Ramadan, Eid and the scheduling squeeze
Ramadan changes the rhythm of every trade in the UAE, and pool care is no exception. Crews on reduced legal working hours compress their routes, and most companies shift visits earlier in the day, both for the technicians' sake and because customers generally prefer the work finished well before iftar. If your regular slot is late afternoon, expect it to move; if you have a preference, say so before the month starts rather than negotiating week by week.
The two Eids create a different problem: demand spikes just before them, as households hosting family want the pool spotless, and then supply dips during the holidays themselves as crews take leave. A pre-Eid deep clean is one of the most commonly requested one-off jobs of the year, and the good providers are booked out days ahead. Plan for it the way you would plan a pre-Eid salon appointment.
