Hi, I've lived in my Bisf house for 15 years and in last couple of years have started on insulating the rooms internally (basically one room at a time) and so far done the 3 bedrooms.
This year I'm having the downstairs windows replaced and looking at having the ground floor level re-rendered externally, as a lot of the old render is sandy and coming away. Have been quoted around £3k for both walls using K-rend. Is this about right and is K-rend suitable? They were trying to push to include the external insulation which made it twice the price but my budget won't stretch anywhere near that.
I live in Dronfield, Derbyshire. Thanks in advance
