That is a very good question. The first year of service we had lots of issue getting the yard back in shape. Now that we are in the second year the efforts made by your company have really worked and we are now very pleased.
The specialists who come to service my yard never bother me and always leave a "memo" of the service they performed on my door. I also receive an automated call the day before the service date to inform me that a specialist will be spraying my yard the next day.
