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
condensation
103H: Chimney, roof leak and poor ventilation
Two damp issues; (1) rain from chimney, flaunching, roof leak (2) vapour, mould, condensation from: extractor fan (fixed) kitchen & fish tank
103F: Neighbours leak and hygroscopic salts
Leak neighbour side; obsolete heat pipes buried in rear extension and poor ventilation/ heat. Hygroscopic salts on two first floor chimneys.
Damp survey
RICS nor PCA teach surveyors to test damp; holistically, using a root cause approach, based on evidence, against British Geological Survey
102Y: condensation leak
The owner wanted to fix suspect Ring Damp, with plenty of time, before considering putting the property on the market for sale.
102M: top floor; mould condensation; suspected flat roof
Damp survey to determine if there are major damp issues before instructing a RICS homebuyer survey. Mould & condensation from poor ventilation.
102L: mouldy second floor flat, suspected rain water from roof terrace
Mouldy second floor Victorian purpose built flat. Flat roof is suspected of leaking. Landlord improved ventilation dampness, mould continues
102G: church conversion, mould, condensation and leaks
Mould growing in a recently refurbished modern church conversion – washing machine waste was leaking.
Metal detector
Use a metal detector to uncover condensation risks, such as RSJ, lintel, eletrics, metal pipe.
Infra-red camera
Use Infra-red to highlight: heat loss gain, missing insulation, condensation mould risk, lack of heat loss points to hygroscopic salts.
