    Venting an orphan chimney breast

    Hi all. I live in a house with 3 floors. The previous owners of our house removed a chimney breast in the loft (floor 3), and they also removed the chimney stack from the roof. However, on the lower floors (1 and 2) they left the rest of the chimney breast standing. This means we have a chimney...

    Sewer Vent?

    Hi folks, anyone know what this is - it’s made of cast iron? There’s one at the boundary of a lot of properties in Aberdeen.(which all seem to have been built in the mid 1960s). I think it might be a sewer vent but would like confirmation as we’re widening the opening to our driveway. Thanks

    Cladding, vent, gap... what thickness battens to use

    I read a few different views on the thickness of the battens to use for attaching cladding to a solid brick built building. I was under the impression that 25x50 roofing lats are the norm, but the last couple of posts I've read say the battens should be 2 or 2.5 the thickness of the cladding...

    Can I vent a disused fireplace through suspended floor?

    Hi, I know old fireplace/hearth questions are talked about on here a lot but i don't think this question has been answered, or if it has, not comprehensively. I have taken out the concrete hearth of an old disused fireplace, in preparation to re-lay the original t&g flooring throughout the...

    Blocked off Chimneys on Party Wall (Leave, Vent, or... ?)

    So, we have 3 chimney breasts that are blocked off and are on the party wall - they are all papered over and I presume plasterboard/wood or similar has been used to block the gap. These are not vented at the bottom, which I thought had to happen. (Please note that I'd prefer not to have a vent...

    Vent in living room, is it needed?

    Hi, I've been renovating my house, and removed the front cover of this vent in my living room, I don't even remember what the front looked like. The vent appears to just be a short pipe but has some channel on the inside so air doesn't just flow straight through the pipe. I have taken this...

    I have a simple question, to which I have been getting conflicting answers: Can I cut a section out of a flat roof joist to run through some ducting? Happy for it to be flat channel. The rafters are 170mm. I've seen some info but think it's about floor boards: I have seen enforcement...

    Air brick inside clothes wardrobe needs filling in -what do I use?

    Hi all, could use some input on this because I'm a bit of a novice and need to make sure I'm using the right tools for the job! Our house was built in the 1940s and we've lived there for almost 30 years, and little did we know there was a badly filled-in air brick inside my build-in clothes...

    Should my bathroom waste be vented?

    Hi I've got a recently built extension with a bathroom. The shower trap is letting sewerage smells come up from it. I've been doing a bit of research and I'm thinking that the issue may be that the soil stack is not vented. The waste from the shower, bath and basin connect to this stack on the...

    Is there any reason to have air vents above floor level ?

    Hi, I’ve got a ground floor flat conversion in a 1900 ish house. There are 3 air vents above floor level about 2 feet up the wall. Those areas seem a bit cooler obviously and maybe causing condensation ? (There was also a higher level one near the ceiling) You can feel a bit of a draft even...

    Smell coming from en-suite...

    Hi, any advice would be greatly appreciated. I've noticed a soil/waste smell coming from the en-suite for a few months. Most of the time it's quite faint but on occasions it can be quite noticeable. I think I've narrowed it down to an open stack pipe which vents directly into the loft above the...
