Damp Question

Raven_k42

Evening all

I've read through loads of posts relating to domestic damp issues...and based on what I'm reading it seems the recommended route is to first get it inspected and determine the root cause. It's the "usual" mould on an en-suite ceiling...plus we have built-in units in the same bedroom along an adjoining external wall and despite my putting vents along the base (and drilling holes in the wardrobes) we still get that musty smell. Sounds a ventilation issue (we do have an extractor in the en-suite)...but I'd like to know for sure.

My question is...who should I get ?. A builder...an engineer...or a specialist damp company ?. I'd like to know first...and then get someone to address it.

Any ideas greatly appreciated.

Many thanks,
K

It doesn't sound like you have damp at all. You have a badly designed ensuite. It doesn't have a window or even an outside vent. The extractor fan is for smells and doesn't remove steam. How architects have been getting away with this for years amazes me. If you were to fit a humidity fan it would run 24/7

ensuite is probably no insulation overhead in ceiling, it it on an external wall and is the mould is worse along that bit?
Hip roof?

Re the wardrobe issue:
take them out, insulate wall behind and refit, anything else is waste of time and money, defy don't need "or a specialist damp company"

if u look closely at 7502 u will see insulation missing from where ceiling and wall meet.
Mould in 7503 is the result

I see it somewhat differently on two counts: if the fan is strong enough and properly vented: then it will extract the water vapour ( not steam) from the shower: I have a 5" fan in mine.
The usual fans fitted were okay for smells in a canary cage, combined by the use of the crap white flexible hose which was left looped in the attic.
