Mumbai high-rise residential elevation at dusk
Service Profile · Pigeon Net

The pigeons go. The view stays.

A knotted UV-stable HDPE mesh stretched on a slim aluminium frame. Stops pigeons, crows and sparrows landing on the balcony, the AC ledge or the atrium void — without turning the elevation into something the family is embarrassed by.

Chapter 01 · The Problem

Three answers the building
secretary has already tried.

Every Society in Powai, Andheri and Thane has a pigeon problem. Droppings on the AC outdoor units, nests in the chajja, the lift lobby air smelling faintly of ammonia. The committee has tried three things. None of them worked. The fourth time the topic comes up at the AGM, somebody finally calls a fabricator.

The Society stops sending letters. The AC unit stops needing a quarterly clean. Nobody comments on the elevation.
i.

Plastic clip-on net from the local market

Looks fine for a season. Sags by the second monsoon, splits at the ties by the third, and ends up flapping off the parapet by the fourth.

ii.

Spike strips alone

Stops them perching on the chajja. They simply land on the floor of the balcony below it instead. The droppings just move down a flat.

iii.

Or simply nothing

And the AC outdoor units carry a permanent rim of droppings, the family stops drying clothes outside, and the Society sends warning letters that nobody knows how to action.

iv.

The fourth answer

A knotted UV-stable HDPE mesh on a slim aluminium frame. Almost invisible from inside. Pigeons can't land, can't nest, and the chajja stops being theirs.

Chapter 02 · How it works

Three parts.
One tensioned plane.

01

A slim aluminium frame

A 16 × 45 mm aluminium perimeter, anodised or powder-coated, bolted to the parapet, the slab soffit and the side walls. Sized to match the opening exactly — no gaps the birds can find later.

02

A knotted HDPE mesh

50 × 50 mm aperture for pigeons and crows; 25 × 25 mm for sparrows. UV-stabilised, anti-fungal, charcoal or black so it disappears against the sky from inside the room.

03

A SS 304 cable tension kit

A 3 mm stainless cable runs the perimeter of the mesh, threaded through stainless eye-bolts every 250 mm. Pulled tight at the corners. The mesh sits flat — no sag, no flapping in monsoon wind.

No nylon ties to the railing.
No drilled wall anchors at random.
No exposed knots above the parapet.

When the frame can't go up — historic facade, sea-facing parapet — we anchor only on stainless eye-bolts in pre-approved positions. Reversible, society-friendly, photographable.

Chapter 03 · Material

What it's made of.
Down to the eye-bolt.

Specified for Mumbai monsoon and four years of UV. The mesh is the part most fabricators cut corners on. We don't — there is no point installing a four-year system on a two-year mesh, and the frame outlasts the building.

Knotted HDPE mesh material
Material 01

The mesh — UV-stable HDPE.

High-density polyethylene, knotted (not extruded), UV-stabilised against four years of full Mumbai sun. 50 × 50 mm pigeon-rated as standard; 25 × 25 mm sparrow-rated where the Society also wants smaller birds out. Charcoal — visually quieter than black against an Indian sky.

Aluminium frame profile detail
Material 02

The frame — architectural aluminium.

6063-T6, the same alloy family as our slim-section windows. 16 × 45 mm slim profile when sightlines matter, 27 × 65 mm domal for spans over 4 m or atrium voids. Anodised silver, champagne, black — or powder coat to any RAL.

Stainless steel eye-bolt and cable hardware
Material 03

The hardware — all stainless.

SS 304 eye-bolts at 250 mm centres, SS 304 perimeter tension cable, SS 304 fasteners and turnbuckles. No MS, no zinc-plated, nothing that can rust and stain a freshly painted parapet through the next monsoon.

Chapter 04 · Where it's installed

Real homes.
Real elevations. Real Society contracts.

Apartment balconies in Powai, Andheri, Thane, Bandra and Lower Parel. AC outdoor unit ledges. Society-mandated atrium voids and podium courtyards. Restaurant terraces and hotel light-wells. The CIDCO buildings where the pigeon problem is now an AGM standing item.

Chapter 06 · Benefits

A system the Society approves
and the family forgets exists.

Stops pigeons actually landing.

A 50 × 50 mm aperture is too tight for a pigeon to land in and too small to walk through. The chajja, the AC ledge and the balcony floor are clear inside a week of install — no perch, no nest, no droppings.

Meets the Society pigeon-control mandate.

The standard solution most Mumbai housing societies approve at AGM. Reversible, non-structural, doesn't change the elevation. We provide the secretary with a one-page approval note and the mesh datasheet.

Visible only from extreme angles.

Charcoal HDPE on a slim 16 × 45 anodised frame disappears against the sky from inside the room. From the street, only a guest looking specifically for it will spot it.

Integrates with an Invisible Grill.

On a balcony where child safety and pigeon control are both needed, we run both systems on a single common frame. One install, one fabricator, one elevation read.

Health benefit, not just cosmetic.

Pigeon droppings carry histoplasmosis spores; nesting in the chajja means the spores enter the AC return and the kitchen vent. Closing off the perch eliminates the source — the practical reason the Society finally votes for it.

Four-year UV warranty on the mesh.

UV-stable HDPE, knotted (not extruded), warranted for four years of full Mumbai sun. When the time comes, we re-string a new mesh onto the existing frame in a morning. The aluminium goes nowhere.

Anti-fungal in monsoon.

Mumbai humidity grows mildew on cheap polyester netting within one season. HDPE is hydrophobic and the mesh runs an anti-fungal additive in the polymer — no green spotting after the first monsoon.

Salt-rated for sea-facing flats.

On Worli, Cuffe Parade and Walkeshwar towers, the standard SS 304 perimeter cable upgrades to SS 316 — the same grade used in marine hardware. The system holds up against the salt the way our window systems do.

Designer-direct.

Suraj reads the drawing. No franchise, no call-centre, no rep filtering technical questions. The relationship is the brand.

Chapter 07 · Common questions

The questions a designer
asks before the quote.

Almost always — pigeon nets are the Society-recommended pigeon-control measure across most Mumbai housing societies. We give you a one-page approval note for the secretary, with the mesh datasheet, the frame specification and the reversibility clause clearly stated.
50 × 50 mm pigeon-rated handles the actual problem in 95% of Mumbai apartments — pigeons and crows. 25 × 25 mm sparrow-rated only matters if the Society is also seeing nesting from smaller birds (rare on high floors, common on low-floor courtyards). The smaller mesh costs about 30% more and is slightly more visible from inside.
Not on this system. The HDPE mesh is knotted, not extruded — knotted holds tension; extruded stretches. The perimeter is a 3 mm SS 304 cable on stainless turnbuckles, re-tensionable from outside in five minutes. The cheap clip-on nets sag because they don't have any of these.
Yes — and it's the most common combined spec in our workshop. We run both systems on a single common 16 × 45 perimeter frame: stainless cables for child safety on the inside plane, HDPE mesh for pigeon control on the outside plane. One install, one elevation, one fabricator.
Charcoal mesh on a 50 × 50 mm aperture is the visual equivalent of a fly-screen at three metres distance — present but not announcing itself. From inside the living room, looking at the view, most designers tell us their client never asks where the pigeon net is.
The mesh has a 4-year UV warranty and runs realistically 5–6 years before re-stringing. The aluminium frame and stainless hardware run 15+ years. When the mesh time comes, we open the cable kit, re-string a fresh mesh and re-tension — half a day per balcony. The frame stays.
7–10 working days from drawing approval to install for a single apartment balcony. Society-wide installs (atrium, common corridors, podium) we phase in tower-by-tower, typically 4–6 weeks for a full Society of 200 flats.

If your Society is running a building-wide tender, mention the flat count and the elevation on the WhatsApp — we quote per-flat and per-tower with a clear phasing plan, not as one inflated lump-sum.
