I arrive have a look around,dirty windows..Great.WORK. Asked questions.Turn up for job and discover paint, a lot of licks and varnish left from sloppy reno work done years before.I did ask if they had windows cleaned before, and yes was the reply.SO i gave a quote to clean windows as i see it, a 5 hour estimate. It took 6,To remove all the excess i came across would have taken 8.I explained the situation to the home owner and they were'nt fussed.BUT I DID SAY I WOULD CLEAN THE WINDOWS... Any words from the experienced would be appreciated.cheers
