The minimum service call fee encompasses up to the first half-hour of service. After that, it is per hour for on-site time only (which is pro-rated up to the 15-minute increment, per 15 minutes after the first half-hour).
We do charge for materials, which are determined by what is needed.
New clients, clients we have not serviced in 5 or more years, and clients with payment history problems are typically asked to provide a deposit to show good faith and establish a positive rapport with Heads Up Sprinklers.
