Pre-emptive Checklist to Minimize Flood Damage Around Your Home During the Rainy Season

Check places like drains, verandas, window frames, underground parking lots, electrical outlets, and sewage backups before it rains

When thinking of managing a home during the rainy season, it's easy to focus on humidity and mold, but actual damage can often stem from poor drainage, flooding, leaks, sewage backups, and electrical accidents. Particularly in semi-basement units, low-lying areas, first-floor shops, underground parking lots, and old villas or houses, you should check drainage and electrical safety before the rain comes. This list outlines flood prevention points to check around your home before the rainy season kicks in.

Cleaning Balconies and Rooftop Drains

Clean Veranda and Rooftop Drains

Before the rainy season starts, it's advisable to first check the drains on your veranda, rooftop, yard, and in front of your entrance. If leaves, dirt, hair, or household dust block the drains, water may not drain properly on heavy rain days, leading to indoor flooding. This is especially the case for old villas and commercial buildings where gentle slopes around the drains can lead to leaks from even minor blockages. When cleaning, wear gloves to remove foreign substances and pour a little water to confirm that drainage is flowing well, which can reduce anxiety during the rainy season.

Water Barriers and Flood Panels

Water Barriers and Flood Plates

Water barriers and flood plates help to delay water from rushing into access points that are at risk of flooding. For low spaces like semi-basement homes, first-floor stores, underground parking ramps, and warehouse entrances, it's good to measure dimensions and check installation feasibility before the rains come. Even with products prepared, if nobody knows how to use them, installing them in an emergency can be difficult, so it’s safer for family members or staff to learn the setup process together. Understand that these devices are not just for complete flood prevention but are meant to buy time for evacuations and additional measures.

Checking Window Frames and Exterior Walls for Leaks

Check Window Frame Silicone and Exterior Wall Leaks

Leaks during the rainy season don't just occur from the ceiling. If the silicone around window frames is cracked or if there are fine cracks on the exterior walls, heavy rain and wind can cause water to seep inside. If the wallpaper around the windows peels or if mold stains keep appearing, it might signal a leak rather than just a humidity issue. For high exterior walls or old sashes that are difficult to repair yourself, it's better to request an inspection from the management office or a professional before the rainy season begins. Blocking small gaps in advance can save costs on wallpaper replacement, mold removal, and furniture damage afterward.

Checking for Backflow Prevention in Drains

Check for Sewage Backup Prevention

If the drains in your home seem to drain slowly or if the odors worsen on rainy days, it could indicate a risk of sewage backup during the rainy season. While the drains in your laundry room, bathroom, and veranda may seem fine under normal conditions, if there is a heavy downpour, pressurized sewage lines may cause water or odors to rise. Check the backflow traps and drain covers, and for older buildings, confirm with the management entity whether there are common plumbing issues. If water has already begun to back up, prioritize safety by keeping distance from electrical devices and avoid trying to forcibly open drains.

Vehicle Relocation Guidelines for Underground Parking

Vehicle Movement Guidelines for Underground Parking Lots

Once water starts coming into an underground parking lot, moving vehicles can become difficult. Particularly for low-lying apartment complexes, buildings near rivers, and parking lots heavily reliant on drainage pumps, it's advisable to set movement guidelines in advance when heavy rain is forecasted. Consult management office notifications, local government disaster messages, and river water level information, and if needed, it’s safer to relocate to above ground or higher areas before the rain intensifies. The principle is not to enter an underground parking lot where water has already started to pool for vehicle checks.

Raising the Height of Electrical Outlets and Power Strips

Raising Electrical Outlets and Power Strips

During the rainy season, it's best to avoid situations where water meets electricity. Power strips on the floor, chargers near windows, and electrical products on the veranda can increase the risk of electric shock during leaks or flooding. When a long rain forecast appears, it’s advisable to unplug unused electrical products and place power strips on shelves or walls instead of the floor. Especially in homes where water inflow is possible, such as semi-basements, first floors, and expanded verandas, it’s safer to check the position of electrical wiring and ensure circuit breakers are working beforehand.

Once flood damage occurs, the costs of cleaning, repairs, appliance damage, mold, and unpleasant odors can add up significantly. During heavy rain, it's risky to clean drains or go down to underground spaces, so pre-emptive checks are crucial. Check the drainage flow around your home in advance, avoid forcing entry into dangerous underground areas, and if electrical installations get wet, it's safest to refrain from using them until a professional checks them.
