Draughty old double glazing

Martin_Clift

Hi
New to the forum and I think I placed this post at the end of another thread as well, my apologies for that error.

Anyway.
I need help regarding 'OLD' double glazing. and draughty and damp area.
My window goes right down to the floor and after many years we have noticed damp spots on the curtain lining, so I decided to redecorate and get new carpets. When I pulled the carpet up I found that the floor boards did not go right to the double glazing, some were large enough to get my fingers into. The gap had been covered by the carpet which obviously stopped the draught. The outside of the house is ship-lapped and appears to be sound, I have checked under the lead flashing and that appears to be sound an dry, but the wind and damp is coming in somewhere. The only place I cant check is where the window sits on an outside UPVC ledge where some sort of beading has been used.

1) Should the floor-boards go right up to the window?
2) How do I find and stop the draught and damp?

Do I need the window taken out and re-fitted, or should I replace the said window?

Many thanks
Martin

condensation on the inside pane could be the reason for damp spots . having a draught could have helped that . 1) there shouldn't be spaces big enough to get your fingers in and that makes sense . 2} insulate and cove the space with something . possibly a plastic trim .( will help draughts and possibly damp issue ) pity your new would like to see pics . windows to the floor are common when you think of most French doors etc . theyre old so get some feedback and a price from a local trusted tradesman . they might have the answer
