Premier Pavers subcontracted our asphalt driveway reconstruction to another company. Premier Pavers' owner was very nice and accomodating in making the deal; however, I was dismayed when the subcontractor had told me he brought a certain quantity of gravel sufficient for the job but I had calculated he would have needed twice as much. There is an industry scheme to not deliver enough material in a paving job to save the contractor money. I called Ian, the owner of Premier Pavers. We discussed the problem and I was assured enough gravel was provided. We disputed claims back and forth by email. I asked him to provide receipts for the materials the company had purchased, which he furnished, but the math didn't quite compute. After several weeks of aggravation, we finally gave up with the contest, knowing that the next time we replace our driveway, we will be on site, 100% of the time, monitoring the progress of the work. Be careful. Do your homework to determine exactly how many truckloads of gravel and asphalt should be added for your job and make sure it arrives on the day of work.
