Dust in high-rise homes
Flats near construction sites and busy roads in Noida Extension get a steady layer of fine dust. It settles into curtains, sofas and carpets, which then release it every time someone sits down or draws the curtains.
Seasonal timing
The two busiest times are before Diwali, when homes get their deep clean, and October–November, when blankets and quilts come out. Book a week or two early in those months.
