We've used Sky High twice now and have been exceedingly happy with their work. First time was for work in the back yard: Removal of a large Caragana, pruning away of a Mayday, and pruning of an overgrown Lilac. Second time was for the removal of a massive Spruce leaning over our house and removal of smaller shrubs in the front yard. Stump grinding was completed both times.
Both times, I got to chat with Linda to book the consultation. There was no phone tag, no getting redirected, no lost messages - the process was clear and immediate, Linda was friendly and responsive. Her sons Wes and Micah were awesome and easy to work with. Quotes were competitive and they were honest about projects that weren't worth my money. They did their work with great care. They had large equipment to speed up the work, but also had the skill and patience to climb trees when needed. Our house and nearby flowers suffered no damage due to their diligence, but they were very upfront about possible, unavoidable damages.
I would recommend these guys in a heartbeat. I don't think you will get better prices or quality of work elsewhere!
