Hello everyone, I was really hoping someone might be able to advise me on what I need to do to fix an issue I've been left with.

Hi all, expertise needed! In the hunt for causes of heat loss, I've just discovered something odd. Our 2007 brick-cavity house has two 9x9" exterior air bricks which have square, terracotta ducting going through both wall 'skins' and butt up roughly to the INTERIOR plasterboard wall. Inside...

I know this has been posted many times before and I have spent time looking at those threads. I'd just like confirmation from those more knowledgeable that what I'm about to do is correct. The builder has left me a shell of a garage and what will be a utility room on the back. The floor levels...

Does anybody have a diagram or drawing showing how the lower corner of a window sill is constructed, and how the DPC and cavity closers join/overlap to form a waterproof joint? I have recessed windows (i.e. they sit in the middle of the wall), and will be making a sub-sill from creasing tiles...

Evening All. I have a 1950's house - standard brick cavity wall. My window frames are fixed in the middle of the wall - i.e. they appear to be screwed into the gap where the cavity is, rather than in either the inner or outer brick leaf. I am about to build an extension, and would like the...
