TreeNut - I received my offer as well. I'm not real keen on their allotted amount for "maintenance" on existing trees. You would need to use an arborist and keep records.
FYI - DuPont describes the option of replacing trees 1)through their certified list 2)through my LCO 3)my own choice. #1 & #2 are covered by extended warranty, #3 is not.
Just like michiman, thank you for all the information through this thread. Very informative and helped me make my decision. Private messages have also helped me understand what I needed to do. For me, taking their offer is the best solution but may not be everybody's solution. PM me if you have any questions that I may be able to assist with.
