Builder can't guarantee to fix the problem

I had a Builder (Which - Trusted Traders) round yesterday to give me a quote for the work you’ve recommended to be done. Unfortunately his advice wasn’t what I expected to hear. He doesn’t think one shower a day would cause this level of dampness. He said the work can be done but he couldn’t guarantee it will cure the problem. So I asked him what did he think I should do and he said he didn’t know.
In the meantime I have to check with the Freeholders if he would be allowed to drill the Kitchen wall to install the extractor fan. I still need the Extractor fans fitted, but don’t want to end up with the same problems next winter.
I desperately need your advice.
At your earliest convenience can you please advise me where you think I should go from here?
- It is not just the 1/2L of vapour a day from a shower, but respiration 3/4L, cooking 1/4L and drying clothes 1/2L.
- A shower a day could cause considerable mould and condensation by itself, if there is insufficient ventilation.
- In simple terms; vapour production must be compensated for by ventilation, otherwise you’ll have mould and condensation.
- There would be a risk of mould even if you didn’t shower, because humid air is being trapped behind the curtain and there is insufficient heat by the front door.
- Additionally there are areas of heat loss above the ceiling from poor insolation (which I rearranged).
- What else does he think is causing the mould - I shouldn’t invite the question as I know the answer is; none.
Thanks very much for your quick response.
I will have to try another Builder and see what they have to say.
I will keep you updated.
