Some questions guys,
If I have missed these points in the several posts , please accept my apologies
a) do we know that the initial complaint was leaks, and not condensation b) why was a new roof required, why not re-use existing tiles ? c) has the roof insulation been improved e.g now 200mm from 50mm ? d) has the heating system been changed or upgraded ( And not using paraffin or calor gas stoves ? ) e) have the windows been changed recently f) If Upvc windows, do they have a trickle vent, and are they open g) does the bathroom have an opening window, and mechanical vent h) Is the kitchen likewise vented i) Is there a tumble drier in the property ? j) have any other home improvements been undertaken recently ? k) does water show only during rain, or some time after. ( perhaps on a dry day ??) l) is it always in the same place, or varying positions m) What sort of temperature does Mr Giles keep his home ? n) Are there gas fires in the property, are the air bricks free and not coverd or blocked ? o) Are the chimneys clean and not blocked p) Are the gutters and RWP's claen and running freely
I think that will do for now.
