I like to be called the day before the service planned. It gives me time to prepare to have all things ready. i.e. I can mark all sprinkler heads marked so your aeration equipment does not damage my sprinkler heads.
Am generally pleased with overall services. Particularly appreciate not having to be responsible for weed control and fertilizing, etc. I love cutting the grass and playing in the dirt and flowers but like for you to do the rest. thanks.
