Quick answer: Water droplets on the room-side glass often mean moist indoor air is meeting a cold surface. Start by locating the moisture and reducing its source, not by ordering replacement windows.
Check which surface is wet. Water on the inside face of the glass is different from fog trapped between the panes of a sealed glazing unit. Persistent damp on nearby walls may have another cause, such as rain or a plumbing leak.
Cooking, showering, drying clothes and breathing add moisture to indoor air. When that air meets colder glass, water can condense into droplets. Low airflow and cold areas can make damp more persistent. A brief patch that clears is not the same as recurring wet surfaces or mould.
These principles apply to aluminium-framed windows too. The frame material alone does not tell you why a particular room is damp. Installation, glazing, weather, moisture sources and ventilation all matter.
A clean soft cloth and a short written record are enough for the first checks. You do not need a new chemical cleaner to diagnose condensation. For ordinary streaks after the glass is dry, see our safe glass-cleaning routine.
Get help for persistent damp, mould, leaks, damaged window fittings or moisture between sealed panes. If you rent, document the problem and contact your landlord or property manager. Do not attempt structural, electrical or elevated repairs yourself. Damp and mould deserve prompt attention, especially where vulnerable people live.
No. First establish where the moisture is and whether ventilation, indoor moisture or a leak is involved. A glazing assessment is useful for fog within a sealed unit.
Wiping removes the water you can reach. It does not remove the source of moisture or solve a ventilation or leak problem.
