Living rooms can show condensation on external walls, rain penetration around exposed elevations, or chimney and roof-related staining depending on position and construction.
These patterns are useful starting points, not diagnoses on their own.
Rain-linked patches should be investigated externally before spending on ventilation products.
Living rooms can combine cold external walls, chimneys, blocked fireplaces, furniture and rain-exposed elevations.
Check external wall exposure, chimney breasts, furniture clearance, window condensation and whether staining tracks rainfall.
Compare the symptom with rain, showers, cooking, laundry, overnight occupancy and heating. The room tells you where to investigate; it does not prove the cause.
Start with what changes in this room before jumping to a whole-house diagnosis.
