Doing a major home reno, I have ordered my share of bins. I started using Expert Waste Services Inc. as they were the best priced bin I could find. After two bins, I found someone cheaper - what a mistake! The other company's 'truck kept breaking down' or they were 'too busy'. After two bins and about 40 excuses later, I switched back to Expert Waste and couldn't be happier.
I have ordered about 5 x 40yd bins and 2 x 14yd brick bins from them and they have always been there on time and very accommodating. They seem to have multiple trucks and have never had any excuses - they are very reliable.
Oddly enough - the bins I thought were cheaper (because they were flat rate) actually turned out to be more expensive as they have a max weight in the fine print. Even though Expert Waste Inc. charges by weight - it turned out to be cheaper in all cases.
