Not everyone has the money for that.. id say the OP aint looking at spending that type of money either. .
I was replying to "seek" who couldn't understand how parts + labour could come to ten grand
I know - that is why I suggested it as a proviso not a rule of thumb - you seem to be agreeing with me yet disagreeing with me?Also if you find a local joiner with a good rep you should be ok. Only idiots normally get the wool pulled over their eyes by a builder doing a runner. Not all tradesmen with their own company want to take your money and run.. A fair amount want to build up a good rep and name.
I can assure you, however, it's not JUST idiots who get taken for a ride - there are a lot of very clever rogues out there who are good enough to pull the wool over anybodys eyes. It happens all the time - showrooms too I might say to add balance.
