Hello all

I moved into a new (old) home last April and now the winter is very much upon us, we're finding the house pretty chilly to say the least. It's a very old terraced house and listed, so we have the usual problem of poor windows (not double glazed of course).

However, for this thread I'm hoping someone will have ideas on how best to stop all the drafts coming up from the basement. We have old wooden floors on the ground floor with the basement below. The ceiling of the basement has had a plasterboard ceiling put up with insulation between this and the ground floor floorboards, but there are still a lot of drafts coming up which is really not helping matters. What's the best way of sealing this up - we don't want to carpet the floors as doesn't suit the character of the house.

I was thinking of going round the basement and somehow filling the gaps. Taping up all the plasterboard joints was a thought but I'm not sure how long duct tape or similar would stick for given the porous nature of plasterboard and also as it's a (only slightly) damp atmosphere down there. Also the outside edges or the ceiling will be plasterboard to stone wall or brick and again there's an adhesion issue here.

Expanding foam also a thought but on 2/3 mm gaps seems like a huge overkill and also massively messy (I hate the stuff...).

Any thoughts or ideas much appreciated.

Hi,

Only a DIY'er, so feel free to ignore! :)

For the gaps between the boards and the walls, you could try expanding foam tape.
It has been recommended a few times on this forum lately.
Something like:

As for the gaps between the boards, I may go for taping and jointing - tried and tested, and will definitely stop the draughts.

Or, a decent flexible sealant, such as:

I hope that gives you some ideas! :)
