unbearably cold room & now mould

Post by daveyjkenny » Thu Jul 11, 2019 7:17 pm

Hi,

We live in a 1970's detached house with an extension (25+ years old). The extension room is a bedroom and in Winter is shockingly cold. I mean really really cold that we can't allow anyone to sleep in there. It has an ensuite and the entire space has two radiators. The walls are cold to touch.

Initially I wanted to ask which kind of company would be best to assess why it's so cold, but today I found some mould that can be wiped away, in one of the corners - about the size of bedside table. I assume this is connected to the cold?

I do know that 2 years ago the former owners renovated the ensuite from some kind of wet room to a separate shower room + sink. Could they have done/not done something that could have unbalanced the air flow perhaps. There are tell tale signs of cavity wall insulation and we definitely have roof insulation. So far, the only idea I have is to have international wall insulation applied, but that was before finding the mould.

Can anyone help please before Winter ruins our home?!

I am NOT an expert but if the room is cold what source of heat is there in the room?
You did mention radiators, but do they work?
If you seal a box the air will condensate eventually, so you need a free flow of air, so what ventilation is there?

Another thing to check is the guttering, is there any? have you looked into it? (Literally)
Fret not, a forum is a collection of opinions. Above, are mine.

Which is correct? Metre or Meter? Click the link to find out more.

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?

thank you for the reply,

Yeah there are two radiators, both of which work fine and are as hot as the other radiators in the house. I was thinking the same about free flowing air but we do have one of the windows open regularly over summer.

haha well our guttering does need some cleaning (nothing major), but where the mould is located is actually near a flat roof which may need looking at. Thank you!
