hi,
Just moved into a 1970's bungalow. Had a leek in the toilet and had to lift the flooring chipboard to get into the subfloor to mend the leek. I noticed that the floor joist sizes were only 4" x 2" (100mm X 50mm apprx) the joist centres were 15" (375mm apprx). Is this normal or should I be worried? I was expecting to see at least 6" (150mm) joists
Cheers
