It is a Pro's discretion on if a property is too wet to service. In order to avoid damage to lawns, you can choose to wait until later on in the day or the next day to service it.
Customers are told their property will be serviced as soon as the property becomes dry enough to complete without sacrificing quality. It is your responsibility to monitor this situation and complete your visits as soon as conditions permit. Weekends are used to catch up on visits delayed by rain.
It is helpful if you notify the office in GroupMe if you plan on completing a visit later on.
