Comparing hourly rates instead of total visit cost
An AED 40–50 rate with a materials surcharge and a four-hour minimum can cost more than an AED 60–75 all-inclusive quote. Reprice every quote as total dirhams for your exact scope. The hourly number is a marketing figure, not a price.
Never revisiting a standing booking
Hours creep and rate drift are silent: the four-hour slot set years ago continues after your real need fell, and loyal-customer rates rise above market. Re-check booked hours against actual finish times and current ranges twice a year, then ask your existing vendor to match rather than switching.
Sponsoring full-time help for a part-time need
Comparing a live-in worker's salary against a cleaning package ignores visa fees, mandatory insurance, accommodation, flights and gratuity, which push the true cost to AED 30,000–60,000 a year. Count your genuine weekly hours first; below ten to twelve, on-demand cleaning wins the arithmetic comfortably.
