I had a tall - maybe 20-25m Manitoba Maple adjacent to my garage, which grew a huge side branch which was laying on, and ultimately, damaging my garage roof, and was imposing on the concrete block construction of the garage itself.
After obtaining a City of Toronto permit, using Daron's arborist report as evidence, Daron removed the entire tree in two days. This was done by climbing into the tree, roping off sections, and cutting and lowering the sections. No boom truck and cranes, this was all by hand.
Other than the obvious noise of chainsaws, Daron did not annoy or bother the neighbours, despite working in close quarters to several other yards. All wood was either run through a chipper truck or taken away in a trailer.
At the end of the first day and upon conclusion, all wood chips, twigs, debris, leaves, etc., were cleaned up and taken away. No mess at all, even though they could have waited until the end of the second day, they cleaned up everything on the first and second day.
I have nothing but a perfectly flat, low stump left in the yard which I can use to put a planter and grow something more suitable for a smaller yard.
There were pieces from the main trunk that were at least 250 pounds and I estimate that the entire tree was close to a ton and a half of wood, expertly wrangled within a confined yard, by only two people (in case you think an "average" tree is something easy to move around, it isn't).
The city is providing a more suitably small tree in the autumn which I will plant to meet city bylaws, and Daron gave me advice on how to plant it and how to maintain it over time, so it provides a nice canopy but doesn't become a garage damaging monster tree.
All in all, highly recommended. Knowledgeable, timely, technical experts, neat and safety aware.
