Saved me some time and effort, ta.

I have an old down lighter above my oven, it's abit old fashioned and takes a screw bulb. I want to replace it because as it's the old type ones (1980 something) it looks naff, and has holes in the top unit for heat to escape, I don't like the steam from cooking going up through the light...

The black on the insulation? Probably just dirt, as various insects or dust is blown up through the vents at the eaves. But check to see if the plasterboard underneath has a vapour control layer (Plastic sheet) or is foil backed, if not then maybe to much moisture is getting through and it...

As per mointainwalker. However it's a little odd to be getting mould in such an area, if you are not getting it elsewhere (I assume as you don't mention it). To get cold bridging from a unheated hallway, but not on external walls is a bit odd, make sure there is no source of damp, leaky...

Download google sketchup (really easy to use, that image took less than a minute). Then just screen print and crop.

As woody says, likely cold bridging, I assume that purple wall is external. Haul yourself into the loft, and see if there is insulation missing there, or if it coincides with a joist/rafter (the stud "could" act as a cold bridge, but more likely there is a gap between the joist and the...

:lol: How could you suggest such a thing! The idea of these membranes when they were developed, was that when condensation formed behind the inside membrane, they would intelligently open their cells up, to allow it to permeate back into the room. The obvious flaw being, that if you do...

You absolutely do need a VCL with foil backed insulation between the studs. I have seen tests where without a VCL, the gaps between the insulation and studs* act as cold bridges, and condensation occurs, though in fairness it is a low amount, it's still not worth it for the cost of a plastic...

In most old houses with double glazing you get cold bridging around the brick surround to the window (the bricks surrounding the window, not the window frame itself), in most cases this is just due to poor installation, particularly in older houses. This is because you have the inner and outer...

You will get condensation on and around your windows due to cold bridging, most double glazed windows are not that good, and in older properties you are prone to cold bridging the brickwork around the window. If you have a 1930s house with cavity wall insulation, I would assume this is post...

My cold tap to the bath has stopped working, it is also very stiff and rotates about 1 turn rather than several. The cold tap in the sink next to it works fine. I had a plumber in, but he said that the taps should be replaced as they are old (6 years approx), and because of the way they...

Ideally the buildup should have been... cladding battens membrane studs = with insulation internal cladding Cladding nearly always leaks, either through butt joints, capalirary action or at corner details. Now your probably going to get someone saying "ah yes, but they build boats...

No cavity, no membrane, pretty much what i would expect to happen. You can lather on sealants and mastics to all the joints, particularly the corners, it may work, but will need ongoing maintenence. Where possible a timber coverplate with drainage grooves will work better than mastic.
