I obviously need to talk to my local building inspector on Monday but wonder if anyone can help me out here - I have a 1930's solid concrete block house, and have started to lift a few floorboards to see what is underneath - seems the timber joists (100x75)just sit on the concrete sleeper walls at either end with no sort of fixing used. There are 2 more sleeper walls across the 3.5m span of the joists.
I am hoping to fit insulation between the joists but am wondering if I need to be looking at fitting joist hangers or is it going to be ok just to leave them as they are - after 80-odd years the floor is level, has minimal bounce and no signs of damp or anything else so would hope I can just leave it as is but I fear the inspector may disagree - anyone got any knowledge that may put my mind at rest ?
