How to Stop Damp and Mould at Home in Winter in J&K
Winter in Jammu and Srinagar brings closed windows, heaters, wet clothes and less sunlight. Together, these can leave walls damp and cold, and that is where mould likes to grow. Damp walls also feel uncomfortable and can affect the health of children and elders. The good news is that most damp problems can be reduced with simple habits. Some need a professional.
Why damp and mould appear in winter
Most winter damp inside a home is condensation. Warm, moist air from cooking, bathing, drying clothes and breathing hits a cold wall or window and turns into water. The water soaks into plaster and paint, and mould starts to grow in corners, behind furniture and near the ceiling.
This is different from seepage, where water comes in from outside through cracks, a leaking pipe or a damaged roof. Seepage usually shows as a patch that gets bigger after rain, or a stain with a clear edge. Condensation is more likely to appear on the coldest walls, especially north-facing walls and corners with no airflow.
Signs to look for
- Black, green or grey spots on walls, ceilings or behind wardrobes
- A musty smell that stays even after cleaning
- Paint bubbling, peeling or turning chalky
- Wet-looking patches on walls that feel cold to touch
- Water drops on window glass every morning
- Clothes in cupboards that smell damp or have spots
If you see the last two or three signs together, the issue is likely moisture that needs fixing, not just cleaning.
Simple steps you can do yourself
Start with airflow. Open windows for 10 to 15 minutes every morning, even on cold days, so moist air can leave. Keep a small gap in cupboards so air can move behind clothes. Do not push furniture tight against outside walls. Leave a gap of a few inches so air can reach the wall.
Reduce moisture at the source. Cover pots while cooking and run the kitchen chimney. In the bathroom, switch on the exhaust fan or open a window during and after a bath. Try to dry clothes outside or in a well-ventilated room, not in a closed bedroom with the heater on.
Keep the house warm but not overheated. Even, steady warmth on walls helps reduce condensation more than short bursts of heat. Use a dehumidifier only if it is safe to plug in, and never near water.
Wipe off condensation from windows and sills with a dry cloth each morning. This small step stops water from soaking into the frame and the wall below.
Cleaning small mould patches safely
For small patches on a painted wall, you can clean them yourself. Wear gloves and a mask, keep the window open, and use a mix of water and mild detergent or a cleaner made for mould. Wipe gently, then dry the area well. Do not scrub hard, as this can spread spores.
Never mix bleach with other cleaning products, especially those with ammonia or acid, because the fumes can be dangerous. After cleaning, let the wall dry fully before painting. If the mould keeps coming back in the same place, the cleaning alone will not solve it.
When to call a professional
Call a professional if the damp area is large, keeps returning, or is near a pipe, bathroom, terrace or outside wall. Water stains that grow after rain can point to a leaking pipe or roof joint, and these need a plumber or a mason, not just a fresh coat of paint. Patches that feel wet inside a wall can also mean seepage that needs proper waterproofing.
If you want to add an exhaust fan or change wiring for a fan, always use a licensed electrician. Do not work with wet switches or open wiring yourself. Ladder work on a high wall or terrace should be left to trained workers. Safety comes first, so if you are unsure, ask someone who knows the job.
After the cause is fixed, a painter can apply an anti-fungal or damp-resistant paint to the affected wall. This works best when the source of moisture has already been dealt with.
Booking a verified professional on Tikdum
If you find damp that needs a plumber, mason, electrician or painter, you can book a verified professional on tikdum.com or in the Tikdum app. Describe the problem clearly, share a few photos if you can, and mention the room and the area of the wall. This helps the professional come prepared. Ask them to explain what they found and what they plan to do before they start work.
Is black mould on walls dangerous?
It can irritate the nose, throat and eyes, and it may trigger breathing problems for people with asthma or allergies. Keep the room ventilated while cleaning, wear a mask and gloves, and get help if the patch is large or keeps returning.
Why do my walls get damp only in winter?
In winter, indoor warm moist air meets cold walls and windows, which causes condensation. Closed windows, drying clothes indoors and cooking without ventilation make it worse.
Can I paint over mould?
Not directly. Clean the area, let it dry completely, and then use a damp-resistant or anti-fungal paint. If the moisture source is still active, the mould will return.
How do I know if it is seepage or condensation?
Condensation usually appears on cold walls and window frames and wipes off with water. Seepage often shows as a stain with a clear edge that grows after rain or near a pipe, and it may need a plumber or mason to check.
