Need help. 17th Century house. after taking plasterboard off walls to expose timbers, now have a gap between ceiling and top of wall where timbers meet the ceiling. Gap uneven and ranges from say three fingers wide to minimal gap. There is a timber beam running across the top of wall adjoining the ceiling (or not, thus causing the gap!). The beam is stained dark oak so we need some kind of filler say polysterene type filler as a guess to fill out the gaps and stop 400 years of dirt falling from under the bedroomn floor above!
Any ideas anyone? I cant stand it now after two years trying to work out best way.....
