In January last year I was informed by her indoors that i had to re do our bedroom.....total refurbishment, walls to walls & floor to ceiling including a new bed.
This entailed modifying existing wiring, new ceiling ( plastered), new lights, moving a light switch, hanging a new door on the opposite side of the frame, moving radiator pipework and fitting a new radiator, replacing a good number of broken & damaged floorboards, making and fitting a new Oak threshold, making from scratch all new wardrobes, cabinets and doors and then fitting them, all the painting & decorating including the wallpaper & coving.
The only thing I didnt do myself was fit the grippers, underlay & carpet......I never even considered fitting it and I have always taken on most things myself.
From memory about 3.5m x 5m of Axminster hessian backed carpet and underlay with grippers was £570 + Vat (£684) including the fitting which took 2 blokes about 1 hour to do. They had to cut around all the legs of my cabinets, so it wasnt just a 3.5m x 5m rectangle.
Edit. Chris,... I've just noticed you're in Essex, as am I...
