I see it all the time, a Landscaping business under bids me on a job. Open the newspaper to see that landscaper sueing the homeowner because he had not had the right kind of insurance when they miscalculated which way the tree would fall. Straight through the house. Get insurance for tree work or stick to mowing grass.http://douglastreeservices.com I provide detailed insurance coverage to all potential customers and advise them to do the same. Specialization is the key, tree removal is a very dangerous undertaken and should not be left too an inexperienced person. I wouldn't let my plumber do my tree, so I certainly wouldn't let my landscaper do it unless he showed me he was certified.
