I have used D&p plastering many times and they are spot on.
Extremely tidy and there plastering is of a good standard at a fair price, I know that he used to have a partner called paul, but Dean himself is spot on.
Try Dan 2802 and his Crew they seem to know everything within the building trade and have even appointed themselves as advisors on the forum for some time now, so I guess you need to contact them for the best advice within this industry.
Good luck
