103K: Bungalow mould condensation considering insulation
Insulation is not alternative to ventilation. Bungalows are vulnerable to condensation & mould because of the increased external surface area
Insulation is not alternative to ventilation. Bungalows are vulnerable to condensation & mould because of the increased external surface area
Two damp issues; (1) rain from chimney, flaunching, roof leak (2) vapour, mould, condensation from: extractor fan (fixed) kitchen & fish tank
Leak neighbour side; obsolete heat pipes buried in rear extension and poor ventilation/ heat. Hygroscopic salts on two first floor chimneys.
RICS nor PCA teach surveyors to test damp; holistically, using a root cause approach, based on evidence, against British Geological Survey
The owner wanted to fix suspect Ring Damp, with plenty of time, before considering putting the property on the market for sale.
Damp survey to determine if there are major damp issues before instructing a RICS homebuyer survey. Mould & condensation from poor ventilation.
Mouldy second floor Victorian purpose built flat. Flat roof is suspected of leaking. Landlord improved ventilation dampness, mould continues
Mould growing in a recently refurbished modern church conversion – washing machine waste was leaking.
Use a metal detector to uncover condensation risks, such as RSJ, lintel, eletrics, metal pipe.
Use Infra-red to highlight: heat loss gain, missing insulation, condensation mould risk, lack of heat loss points to hygroscopic salts.
