No matter how much hassle, it is so worth getting the 3+ quotes. Late last year we were getting quotes for painting the outside of the whole site, & all were to a specific spec including the paint maufacturer & colours to be used. One joker quoted a rate per square metre of painting to be done + cost of paint, other quotes ranged from 15.5k tl - 35k tl including paint nuff said. Suffice to say we have now have had the work done & everyone is happy, admittedly there were a few paint splashes left on balconies, but that's a very small price to pay considering the savings made elsewhere.
