I had no issues with foam pushing out the boards. I drilled all the holes first, about 3-4 inches apart, and just squirted in some foam. It’s guesswork how much but, with other holes predrilled, the foam would come out of one of those if it had to. I found that the corners of the floor were an...

I have plenty of air flow below the tiles on the roof, which is important to prevent condensation. If you have a draft blowing through your spotlights then I guess you don’t have any insulation around them. I think you are supposed to create a box or hood for the lights and insulate around that...

My problem was with the plaster boards not being sealed at the top and bottom. I drilled a load of holes an inch or so from the ceiling and filled with foam. This helped but I then found that there were gaps at the edge of the screed blowing air from below the house! This is mainly an issue in...

Thanks for the reply. I think the drainage will mainly be to the fence line and then to next door as we are above the neighbour that side! We’ve had concrete in the same area already and it didn’t seem to be a problem. We have a soakaway with an aco drain along the back of the house already in...

Hi, I am going to lay a big area of paving slabs in the garden, no vehicle use, and the ground is thick clay with pretty poor drainage. My builder has recommended laying a concrete base with a steel mesh to ensure it doesn’t move with the clay drying out in summer and swelling during wet...

Had the floor latexes today ready for the flooring and could see the draft from the walls drying the latex out! Not even breezy today at all! You can see the light areas on the pic.

I’ve filled so many holes in the last 5 years with very dodgy walls that I’m not bothered by the hole filling really. I had a quick check if I could access the void from above and noticed that there is a 1-2inch gap under the first row of tiles before the Facia board starts. Another issue to...

Already bought some no nonsense foam that I was going to use on the skirting and other holes but can get a proper gun and can if that’ll help do a good job! Anything in particular you suggest or is any gun and foam fine to use? Could get something from amazon or screwfix/toolstation. Thanks!

Hi, may have been 50mm! Can’t remember now. I don’t think anything was taped either but they seemed to be rough for most things. I think I was getting on their nerves by asking them to do everything properly. Ubfortunately I wasn’t aware of the need to make it air tight for dot and dab otherwise...

There is! They put 100mm between and about 25mm across them before plasterboarding. Just can see it in the pics as the board hadn’t be cut round the window in that pic. Definitely there though! However, celotex is not the ideal insulation to prevent drafts as it’ll never be cut to perfection.

This pic shows the kitchen ceiling. You can see the gap left at the top left of the image. No wonder there is a draft! Have a feeling I will have to drill and foam the top of that wall and hope that works!

Thanks for the tip. Useful information and brings up a lot more on the issue. I think I will try to seal the holes behind the plasterboard that I know about (waste pipe through wall, cables coming through insulation at edge of wall/sealing) and see how that goes. If it’s still petty drafts in...

Hi, do you know if the dot and dab had a seal along the top (at least) to prevent any air coming down the walls? Do I need to get the builder to fix this some how before he finishes completely? I have a feeling that won’t go down well if it’s a tough job to repair! Thanks

Hi, thanks for the pics. I agree that this method is much better than the way mine has been done! Any idea how I can fix mine or if I even need to? I could seal around the holes and live with the switches being a bit cooler as not much air gets through them. However, could this potentially cause...

Hi, I am having an single storey extension built out the back of my house and it’s almost finished. However, the cold weather and cold wind has highlighted a potential issue. The walls are dot and dab on insulated cavity walls. The roof it pitched at each side to meet in the middle and has...
