Water Damage in Common Areas: 6 Cleanup and Prevention Steps for Property Managers

A burst pipe, a sewer backup, a roof leak or a broken washing machine in the laundry room: water damage is one of the situations property managers dread most. And when water reaches the common areas — hallways, lobbies, garages, stairwells — you need to act fast to protect the building, the residents' health and the condo association's budget.

Here are the six steps to follow, from the first discovery to the return to normal.

Step 1: Secure the area first

Safety comes before cleanup. Before sending anyone into the affected area, make sure electricity is shut off if water is near outlets or panels, the water source is identified and stopped if possible, and the area is cordoned off to prevent residents from slipping. A soaked entrance or flooded hallway quickly becomes a fall hazard.

Step 2: Document the damage immediately

Take photos and videos of the affected area before any cleanup: water levels, damaged materials, the visible source of the leak. This documentation is essential for the association's insurance claim. Also note the time of discovery and who was notified.

Step 3: Remove standing water as quickly as possible

The longer water sits, the worse the damage gets. Use a wet vacuum or pump for significant accumulations, move furniture and rugs out of the area, and open doors to encourage air circulation. If the volume exceeds what standard cleaning can absorb, call a specialized restoration company quickly.

Step 4: Clean and disinfect thoroughly

Once the water is removed, wash hard floors with an appropriate cleaning and disinfecting product, extract moisture from carpets with professional equipment, clean baseboards and the bottom of affected walls, and disinfect frequently touched surfaces: door handles, light switches, elevator buttons. In garages and garbage rooms, a full floor wash is often needed.

Step 5: Dry completely to prevent mould

This is the most underestimated step. Run dehumidifiers and fans for several days, check the moisture level of materials if possible, and watch for signs of mould in the weeks that follow: musty odours, stains, discolouration. Mould can appear 24 to 48 hours after water damage.

Step 6: Put a prevention plan in place

Regularly inspect valves, water heaters and exposed pipes in common areas; check the condition of gutters, roof drains and garage sump pits; add at-risk zones (garage, laundry room, basement) to your maintenance team's inspection routine. A maintenance team already circulating through your common areas can keep an eye out: a new moisture stain or unusual odour reported early is always better than an emergency call.

In summary

Act fast, document, remove the water, clean thoroughly, dry completely and prevent the next time: that is the sequence that limits costs and protects your building. When water damage hits the common areas of your buildings, a responsive maintenance team can make all the difference between a minor incident and a costly disaster.
