My wife and I are very happy that White Shark was able to squeeze us in before the winter's first freeze to clean out our eaves. We were late in season (Nov. 21st) phoning them to book an appointment so we were put onto a waiting list (they call it a "floating" appointment). The only improvement is that I would ask that they respond to requests on their website; that is, I left them a message (on the 16th) but had to phone on the 21st to get a reply. Yes, partly my fault for being late in the season and clearly they are successful/busy.
On the afternoon of Dec. 6th, their crew just showed up (i.e. unannounced, which we were told would be the case). They worked quickly and we could see that the 2-man team working hard (i.e. they brought empty yard waste bags with them and left the filled bags with us; the contents were wet and quite heavy, so that made sense they were only half-full).
The bill was less than the quote so that was nice. The payment options are convenient. We were home so paid by cheque. But, we could have paid by credit card on line, whether or not we were home so it's a nice touch that they they simply trust new customers (i.e. I didn't have to leave a credit card number for the estimate).
