Wrightyson…I’m guessing 200m2 of ceilings over 2 floors..I’d charge you £1000 to Tape n joint them alone. Approx. 250m2 pb to Tape n Joint per floor another
£2K, how much DnD? 300m2 possibly..that’ll cost you £7m2 incl adhesive and sticking reveals.. ( windows/doors ) measured over..so I’m at 5100 + cost of boards..this is based on my Tape n Joint prices of 7 years ago on commercial sites with 3k – 10,000m2 of partioning. House bashing was below me..and I’ve never understood why you’ld skim over a perfectly flat surface like plasterboard unless you can’t fix for shit which is the house bashing game..prices are so shit you have to be quick to make any money and the last trades ie..jointer or spread end up trying to make a silk purse out of a sows ear.
Maybe he doesn’t want the job
