We find quietly sending out gift cards works well. Every woodcare customer is a part of our maintenance program. We give the customer the option to clean their own deck each year or to have us perform the service. We send out reminders to our customers to choose either option. We provide instruction on how to perform the cleaning service. We educate the customer as to the importance of performing maintenance on their deck and how this will add value to their home. Every customer wants to save money, even those that won't complete the services themselves, but by giving them this option, allows the customer to see the integrity your company has, which will in turn bring trust between the customer and our company.
