Amman's damp-and-leak season starts before you feel it
From December through February, Amman shifts into its wettest, coldest stretch of the year. Rainfall peaks in January, humidity climbs to around 68%, and cold snaps — sometimes with snow over higher neighbourhoods like Dabouq, Abdoun, and Shafa Badran — push our stone-clad concrete buildings to their limits. The problem is rarely the rain itself. It is the water that finds a weak seal, the warm indoor air that condenses on a cold external wall, and the ventilation we close off to keep the heat in. Together they create the mould, peeling paint, and hidden leaks that fill our maintenance calls every January.
The good news: almost all of it is preventable with an hour or two of checks before the season turns. This is the checklist we use with homeowners across Amman.
Early signs your apartment needs attention
Damp problems announce themselves quietly. Catching them in November or early December costs a fraction of what a full repair costs in February.
On walls and ceilings
- Dark or grey patches in room corners, behind wardrobes, or where an external wall meets the ceiling — classic condensation and thermal-bridge spots.
- Bubbling or flaking paint, or a chalky white bloom of salts pushing through the plaster.
- A persistent musty smell in a closed bedroom or storage room, even when it looks clean.
Around windows and doors
- Water pooling on the inside sill after rain, or beads of condensation on aluminium frames each morning.
- Draughts you can feel with your hand around older single-glazed windows.
- Cracked or shrunken silicone between the frame and the wall.
Plumbing and water
- A damp patch on a ceiling below a bathroom, kitchen, or the rooftop tank.
- An unexplained rise in your water bill, or the sound of running water when every tap is off.
- Rust streaks below the tank or around exposed pipe joints.
The winter maintenance checklist
Roof, drainage, and waterproofing
Most serious winter leaks in Amman start on the roof. Before the first heavy rain:
- Clear roof drains and balcony scuppers of summer dust and leaves so water cannot pond.
- Inspect the waterproofing membrane for cracks, blisters, or lifted edges, especially around the water tank, drains, and parapet walls.
- Check the seal where satellite dishes, solar-heater feet, and pipes penetrate the roof — these are the most common leak points.
A liquid or bituminous re-coat of a problem area is a modest job; renewing the full roof membrane is a bigger investment, but it is the single best defence against recurring leaks.
Windows, doors, and seals
- Renew cracked silicone around window and door frames with a good exterior-grade sealant — a tube costs roughly 2–4 JOD and stops a surprising amount of water and draught.
- Replace worn rubber gaskets on aluminium windows, and fit brush strips under external doors.
- If you have single glazing, heavy curtains and a draught excluder cut both heat loss and condensation until you can upgrade.
Damp, condensation, and mould
Condensation is the damp problem most Amman flats actually have — warm, moist indoor air meeting cold walls. Managing moisture in the home matters as much as any repair:
- Ventilate deliberately: open windows for 10–15 minutes twice a day, and run the bathroom and kitchen extractor for a short burst after showering or cooking.
- Keep furniture a few centimetres off external walls so air can move behind it.
- Treat small mould patches early with a suitable cleaner, then repaint with an anti-mould, moisture-resistant paint rather than covering it and hoping.
- Avoid drying laundry indoors on unheated days without ventilation — it releases litres of water into the air.
Heating and safety
- Service gas and diesel heaters before daily use; check hoses, regulators, and flues.
- Never run an unflued gas or kerosene heater in a sealed room — leave a window ajar for airflow.
- On central-heating systems, bleed the radiators, check the boiler, and confirm your carbon-monoxide and smoke alarms work.
Plumbing and the rooftop tank
- Insulate exposed pipes and the tank feed against the rare hard freeze that can burst them.
- Check the tank lid seals and float valve, and look under sinks for slow drips that worsen in winter.
Do it yourself, or call a professional?
Clearing drains, resealing a window, improving ventilation, and repainting a small patch are all realistic weekend jobs. Call a professional when you see a spreading ceiling stain, mould that keeps returning after cleaning, a leak you cannot trace, or roof waterproofing that has failed — these need proper diagnosis, not another coat of paint over the symptom. A leak-detection or damp-survey visit is inexpensive relative to the water damage it prevents, and it tells you exactly what to fix.
Book the fix before February
The households that sail through an Amman winter are the ones that check in autumn and repair early. If your flat is already showing the signs above, our home maintenance services in Amman cover leak tracing, waterproofing, damp and mould treatment, sealing, and heating repairs — backed by our own workshop. A short inspection now is far cheaper than a ceiling repair in January.
