I am sorry to hear of Andrea's poor experience, however, I have been a customer of Lawn Jox for three years and felt it was important to respond, simply to confirm that in my experience, if the mowers damage your property they are very happy to work with you on the matter.
The first year they mowed for me, they accidentally broke my front glass door, due to a rock thrown up from the mower. Not only did they offer to replace the door, but they came to my property and offered to sweep up the broken glass. When the replacement door arrived, they came to the property and installed it for me.
I have also never had problems with the quality of the mowing or edging.
