Net first, then the mess the birds left
Spikes and optical gel fail on a sheltered ledge because pigeons land beside them. Mites then walk the casement seal into the bedroom. The ledge needs a mesh that closes the volume, and a wash that removes the nest.
| What you see | Likely cause | What to do first / typical cost |
|---|---|---|
| Droppings on the compressor and the bedroom window | Pigeons are roosting on the open ledge | HDPE netting: S$350 to S$580 |
| Mites, maggots or a smell after rain | The nest and guano are still on the slab | Bio-enzyme wash: S$280 to S$480 |
| The whole service yard is open | A ledge net does not close the yard | Full-height mesh: S$580 to S$980 |

Netting is not a compressor bracket
Ledge netting stays S$350 to S$580 and does not drill the facade. A steel bracket under a compressor is quote on inspection, and facade screws stay refused.
Plan Pigeon netting, spikes and guano cleaning on aircon ledges
Switch the unit off and confirm which rooms are warm or dripping.
Service the filter, the drain and the coil that matches the booking.
Do not promise a gas top-up inside a filter wash.
Run the unit and check the drain leaves the tray.

| Access | HDB | Condo | Landed |
|---|---|---|---|
| Access | HDB ledge work stays inside the approved method. Do not drill the facade for a convenience hook. | MCST ledge rules and a possible permit-to-work. | Landed condensers are easier to reach and still need a safe ladder. |
| Tenancy | A stamped receipt is the document the agent asks for. | The landlord and the MCST may both want the service record. | A landed lease still wants the receipt if the clause names servicing. |
| Dust | After renovation, wash the coil before the last clean. | The same order. Protect the lift if equipment is large. | More than one storey means the condensate drain is checked at each drop. |
- Count the fan-coil units
- Say if water drips or the air is only warm
- Mention a tenancy receipt if you need one
- Say if hacking dust went through the blower
- Note HDB, condo or landed
Frequently Asked Questions
How much is pigeon netting for an HDB aircon ledge?
Heavy-duty UV-stabilised knotted HDPE netting, 19mm to 25mm mesh, is S$350 to S$580. It is tensioned inside the ledge without drilling the facade.
Do plastic bird spikes work on an aircon ledge?
Not on a sheltered ledge. Pigeons land next to the spikes. A closed mesh, plus a bio-enzyme wash at S$280 to S$480 if the nest is active, is the repair that stops mites entering through the window seal.
Can the Town Council reject drilled facade fixings?
Yes. The approved method is a tension frame or brackets inside the ledge boundary. Drilling the external wall is outside this page and is not how we mount the net.
