The hopper, the balcony chute, or the cabinet gap
Cockroaches and a smoke smell during central fogging usually mean the gasket is gone, not that the whole chute stack has failed.
| What you see | Likely cause | What to do first / typical cost |
|---|---|---|
| Rusted kitchen hopper, smell after fogging | Gasket has perished and the frame is open | Standard 304 hopper: S$188 to S$280 |
| Balcony or tongue-type hopper | Opening is larger than a current flush hopper | S$260 to S$380 including the edge patch |
| Condo hopper is an odd size | The rebate was built to a developer drawing | Custom hopper: S$320 to S$520 |
| Roaches behind the sink cabinet | The gap is the backboard, not only the hopper | Sealing add-on: S$120 to S$220 |
2026 rubbish chute bands
The hopper is a wearing part. Replacing it does not hack the kitchen and does not need an HDB renovation permit. The town council still owns the common chute shaft.

Airtight rubbish chute hoppers and cockroach sealing: access and preparation
Airtight rubbish chute hoppers and cockroach sealing is a permit-exempt visit unless the photos show hacking, a new layout, a window replacement, or the household shelter. The hourly and call-out figures, if this page publishes them, are the ones to use. There is no separate fuel surcharge in the handyman rates this site states.
The number of tasks, whether parts are on site, and access decide the time. An HDB service yard, a condo loading bay and a landed roof are not the same approach. Sunday noisy work is refused when the Town Council or MCST forbids it.

|---|---|---|---|
| HDB | Exempt repairs do not need a permit. Hacking does. | Use the condo column if it is not HDB. | Use the landed column if it is not HDB. |
| Condo | Book the lift and the hours before the van arrives. | MCST by-laws sit on top of the task list. | A landed house has no MCST lift. |
| Landed | Name the storey. A roof or a gate is not a flat task. | A condo is not landed. | External work waits for safe weather and a safe ladder. |
