Frequently asked questions
What should I do if water is already coming into my home?
Turn off or unplug electronics first, or cut the breaker if you can safely reach it, and if water is rising fast, prioritize getting people to higher ground or outside over saving belongings. In an emergency, don't hesitate to call 119 for help.
Which types of homes face the highest flood risk?
Semi-basement units, low-lying areas, buildings near rivers, and buildings with underground parking are generally known to carry higher flood risk. If you live in one of these, it's worth reviewing your drains and evacuation route with your household before the rainy season starts.
Do flood barriers guarantee my home won't flood?
Flood barriers and water-blocking panels are meant to slow the water down and buy you evacuation time, not guarantee a completely dry home. When rain is severe, moving to safety takes priority over trying to install equipment.
