Some AECS Layout openings look protected from the front but still fail at one side. A utility corner looks clean after washing, then feathers and droppings return near the AC pipe by evening. That is why the active ledge, pipe-side gap, AC pocket, and utility corner matter more than a single width measurement.
AECS Layout homes can have very different bird routes: tower balconies, utility shafts, AC pockets, and glass-front sit-outs. The issue may be a crow on the rail, a myna on the window shade, sparrows entering a pipe-side gap, parakeets landing from a tree, or pigeons joining the same ledge. The work should follow the messy point first, not just the biggest visible opening.
The AECS Layout fit should notice this: EverSafe looks at the AC-side pocket, ledge depth, stain pattern, feather collection, AC bracket side, pipe return, utility corner, wall strength, balcony use, drying path, and cleaning reach. That reading decides whether the net should protect a front face, wrap a return, close a pocket, or leave a serviceable opening.
For AECS Layout, the best result is workable hygiene, the balcony should still breathe, daylight should remain comfortable, clothes should still dry, and the finished line should not look like a rough patch from outside.
Near AECS Layout, this service is kept for mixed bird mess and entry. If the problem is one repeated pigeon nesting route, a pigeon-focused installation may be the better fit, but mixed bird pressure needs broader ledge and entry-point reading.
