4 weeks to do underfloor heating and screed in a 6 bedder. You've clearly not looked very hard... I reckon that's 3 days work. 1 day to insulate edge strip and polythene, 1 day to pipe up to manifold and 1 day to screed.Thanks Jake.
I will do, its a 6 bedroom home that I cant find a contractor to do without me moving out for 4 weeks, so Im having to do most of it myself and splitting house into 2 and doing 2 manifolds.
