Soft timber at the floor is the tell
A screwdriver that sinks into the jamb at skirting height is rot or termites. Painting over it feeds the next swarm. The wall does not need to come out.

This is a non-hacking replacement. Bedroom partitions and bathroom wall tiles stay. A pest-control chemical treatment, if the colony is active, is booked with the pest company and is not inside these bands.

Rotted door frames and waterproof skirting, without hacking: access and preparation
Rotted door frames and waterproof skirting, without hacking is hardware and carcass work when the kitchen or wardrobe layout stays put. Hinges, runners, a door leaf in the same opening, and a sectional under-sink rebuild do not need an HDB renovation permit. A new layout, a hacked wall, or a moved gas point does.
Brand-matched hardware takes longer to identify than a generic cup hinge. A soft carcass under a leak is a different visit from a dry door that only needs alignment. Condo management may care about noise and disposal of the old board. Landed houses add stair cupboards and taller doors.

Plan Rotted door frames and waterproof skirting, without hacking
Read the stamp before ordering a look-alike hinge or runner.
Protect the floor and empty the cabinet that has to come open.
Replace the failed part. Do not rebuild the kitchen because two doors sag.
Check that doors close, drawers stay on the runner, and overhead flaps stay up.

| Access | HDB | Condo | Landed |
|---|---|---|---|
| Permit | Layout unchanged: no HDB permit. A new kitchen layout is V On Construction. | MCST quiet hours and a lift for sheet material. | No HDB permit. A structural opening is still not carpentry. |
| Board | HDB kitchens are often 16mm particleboard with a melamine face. | The same moisture problem, plus a management rule on debris. | Older landed joinery may be solid timber. Match the repair to the timber, not to a flat-pack hinge. |
| Hardware | Count hinges and photograph the angle before anyone buys a set. | Service lifts close early. Book the slot before the parts arrive. | Tall doors need a second person. Do not hang them alone. |
