    Sub-floor ventilation using fan

    It doesn't feel like there is much air movement in the sub-floor void, even if I put my hand next to the air brick. The airbrick is actually just a grate that is fixed in the render that runs about a foot up from the ground. It also just feels a bit damp in the void. You mention a Radon fan - I...

    Sub-floor ventilation using fan

    Hi All, I am concerned about subfloor ventilation in my Victorian terraced house. The distance between airbricks at the front and back of the house is about 7.5m but there are loads of dwarf walls in between that are not honeycombed. I don't really fancy altering them.

    Old house - undersized joists

    Old house - undersized joists

    I live in an old house, built around 100 years ago. Ripped up some old laminate flooring downstairs because I wanted to replace it, and thought maybe I could try and make the floor more even below because I want a 240-litre aquarium to go in the corner of the room. Is it a suspended timber...
