Before heavy rain, take a look at your balcony or terrace. A quick check helps spot a problem in time, but defects in the structure and waterproofing must be fixed by a suitable contractor.
Clear leaves from accessible surfaces
Sweep away leaves, soil and other small debris, especially around visible drains and grates. Do not push debris into the drain. Only clean places you can reach safely; do not lean over the railing or step onto the roof.
Keep the path for water clear
Check whether planters, boxes or other obstacles stand in front of the drain. Do not cover drainage or safety openings. If water still pools after removing surface dirt, report the problem. Do not use tools or products in the drain that could damage pipes or seals.
Watch for changes
Look out for new cracks, loose cladding, damaged joints and traces of water under the balcony. Do not pierce or repair waterproofing without a professional inspection. Place planters and objects so that they cannot fall or be blown away.
What to send with your report?
Attach a photo of the wider area and the drain, and say when water pools and whether it only happens in heavy rain. If water leaks into the flat below, also inform the neighbour concerned. For inspecting gutters, roof drains and other dangerously accessible places, contact the building manager.
Report the problem through the Practic portal (opens in a new window).
