(Hard to give a cost as he does both major and minor tree work.)
Our house is cooled by two huge silver maples which should have split and perished years ago. Bob has carefully preserved them on a bi-annual basis. He really knows his trees, is sensitive to the property they are on, and his fees are comparable. I trust him for all my many trees, as he always gives good advice. He's punctual and does a perfect clean up. And he keeps in touch to remind me of necessary, planned work.
