Can we keep trading while the building is dried?
Often, in part. Containment, zoning and working around opening hours let unaffected areas stay in use while wet areas are dried behind sheeting. What rules it out is water in the electrical or mechanical plant, contaminated water in a public area, or a loss large enough that the whole floor plate is a work area.
The way to protect trading is to decide the zones early and stick to them, rather than letting the work spread as more wet material is found. That means an honest first survey, including the floors below, because a zone that has to be reopened later costs more than one that was drawn correctly at the start.
Who is responsible when a leak crosses several tenancies?
That depends on the leases and the ownership, and it is not something a restoration crew decides. What a crew can do is establish the facts everyone will argue from: where the water came from, which areas are wet, how wet they are and on what dates, recorded per area.
Get those facts captured before anything is moved or dried, because they cannot be recreated afterwards. Photographs with dates, readings per suite and a note of when the water was stopped are worth more later than anyone's recollection.
What moves the price of commercial water damage work up or down?
Floor area and how many levels are wet, the water category, how much absorbent material and finish has to come out, how long the water sat, access for equipment and power, and whether work has to happen out of hours. The price is set out and approved before any work begins.
Building type matters as much as area. Heavy timber and thick plank floors in a mill conversion need more drying days than carpet tile over a modern slab, and a tenancy fit-out with cabling, partitions and a suspended ceiling takes longer to open and close than an open plate. Out-of-hours working to protect trading adds time rather than changing the method.
How fast can a crew get to a commercial loss?
Calls are answered 24/7 and a crew is sent as soon as one is free. No arrival time is promised, because honest scheduling depends on what else is running, and storms produce many losses at once. What you can do while waiting is stop the water, isolate power to wet areas safely, and start protecting stock.
Having two things ready shortens everything that follows: someone with keys and access to every affected area, and someone who knows where the valves, the riser isolations and the panels are. In a multi-tenant building those are often different people, and finding them at two in the morning is the usual delay.
What about mold, asbestos and old materials in an older building?
Both are sequence questions. The EPA's guidance is that wet materials dried within 24 to 48 hours generally do not grow mold and that porous materials wet longer are generally best removed. In older buildings, if the work will disturb old plaster, pipe insulation or flooring, ask about asbestos rules before anything is cut.
MassDEP requires an asbestos survey before renovation or demolition and ten working days' notice before asbestos-containing material is disturbed, with an emergency provision and waiver number for sudden unplanned events, and the Department of Labor Standards has parallel rules. For a commercial building that is a real part of the programme rather than a footnote, so it belongs in the first day's conversation.
