Damp in the utility windows

[Niall]

Got a slightly heated utility on the side our Georgian house, solid stone walls, flagged floor, single glazed and drafty barn style external door. My fav room thou as it features the original lead piped water pump drirect from a well (doesn't pump water anymore thou)



Issue. Long story short the tumble dryer in there is causing increased condensensation on the single glazed window and that's triggered moss in some of the wood, as the glass Mets the wood. I assume it's dripping down and the slight cavity is catching the water vice running off.



Questions.

Do I dig out treat with something and then putty over?
Would perspex or another basic secondary glazing help or hinder in the longer term? I'm thinking it would improve the temp gradient, or would it just trap wet in a smaller space?

Secondary perspex sheet, magnetic tape. Same approach as discrete secondary glazing for all old windows. It will improve the internal temperature on the perspex face minimising condensation, but the moisture will still be there, it will just find the next cold surface to condense on… Good idea to get some ventilation to remove the moist air.

Generally for period properties a vented tumble dryer rather than a condensing one is the way to go where possible, safely dumping all that warm moist air outside.

Next best would be an extractor fan as close as possible to the dryer, perhaps wired to come on with the dryer?

The upper window pannel has a pulley that turns a wheel on a curved cogged track. So I'll start by getting that working and fit secondary glazing.
