Condensation on the room side of a window is water from indoor air meeting a cold surface. In a Hamilton home that often means drying clothes indoors, showers without enough extract, or rooms that stay closed on damp days. Mist between the panes of a sealed unit is different — that usually means the unit seal has failed.
A survey in winter pays attention to where the moisture sits, whether trickle vents are open or painted shut, and whether the frame itself is cold-bridging. We do not invent climate statistics or building-warrant rules on this page. The surveyor confirms what the property needs: sometimes better ventilation habits, sometimes newdouble glazing, sometimes both.
