I agreed to pay Cory to remove leftover roots from a spruce tree removal and stump grind that was done a couple of years ago. After he left I cleared away all the chips and found that the biggest root of them all was not ground out. Totally missed. The roots that were taken out by Corey were miniscule in comparison. And the root was very visible before grinding started. I tried to remove it myself but could not. I texted Cory and called and left a message multiple times and he did not get back to me. Totally ignored me. I then contacted other tree and stump removal people and had someone come in to remove it. I was charged half of what Cory charged me for twice the work using a much bigger and better and expensive grinder. Cory had the gall to tell me they are more of an arborist (which he is not technically) and not really stump grinders. Then why charge me twice what the other guy charged me if its not work you are good at? Picture of the root that was missed is attached.
