Condensation and mould on windows in a Clyde rental
Well sealed new Clyde homes trap moisture. When condensation mould on frames and ceilings fails the Victorian mould and damp standard, and when it does not.
In short: The mould and damp standard covers mould caused by or related to the building. Condensation on windows is often about how a house is ventilated, so the report has to separate building causes from living habits.
Tight houses, wet air
New Clyde homes are built far more airtight than older stock. That keeps heat in, but moisture from showers, cooking and drying clothes has fewer ways out, and in winter it settles on the coldest surface in the room: the window.
Building cause or living habit
The standard asks that rooms are free of mould and damp caused by or related to the building. Mould on a frame in a room with a working fan and openable windows may be a ventilation habit. Mould in a wet room with no fan, or behind a leaking seal, is a building cause.
What we look for
Mould on window frames, reveals and ceiling corners, moisture readings on nearby walls, and whether each wet room has an exhaust fan or window. Where a fan exists, we note where its duct ends if the roof space is safely reachable.
Fixes that last
Duct fans outside, check window seals and drainage holes, and make sure every wet room vents properly. Cleaning alone works only when the cause has gone.
