April openings, weekly summer service through high humidity and algae pressure, and a leaf-heavy fall close define the year. Winter cover checks after storms help protect the work until spring. Mid-May through September, humid through the middle and stretched by heaters on both ends. Winters freeze properly, so a full close remains the standard even in milder Bay-side microclimates.

A full-service visit includes water testing and balancing, skimming, brushing the walls and tile line, vacuuming as needed, emptying skimmer and pump baskets, checking filter pressure and looking over the pump, filter, heater and salt cell. Filter deep-cleans, salt-cell cleaning, algae treatments, tile blasting and repairs are commonly separate line items — ask for the price sheet.
A green-to-clean recovery in Gaithersburg typically runs $300–$600: shock treatments over several visits, brushing, vacuuming to waste and a filter deep-clean ($80–$160).

DIY chemicals typically run $50–$100 a month plus your time and a good test kit; a service adds trained eyes on the equipment every week and catches small leaks, failing seals and filter problems before they become repairs. Many owners split the work — a service handles chemistry and equipment while a robotic cleaner handles the floor between visits.
Most residential routes are month-to-month or season-to-season, but terms vary. Check notice requirements, skipped-visit policies, chemical surcharges, filter-clean fees and how minor parts are billed before enrolling — those details usually matter more than a small difference in the base rate.
