Typically unless you are running something like a restaurant, you don't need routine drain cleaning. Routine cleanings are recommended when you know you have a problem with a drain such as roots, bellies, or heavy grease build up. For a recurring situations, here at A-1 Sewer and Drain, LLC, we offer every month, quarterly, every 6 month, and yearly services. We keep track of those and contact you when the month hits to set up a time to service your drain needs.
