“They kept fifteen hundred for a floor that looked fine to us,” the event manager said. The floor did look fine in the middle. What the landlord photographed was a 40 mm band along the skirting where the finish had lifted, a white tide mark around a floor socket, and rust blooms on the brass door plate forty centimetres from where the snow had stopped. None of it was visible from standing height, and all of it was obvious from a kneeling position with a torch.
Snow builds rarely damage the area everyone is watching. They damage the edges, the fixings and the hidden surfaces, and the inspection at handover is conducted by somebody whose job is to find exactly those things. Knowing the list in advance turns an unpredictable deduction into a maintenance task you can price.
Floor seams and joints, because moisture wicks into the gap and swells the core of engineered timber and laminate. The bottom 50 mm of skirting and wall, because that is where meltwater sits when the snow is piled against it. Metal fixings within a metre: sockets, plates, grilles, door furniture, all of which show rust within days if they are brass or mild steel.
Drains, because polymer gel silts traps and a blocked gully is a call-out charge. Lift thresholds and service corridors, which are on the route the crew used and are always inspected. And the waste: bags, offcuts of protection board, and the swept-up pile that somebody left behind a curtain.
The single most effective protection is a photographic survey on the morning of the build, before anything is laid. Wide shots of each wall, close-ups of every seam, every metal fitting, every existing mark. Timestamped, and if possible signed by the venue’s duty manager.
That survey does two things. It proves what was already there, which is the whole argument in a deposit dispute. And it forces you to look at the space properly before you cover it, which is when you notice the missing sealant along the skirting that will let water in.
A polythene sheet taped 100 mm up the skirting, with the tape on a low-tack backing, costs a few pounds for a whole room and prevents the most common deduction. Closed-cell foam under the snow where the floor is soft or the build is long. A drip tray or absorbent sock around any floor socket. A protective board over any threshold the barrow crosses.
Counterintuitively, the cheap blue tarpaulin is often the wrong choice for a long build. It traps moisture underneath and produces condensation rings that look exactly like water damage, because they are. A breathable membrane or a simple polythene sheet with the edges left loose is better, since it lets the floor underneath dry.
Take a moisture reading before and after if the floor is timber. A cheap pin meter costs less than a takeaway and gives you a number that settles an argument: 12 percent before, 12 percent after, no damage. Without it, a landlord who has decided the floor feels different has nothing to argue against but your opinion, and the deposit is his to hold while you argue.
At strike, do a joint walk with the duty manager, with the survey photographs on a tablet. Fix the small things on the spot: wipe the brass, clear the gully, touch up the skirting with a matching filler. It takes an hour and it changes the tone of the conversation from claim to handover. Bring the survey prints as well as the files, because a duty manager who is handed a photograph of the mark he is pointing at tends to stop pointing.
Add the survey and the joint walk to the job template. Both are free, and together they are worth more than any insurance policy on a venue job. The snow powder for events is designed to drain cleanly, but no material can protect a floor from a build that was never surveyed.
