Builder Floor Tank Cleaning

In Greater Kailash, most GK-1 and GK-2 builder floors keep their own plastic rooftop tank, and the translucent walls grow algae between the M-block errands. KaamGenie cleans it gently and food-grade. From ₹699.
Greater Kailash covers GK-1’s M/N/S/W/E blocks and GK-2 — premium kothis converted into four-floor builder floors, plus the busy M-block market. Supply is DJB with borewell backup, and each builder floor typically has its own Sintex or plastic overhead tank, with shared underground sumps per plot. Because every floor stores separately in a small plastic tank on the roof, there are many translucent tanks catching light and warmth, and each one grows its own green film unseen above the flat.
KaamGenie cleans the plastic overhead tanks on GK builder floors — draining, wet-vacuuming the slimy sediment, soft jet-washing at a plastic-safe pressure and hand-scrubbing the algae with soft pads rather than wire brushes, then a food-grade sanitising wash. If the shared plot sump needs cleaning too, see our full water tank cleaning in Greater Kailash. This page is specifically about Sintex and plastic tanks.
On a GK builder floor, each flat’s Sintex tank sits on the shared rooftop in open sun. Light passes through the translucent plastic and warms the water, and algae and biofilm thrive on that light and warmth. Because there are several small plastic tanks crowded on one roof, at least some catch direct sun most of the day. A concrete tank would keep its water dark and cooler, but the plastic tanks in GK green up far more quickly.
GK’s borewell backup adds hardness, so scale settles on the plastic floors and around outlets, giving algae a grip. On the top builder floors the tanks are often the least-used and least-watched, so sediment and rooftop dust build up between cleanings. Near the M-block market, where flats double as offices with irregular occupancy, tanks can stand part-full for stretches — and standing warm water in a translucent tank is exactly what turns it green.
No travel charge anywhere in Greater Kailash. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Greater Kailash — and there’s no travel charge to any of them:
“Do you clean Sintex tanks in GK-1 M Block?” Yes. M Block and all the GK-1 blocks, plus GK-2, are on our regular South Delhi rounds. On these builder floors we can clean just your floor’s plastic overhead tank, or coordinate all the floors’ tanks on one roof in a single visit, plus the shared plot sump below if you want it done together.
“What does a 500-1000L Sintex tank cost to clean in Greater Kailash?” A Sintex tank up to 500 litres starts at ₹699 and a standard 1000L is ₹899. Larger tanks cost more by capacity. Since GK builder floors often have four plastic tanks on one roof, we give a bulk rate on four or more, so cleaning the whole building together is cheaper per tank.
“Can you come the same day to Greater Kailash?” Usually yes. GK is central to our routes, so a morning call to 95603 66362 often gets a crew to you the same day. If we cannot, we fix a next-day slot around your building’s DJB supply time so your plastic tank is cleaned and refilled without leaving your floor short of water.
“Why does my GK builder-floor plastic tank go green quickly?” Your Sintex tank shares an open roof and takes direct sun, and light through the translucent wall warms the water and feeds algae. The borewell backup leaves scale for the film to cling to, and if your floor is used as an office with light occupancy, the water stands warm for longer — which speeds the green film up even more.
“Will your cleaning crack or scratch my plastic tank?” No. We set the jet wash to a pressure safe for plastic, so it clears scale and biofilm without gouging the wall, and we scrub with soft pads, never wire brushes. Wire brushes leave scratches that algae settle into faster, so we keep every GK Sintex tank smooth so it stays cleaner longer after we leave.
