  • We have a laundry "room" (glamorised cupboard) within the loft conversion of our house. There's a washer and separate dryer in there, and little other space due to reduced head height within the eaves. A big part of this space was taken up by a cold water tank for an unvented heating and hot water system, which was in an uninsulated cupboard-within-a-cupboard.

    I've just had the whole heating system replaced with a vented system, which involved taking out that huge cold water tank. I can now see that the previous owner had an old school dryer with trunking that took the moisture outsize, via a hole in the exterior wall. I looks like they've taken out a brick or 2.

    I'd like to get rid of that hole in the exterior wall for fairly obvious reasons. Does anyone have any smart ideas the best way to get that plugged quickly from the inside? I don't want to get up on a huge ladder to address it from the outside. I also don't want to just wait until I can arrange and afford a builder to properly repair it with bricks and mortar due to it being bloody cold right now.

  • A photo would help. But personally if it's just a small brick hole I'd fill it with expanding foam. I'd properly get a bin bagpush that into the hole somewhat cut to size, then fill into the bin bag. But mixing mortar and shoving a brick in isn't hard, and no one will see th ebad job if it's up high.

  • Sorry, that would have helped, wouldn't it!

    On zooming I can see that it's not just a brick out. It's actually been cut out. So correct fix is remove what looks like 2 bricks and then mortar them in.

    Also in the plan is to knock out the stud wall to the right, and then build a new insulated stud wall to the left, to bring all of this void into the thermal envelope.

    I think your idea of bin bag or similar filled up with expanding foam could be a good idea. It'll very quickly fill the hole to prevent drafts for right now, and then be easily taken out later when I want to do the right fix. Thank you!

    It's an old house with lime mortar, and I've got some pointing work to do elsewhere. I've told myself it's a job for the spring once the weather is better, though. I'll probably do this at the same time.
