The wet season brings heavy rain and high humidity, which can cause problems in a home if not addressed early. Checking a house before the wet season starts helps prevent damage and keeps living spaces comfortable. A systematic approach to inspection and maintenance saves effort and protects the property.
Roof and Gutters
The roof is the first line of defence against rain. Inspect the covering for loose or missing tiles, as water can seep through gaps. Check the flashing around chimneys, vents and skylights for cracks or corrosion. Any break can allow water to enter the walls. Remove debris from gutters and downpipes. A blocked gutter can overflow and damage the foundation.
Clean the gutters thoroughly, then test the downpipes by running water through them. If water backs up, consider installing a splash guard. Ensure the downpipes are angled away from the foundation. Water that runs parallel to the wall can seep into the ground. If the roof has extensive damage, seek a professional roofer to repair or replace the affected sections.
- Check for loose or missing tiles.
- Inspect flashing for cracks.
- Clear gutters and downpipes.
- Test water flow.
- Angle downpipes away from walls.
Windows and Doors
Windows and doors must seal tightly to prevent drafts and moisture ingress. Look for gaps around frames and broken seals. Replace any damaged weather stripping or sealant. A good seal keeps the interior dry and reduces heating costs. Check that all windows open and close smoothly. A stuck window can trap humidity inside.
Inspect door hinges and locks for rust or looseness. Tightening or replacing parts improves security and weatherproofing. Ensure that door sweeps are intact and fit snugly against the threshold. A gap can let water seep under the door.
If any window or door has a major defect, arrange for a qualified tradesperson to repair or replace it.
- Check for gaps and broken seals.
- Replace weather stripping.
- Test window operation.
- Inspect hinges and locks.
- Check door sweeps.
Ventilation and Damp Proofing
Good ventilation reduces mould growth. Check that kitchen and bathroom vents operate correctly and are not blocked. Open windows regularly to allow air circulation, especially in rooms that are prone to dampness.
Inspect the attic or loft space for signs of moisture. Damp insulation can compromise structural integrity.
If condensation is visible on walls or ceilings, consider installing a fan or dehumidifier. Professional advice may be needed for large areas.
- Test kitchen and bathroom vents.
- Open windows for air flow.
- Inspect loft for dampness.
- Install fan or dehumidifier if needed.
Drainage and Soil Management
The ground around the house should slope away from the walls. Check that the perimeter is not level or sloping towards the foundation.
Look for standing water in the garden or near the foundation. Persistent puddles can lead to root rot and foundation damage.
If drainage is inadequate, regrade the soil or install a French drain. This task may require a professional.
- Check ground slope.
- Identify standing water.
- Regrade soil or install French drain.
Electrical Safety
The switchboard is usually located outside or in a hallway cupboard. Inspect the main switch for signs of wear or loose connections.
Check all exposed wiring for frayed or damaged insulation. Damaged wires can cause short circuits.
If any wiring appears compromised, contact a licensed electrician to replace or repair it.
- Inspect main switch.
- Check exposed wiring.
- Call electrician for repairs.
Outdoor Structures and Fencing
Fences and decks can suffer from rot or loose boards. Walk along the perimeter and feel for soft spots.
Look for nails or screws that have loosened. Tighten or replace them to maintain structural stability.
If a fence is heavily damaged, a professional may be required to rebuild or replace sections.
- Walk perimeter for soft spots.
- Tighten loose nails.
- Replace damaged sections if needed.
Household Items and Storage
Store items that are sensitive to moisture, such as books and electronics, in dry areas. Avoid placing them directly on the floor.
Check that storage bins are sealed and not exposed to damp air. Rotting timber or mould can spread quickly.
If mould is present, clean with a suitable solution and dry the area thoroughly. For extensive mould, seek professional remediation.
- Store sensitive items in dry areas.
- Seal storage bins.
- Clean and dry mouldy areas.
A thorough pre-season check protects the home and its occupants from the wet season’s challenges. Taking these steps now means less stress and fewer repairs later.
