Hey, first time poster and D.I.Y. enthusiast here. Searching the internet for ever can only give you so much... it was time to ask a pro or someone who know's what they're talking about. Does anyone know what the piece of wood under the ends of the hallway joists in these photos is doing and what would be the best, long term, belt and braces approach be to rectifying this without further wrecking the hall? It's completely rotted out hence my removal of the sections seen with incredible ease (Like breaking a bourbon in half or less). What should I do? The affected area is a doorway leading from the hall (Original House 1900 ish Stone Wall) to the kitchen (1990's Extension Breeze Block) and below is what I hope is a lintel supported doorway in the basement (Photo Attached), which hopefully would explain why the doorway is smaller than the rest. These houses were apparently built using wood from the shipyard in our Town. I was thinking to... Jack up the ceiling below, Remove all rot and treat with Cuprinol or something ****ing Awesome Use the 3mm Mesh I have and steel wire tie it to the same length of the unknown piece of wood Seat it middle depth between joist and wall arch on slate packing Seal the joist ends with damp proof course to stop concrete bonding Shutter and concrete All advice is appreciated, Can anyone help me :/
