    Cold internal cavity wall

    I can't be the only person with this situation, as any extended house will presumably have similar: We have a 1980's semi. It has timber framing with brick outer.

    Is there any compound or washer that I can use to re-bed a weeping coil fitting? I can create good access to it & have cleaned it thoroughly but still weeps when tightened. Seems to be seeping out from the flange nut thread area rather than the skirt where I thought most likely. Does...

    Alarm power supply

    Hello, I have an alarm installed in our new (not new build) house. I suspect the way the device is wired into the consumer unit is ill-thought out. It is connected to a 6A terminal which is probably satisfactory, but whoever has installed it has put it on the downstairs lighting circuit -...
