I have had trees removed and pruned as well as stump grinding done by these guys. They get the job done safely and are reliable - they did what was agreed upon with a reasonable price - however, they did not take care to protect or avoid my existing garden (despite reminders that they were damaging a newly planted garden by dragging branches over it instead of going around). Also, ran over a long row of newly planted flowers with the grinder! Did a great job with the trees and removal - if you use them and are worried about your garden, I'd suggest hanging around to keep an eye on things!
