Supply disruptions, haze and dust: what to check before and during the dry months, and what to fix while it is dry.
📍 We serve KL, Selangor & Putrajaya.
Before the dry months, clean the water tank and check its float valve so it can carry the house through a supply disruption; during haze, keep windows shut and rinse the aircon filters more often; after it, clean the dust out of curtains, windows and soft furnishings; and use the dry spell to seal cracks and finish outdoor jobs before the monsoon. ClickBina's guides put a rooftop tank clean at RM150 – RM400 and a regular aircon service at RM60 – RM120 per unit (indicative 2026, Klang Valley).
Most home checklists in Malaysia are built around the monsoon: gutters, roofs and leaks. The dry months bring a different set of problems. Water supply is more likely to be interrupted, the garden suffers, dust builds up, and in some years the haze arrives and every window in the house stays shut for weeks.
ClickBina's garden landscaping guide names two dry seasons for the Klang Valley: January–February and June–August. Haze, when it comes, usually overlaps with the second. This page is the checklist for those months. For the wet-season side, use the seasonal home maintenance checklist.
When the mains supply is interrupted, a landed house keeps running on whatever is in its roof tank. The plumbing rules require that tank for exactly this reason. ClickBina's roof water tank guide sets out the legal minimum and how long a tank really lasts a family:
| Figure | Value | What it means |
|---|---|---|
| Legal minimum, urban house with its own tank | 1,300 litres | One day's demand under the plumbing rules |
| Legal minimum, rural or low-cost house | 800 litres | One day's demand under the plumbing rules |
| Planning figure per person | 150 litres per person per day | A family of four uses about 600 litres a day |
| 1,000 litre tank | About 1.5 days of buffer | For that family of four |
| 2,000 litre tank | About 3 days of buffer | The sensible size for a family terrace if the roof can carry it |
If your house regularly runs dry during disruptions, the tank is probably too small or not filling fully. During a disruption, cut use that can wait: postpone the washing machine, take shorter showers, and do not water the garden from the tank. Store a little drinking water from the kitchen tap, which is fed straight from the main, in clean covered containers, and empty them when supply returns so they do not breed mosquitoes.
A tank full of sediment holds less clean water, and the first water after a disruption often comes back cloudy as the mains are recharged. Cleaning the tank before the dry season means the water you are relying on is clean. The roof water tank guide says most homes clean the tank about once a year.
Check the float valve at the same time. It is the part that stops the inlet when the tank is full; a worn one either overflows all the time, wasting the water you are trying to save, or sticks and stops the tank filling. The same guide puts float valve replacement at every 3–5 years. Look also for cracks, brittle or faded plastic and a rusted stand, because a tank that fails during a disruption leaves you with nothing.
When the haze arrives, the aim is to keep outdoor air out and clean the air inside. Shut windows and doors, close the gaps you can (the bottom of the main door, unused ventilation louvres, the gap round a portable aircon hose) and keep the kitchen hood and bathroom fans off unless needed, since every exhaust fan pulls outside air in through the gaps.
The trade-off is stale air. ClickBina's fresh-air ventilation guide explains that a shut condo gets stuffy and that opening windows should wait for times without haze or peak heat. Air the house briefly when the air outside clears, then shut it again. Keep bedroom doors closed so the room you sleep in stays the cleanest.
Aircon filters catch the dust and some of the fine particles, so they clog much faster during haze. ClickBina's filter cleaning guide treats a home beside a main road or construction as a monthly-filter house; during a haze episode, treat every home that way and rinse the filters more often. A clogged filter cuts cooling and pushes dust onto the coil.
After a long haze, book the regular service you were going to do anyway. If the unit smells musty or the coil is visibly dirty, a chemical wash cleans what got past the filter. ClickBina's aircon servicing cost guide recommends a regular service every 3–6 months. If you use a portable air purifier, change or clean its filter on the maker's schedule; a full filter does nothing.
Haze leaves a fine grey film on everything. Wipe hard surfaces with a damp cloth rather than dusting, which just puts it back in the air. Then do the soft things that hold dust: curtains, sofa, mattress and rugs. ClickBina's curtain cleaning guide notes that curtains facing opened windows take in haze-season dust; steam cleaning them in place is priced per panel.
Windows and grilles collect the most. Wash the glass and the frames, clear the tracks of sliding windows and doors, and wipe every grille bar. ClickBina's window cleaning guide suggests the period after the haze as one of the useful times to book it. For a whole house, a single deep clean after the haze is usually easier than room by room.
A dry spell shows up cracks that are hidden when walls are damp, and it is the right time to seal them. ClickBina's home checklist puts it simply: a hairline crack found in the dry season is a cheap seal, while the same crack found in December is a soaked ceiling. Walk round the outside of the house and look at the external walls, the joint where walls meet columns, the parapet, and the porch and apron slab.
Fine hairline cracks in plaster are usually shrinkage and only need filling and repainting. Cracks that are wide, diagonal, growing, or in a beam, column or slab need a closer look. ClickBina's guide to cracks between walls and columns explains which is which. Mark the ends of any crack with a pencil and the date, and check again in a few weeks.
Exterior work goes better in dry weather. Paint, sealants and waterproofing need dry surfaces and time to cure; ClickBina's exterior repainting guide describes two topcoats of weatherproof paint applied in dry weather. Rain stopping the job halfway is less likely in the dry months, so this is the time to book an exterior repaint, a roof repair or a waterproofing job you have been putting off.
It is also the time to fix what the monsoon will test: re-seal loose roof flashing, clear and check gutters before the year-end rains, and repair the porch or perimeter drain. Doing these in August is far easier than in a November downpour.
Grass and plants suffer first. ClickBina's lawn problems guide lists too little water in dry spells as one of the main causes of brown grass, especially for new turf. Water deeply and less often rather than a little every day, so the roots go down.
Water early in the morning, when less is lost to the sun, as the garden irrigation guide advises, and adjust any timer between the dry season and the monsoon. Mulch beds to hold moisture, move pots into shade, and during a supply disruption leave the garden until the mains are back, rather than draining the house tank.
