This of course is nonsense and was Glasgow District Council's way of avoiding its responsibilities. The truth was the house was not properly constructed, was poorly insulated and had no proper heating system. Glasgow Council have for years treated their tenants with contempt. Condensation is often the result of an inadequate heating system allied with a poorly insulated house. Where the outside walls of the house are poorly insulated they will be cold and water will form on them resulting in damage.
Condensation is unacceptable and can be treated.
There is considerable medical literature supporting the notion that damp causes or aggravates asthma, bronchitis, chest problems, chest infections and depression. You should not tolerate yours or your children's health being affected by poor housing conditions. Getting something done The landlord must by law provide you with a warm and dry home which is relatively economic to heat. This may mean gas central heating, double glazing and adequate insulation. If the house is expensive to heat and or damp then you should firstly inform the Landlord.
