New joists not fully pushed into masonry hanger
Anonymous user 28/02/2024 - 3.23 PM
My builder has installed three new joists to repair broken trimming joist. The new joists extend existing joists and run though to masonry hangers installed into old Victorian brick wall. However, he seems to have cut joists a little short as we have a 10mm gap between joist end and back of hanger. The hanger manufacturer permit an absolute gap of 6mm (also in line with NHBC guidance). My builder has dismissed our concerns as he's been doing this type of work for years! Is this fair or should we be concerned?
Are you a tradesperson and able to answer this question?

Yes joist should be seated fully in the hanger not just for load bearing but for move of the joist hanger to hanger.

I normally leave a 2-3mm gap to allow expansion even though joists are sold with a minimum moisture content most are stored outside in racks so it leaves room for expansion if needed
