Mosquito Nets for Balconies, Enclosed to Size

We start by drawing the balcony's openings: the clear height from parapet to slab, the widths between columns, and the position of anything that must stay reachable — an AC outdoor unit, a tap, a plant ledge, a window to be cleaned. Fixed panels fill most of the space; access panels go where you need to reach out.

Large openings are divided by vertical mullions and sometimes a horizontal rail, so that no panel is so large it drums in the wind or bows inward. Panels line up with existing columns and railings where possible, so the enclosure looks like part of the building rather than an addition.

Standard fibreglass mosquito mesh is fine on a window, but a cat's claws go through it quickly, and a cat leaning on it can push it out of its frame. For a cat enclosure we use a pet-resistant mesh, which is several times thicker and resists tearing, held in frames with a secure spline and no gaps at the edges, especially at the bottom where cats test first.

Bird-proofing is mostly about leaving no landing gap. Pigeons will use any opening a hand's width wide, so the enclosure must meet the slab, the walls and the floor fully. Gaps around pipes and AC brackets are closed with fitted mesh pieces.

During the monsoon, balconies on exposed elevations face strong onshore winds and horizontal rain. Panels are fixed with stainless anchors into concrete or solid masonry, never into plaster alone. Frames are a heavier section than window screens, and mesh is chosen to resist corrosion: polyester or coated fibreglass, or stainless near the sea.

Rain will pass through mesh, so the balcony's own drainage must stay clear. We keep the bottom of the enclosure clear of the floor drain and avoid ledges that trap water. Salt deposits are rinsed off with fresh water every few weeks on sea-facing balconies.

In apartment buildings, balconies are part of the building's elevation, and many housing societies set rules on what can be added. A slim frame in a colour matched to the railings or window frames, with dark mesh, is the least visible addition and is usually acceptable. Check before work starts, and we can provide a drawing for approval.

To see how fixed and sliding panels might combine across a balcony opening, the mosquito net chooser on this page is a useful starting point before the visit.
