Start at the Top: Roof and Terrace Inspection
Your roof is the first line of defence against torrential rain. Before the first downpour, thoroughly inspect your roof or terrace for any loose or cracked tiles, and check for gaps in the flashing. The joint where the parapet wall meets the roof slab
is a common weak point that can develop hairline cracks, allowing water to seep in. Cleaning all debris, leaves, and moss is crucial, as blockages prevent water from draining quickly, giving it time to find and enter any weak spots. Applying a fresh coat of waterproofing sealant to these areas before the rains is an inexpensive and highly effective preventive measure.
Waterproof Exterior Walls
Damp patches and peeling paint on interior walls are often caused by moisture seeping through the exterior. Over time, exterior walls develop tiny, almost invisible hairline cracks. During the monsoon, these cracks absorb rainwater, leading to dampness, mould, and structural weakness. The best time to apply a quality waterproof coating is before the monsoon, as these products require a dry surface to bond effectively. Sealing the exterior prevents water penetration and protects both your home's structure and its interior paintwork.
Clear All Drains and Gutters
This is one of the simplest yet most critical tasks. Clogged drains, gutters, and downspouts are a primary cause of waterlogging on terraces and balconies, which can lead to flooding and severe water damage to your home’s foundation and walls. Before the season starts, ensure all drainage outlets are completely clear of leaves, dirt, and any other obstructions. This allows rainwater to flow away from your property quickly and efficiently, preventing build-up that could otherwise force its way inside.
Seal Gaps in Windows and Doors
Wind-driven rain can easily penetrate small gaps around window frames and doors, leading to ruined walls and furniture. Inspect the sealant or caulking around your windows and doors for any signs of wear, cracks, or gaps. Replacing old weatherstripping and applying a fresh line of waterproof silicone sealant is a quick fix that creates a watertight barrier. This not only keeps the water out but also prevents drafts and improves energy efficiency.
Prioritise Electrical Safety
Moisture and electricity are a dangerous combination, and electrical accidents increase significantly during the monsoon. Get a qualified electrician to inspect your home's wiring for any frayed or exposed wires and ensure all outdoor wiring is enclosed in waterproof conduits. It is crucial to have a functional Residual Current Circuit Breaker (RCCB) or Earth Leakage Circuit Breaker (ELCB), which can cut off power in case of a leak to prevent electric shock. Cover all outdoor switches and sockets with weatherproof boxes and never touch electrical fittings with wet hands.
Trim Overhanging Trees
Strong monsoon winds can cause weak branches to break and fall, posing a significant risk to your roof, windows, and overhead power lines. Before the storms arrive, prudently trim any trees and large shrubs that are close to your house. This simple act of maintenance reduces the risk of property damage during a storm and prevents falling leaves from clogging your freshly cleaned gutters.
Protect Furniture and Prevent Pests
The high humidity of the monsoon season can cause wooden furniture to swell and fosters the growth of mould and mildew. If possible, move wooden items away from walls that are prone to dampness. The damp conditions also encourage pests like termites and other insects to seek shelter indoors. Sealing cracks and holes in walls and floors not only prevents water entry but also blocks access for these unwelcome guests.
