Water Damage in Aged Care: What the First 48 Hours Should Look Like

Why Water Damage Is Different in Aged Care

In an office, a flood means moving some desks and letting the drying equipment run. In aged care, the wet wing is someone's home, and the someone in question may be living with dementia, using a walker, or unable to be moved without clinical planning. You usually can't decant residents to a hotel, and you can't leave a saturated corridor closed for a fortnight either.

The clinical context raises the stakes on timing. Mould growth can begin within 24 to 72 hours of water exposure, and elderly residents, particularly those with respiratory conditions or weakened immune systems, are among the people least able to tolerate it. A slow response to a wet floor isn't just a flooring problem. It becomes an infection control and air quality problem in a building full of vulnerable people.

The common sources are predictable: flexible hose failures under basins, overflowing baths and toilets, hot water unit failures, blocked kitchen drains, roof leaks in storms, and fire sprinkler activations. Most facilities will deal with several of these over the life of a building. The ones that come through cheaply are the ones with a plan before the water arrives.

Not All Water Is Equal

The industry standard for water damage restoration, IICRC S500, sorts water into three categories, and the category drives every decision that follows.

• Category 1 is clean water from a sanitary source: a burst supply pipe, a failed flexi hose, an overflowing basin. Carpet and underlay soaked by Category 1 water can very often be dried in place and fully recovered if work starts promptly.
• Category 2 is significantly contaminated water: washing machine discharge, an overflowing bath with a resident's bodily fluids, aquarium water. Recovery is still possible for some materials, but sanitisation becomes part of the job and some soft materials are no longer worth saving.
• Category 3 is grossly contaminated water: sewage backflows, toilet overflows containing faeces, and rising floodwater from outside. Carpet and underlay exposed to Category 3 water are removed and replaced. In an aged care setting there is no responsible argument for drying and keeping them.

Category also degrades with time. Clean water that sits in carpet underlay for days, warm and undisturbed, doesn't stay clean. This is another reason the first 48 hours matter more than anything that happens afterwards.

The First 48 Hours, Step by Step

The immediate priorities are the same on every site. Stop the water at its source and isolate power to affected areas if there's any chance water has reached outlets or equipment. Move residents away from wet floors, because saturated carpet and wet vinyl are both serious slip and trip hazards, and cordon the area so nobody wanders back in. Then photograph everything before anything is moved. Your insurer will want evidence of the extent of wetting, and photos taken in the first hour are worth far more than a description written a week later.

From there, extraction beats evaporation. Every litre physically extracted from carpet is a litre that doesn't have to be dried out of it, so professional water extraction as early as possible shortens everything downstream. Proper structural drying then combines air movers and dehumidification, monitored with moisture meters until the floor, underlay, and subfloor read dry on the meter rather than merely feeling dry to the touch. Carpet that feels dry on the surface while the underlay underneath is still wet is exactly how facilities end up with the odour and mould problems that surface weeks later.

Be cautious with anyone who quotes carpet replacement on day one without moisture readings, and equally cautious with anyone who promises everything can be saved regardless of category. The honest answer depends on the water source, the time elapsed, and what the meters say. Documentation matters as much as the drying: a restoration report recording the category of water, the moisture readings over time, and the drying targets achieved is what stands up when the insurer, or an assessor, asks what happened.

Where Flooring Choices Meet Flood Risk

Water events are also worth thinking about at specification time. Sheet vinyl with welded seams and coved skirting contains spills and overflows in the wet areas where they most often start, which is one more reason it belongs in ensuites and bathrooms, as covered in our vinyl flooring guide. Carpet tiles have an underrated advantage after a flood: wet tiles can be lifted, dried flat or replaced individually, without the wall-to-wall replacement a broadloom carpet forces on you. If your facility is choosing between the two, our carpet tiles versus vinyl comparison covers the wider trade-offs.

Premrest's full trading name is Premier Restorations Group, and flood and water damage restoration is a core discipline alongside flooring supply, installation, and cleaning. We work to IICRC S500 for water damage and IICRC S520 where mould remediation is required, with coverage across Australia. If you'd like a restoration partner on file before you need one, the full restoration and commercial flooring service is at premrest.com.au.

The Bottom Line

Water damage in aged care rewards preparation and punishes delay. Know where your isolation valves are, have a restoration contractor's number saved before the flexi hose fails, and treat the first 48 hours as the whole game. Get extraction and drying started early and a Category 1 flood is usually a bad week. Let wet underlay sit while quotes are gathered and the same event becomes replacement flooring, mould remediation, and a wing offline for a month.
