I understand your comments, but this is how it is.
We can cover nearly all of our work and we have used this guy for about 2 years, Two vans are required at two commercial jobs we do for the same company. We couldn't finish one job as we pulled off due to heavy snow, we got him to go back and finish and agreed to pay a full days money as we need to get the job off.
Put it this way if you had a guy working for you and he missed nearly all the windows he had to do then rings up and says job complete, and then you get a call putting a complaint in that all the work that he was supposed to do was not done only the atrium was done what would you do? We asked him and basically he lied then admitted it, he said sorry and it would not happen again. Blue chip jobs are not easy to come by,sorry but the trust has gone. We think we pay well to avoid idiots, how wrong are we.
