Victorian house insulation project

Recommended Posts

my first thoughts are 

if its victorian  it is probably solid brick wall --no void ,so it will be lather +plaster and air gap up the back of it

If you justinsulate and do not attend to wal dampnes possibilites insulating it could make all sorts of problems 

 I am guessing you r ground floor beamns are just supported on soil and slate packers --

again dampness possibilites 

seal it all up and no ventialation you will get mould 

I see ground is built hard up to outside wall  and door threshold is nearly ground level 

again another damp possibility 

if you can can you need a nice drainage system around the outer wall to stop dampness going into brick + then into house 

you need some proper inspection to address these possiblities before racing into insulation

Thanks John, damp is a concern. There is a tiled gutter along the ground between the two down pipes, maybe we should extend that. I quizzed the tenants when we looked round it, they reckon it isn’t damp, hopefully our surveyor will agree! I’m hoping that there’s a bit of a gap (just a foot or so) under the floor beams, it sounds pretty hollow.
