I had an installer that didnt know what he was doing, cut my siding ends uneven, cut large gaps around my windows and then chipped bricks around my windows. I finally refused this installers work and another more experienced installer took over.
I had to be worked in between his other jobs so it was about 3 months before my siding was installed. When the job was completed they didnt pick up nails and trash. I contacted better business bureau and nothing was done by them.
I tried to recoup damages done to my driveway culvert and house. window world offered me $100.
