is the part owners underestimate. It travels far beyond the burn area, it is corrosive, and it settles in places that look untouched.
Removal. Porous material that has absorbed smoke generally comes out: drywall, insulation, vapour barrier, ceiling tile, carpet and underlay, acoustic material, affected millwork. Cuts run back past visible damage to sound, uncontaminated substrate. Insulation in particular holds odour indefinitely and is not worth gambling on.
Cleaning. Non-porous surfaces — structure, steel, concrete, ductwork, hard finishes — are usually cleaned rather than replaced, with the method set by the residue type.
Odour. Persistent odour is normally a sign that something absorbent was left in place or that a cavity was not opened. The fix is scope, not fragrance.
Contents. Stock, equipment and fixtures are a separate specialist stream on most commercial claims and are usually handled by a contents restorer working to the adjuster's direction.
The boundary between "clean it" and "take it out" is the single most argued line on a fire file. Our approach is to define it against what we can actually see and test in the opened building and to write it clearly, because a boundary that moves mid-job is a change order, and change orders are what slow claims down.
Stage four: abatement in older Peel stock
Plenty of Dixie, Tomken and Hurontario buildings are old enough that opening a fire-damaged wall turns something up. Where a designated substance survey flags suspect material, that portion is removed as abatement, cleared, and only then does demolition and rebuild continue. It reorders the programme rather than changing who runs it. The scope sits on our asbestos abatement page, and the local version is abatement in Mississauga.
This is one of the more common causes of a fire file stalling, and it is avoidable: the survey question gets asked in week one, not in week four when the crew hits something.
Stage five: rebuild
The reconstruction half is ordinary commercial construction done on an extraordinary schedule. Steel stud framing, drywall, taping, ceilings, doors, hardware, paint and flooring, with mechanical, electrical, plumbing and sprinkler coordinated back in. Where the layout is changing rather than being restored as it was, it becomes a renovation scope — commercial renovation in Mississauga is where that sits.
we handle the strip-out and the rebuild on one contract with one senior supervisor. On a fire file that matters more than on a normal project, because the gap between "remediation finished" and "reconstruction started" is the gap where a building sits empty, a tenant sits out, and business interruption keeps running.
WSIB and insurance documentation are provided to your property manager and adjuster before we mobilise.
What insurers and adjusters actually need
Every adjuster is different, but the requests are remarkably consistent.
Most adjusters on a commercial fire file ask for the same six things: cause and origin notes, a room-by-room inventory of what was affected, a dated photo timeline, water-mitigation logs where sprinklers discharged, a clear split between emergency mitigation and permanent repairs, and third-party reports. In detail:
1. Photographs before anything moves. Wide shots of each affected area, tight shots of damaged material, the burn origin area if identified, and the water path. Dated, unedited, kept in one place.
2. A scope written in line items, not a lump. Make-safe and board-up, strip-out and cleaning, abatement if applicable, drying, and reconstruction each shown separately. Insurers frequently treat these differently, and a blended lump sum invites a request for a breakdown, which costs a week.
3. A clear damage boundary. Room by room, what is being removed and why. "Smoke damage throughout" is not a scope.
4. Third-party documents. Engineer's letters, the designated substance survey, drying logs and readings, clearance letters. Independent paper carries more weight than a contractor's opinion and is worth requesting early.
5. Timeline documentation. Date of loss, when the building was released, when make-safe happened, when drying started and finished. Duration comes up on nearly every file.
6. Change control. Anything discovered after the scope is agreed gets photographed, priced and submitted before it is done wherever possible. This is the difference between a supplement that is approved and one that is disputed.
We are the contractor, not the adjuster. We do not determine coverage and we do not negotiate on your behalf. What we do is produce the documentation an adjuster needs without being chased for it, attend site meetings, and keep the scope legible. On most Mississauga files that alone shortens the programme.
What to send us
The address and unit, the date of the loss, whether the building has been released by the fire service, photographs, your adjuster's or broker's details if a claim is open, whether the space is partly usable and needs to keep trading, and any engineer or survey report you already hold.

Frequently asked questions
What does Sofisa actually do after a fire?
The construction half: make-safe and board-up, strip-out of fire, soot and smoke affected materials, abatement sequencing where a survey requires it, and the rebuild — framing, drywall, ceilings and finishes. Drying and extraction after suppression is a specialist restoration trade we coordinate, and contents restoration is normally a separate stream.
How quickly can you board up a Mississauga building?
Once the fire service has released the building, attendance from our Mississauga base can be arranged locally. Call (647) 963-4310 with the address and what has happened and we will tell you what we can get on site and when.
Why does so much material have to be removed rather than cleaned?
Porous material absorbs smoke and holds odour — drywall, insulation, ceiling tile, carpet and underlay. Non-porous surfaces like structure, steel and hard finishes are generally cleaned. Leaving absorbent material in place is the usual cause of odour that will not go away.
What documentation does an insurer need?
Photographs taken before anything is touched, a line-item scope separating make-safe, strip-out, abatement, drying and reconstruction, a clear room-by-room damage boundary, third-party documents such as engineer letters, surveys, drying logs and clearance letters, and a timeline. We produce our half of that without being chased — but we are the contractor, not the adjuster, and we do not determine coverage.
Can part of the building keep trading?
Often yes. Where the undamaged portion is safe and separable, containment and hoarding isolate the work so a plaza unit, a floor or a warehouse bay can keep operating. It is priced that way from the start.
What if asbestos is found during the strip-out?
That portion is removed as abatement and cleared before further cutting. In pre-1990 Peel stock this is common enough that the survey question should be asked in the first week. It reorders the programme rather than changing who is running it.
Can you do the rebuild too, or only the strip-out?
Both, on one contract with one senior supervisor. That removes the dead time between remediation finishing and reconstruction starting, which on a fire file is usually the most expensive gap in the programme.
