Precision Paving And Seal Coating

We hired Precision Sealcoating to recoat our asphalt driveway. They were supposed to use a gas-powered wire brush to clean all the moss and weeds from the driveway before coating. They cleaned a nice strip along each side about 4" wide and left the moss. They put the coating over top of the moss so it was squished down by the application and covered with the tar-type coating. After the first rain the moss reappeared and now, two weeks later, after three rains our lovely newly coated driveway has patches of bright green moss all over it. The persistent salesman who answered all my calls beforehand, refuses to pick up or return my messages. The 1-800 number just returns to the greeting regardless of which number you select. Do yourself a favour, do your homework and use someone else.
