How to pick a contractor for SERS shelter in Singapore
A flat under SERS will be handed back to HDB, so any work on the household shelter (bomb shelter) should be practical and reversible. This HDB Renovation Guide Singapore chapter walks through choosing a contractor for shelter works and the material choices with durability and price notes. The core answer is simple. Pick an HDB-registered contractor, keep the shelter structure untouched, and spend only on materials you can leave behind without regret.
Why contractor choice matters under SERS
SERS means the flat is on a fixed path to demolition and rehousing. You still want the shelter to store things neatly and stay dry, but you should not invest in permanent upgrades. A registered contractor protects you because only HDB-registered contractors may carry out regulated works, and firms under CaseTrust with Renovation Continuity Insurance (RCI) cover you if the contractor goes insolvent.
How to choose the right contractor
- Confirm HDB registration on the RCRS list before asking for a quote.
- Ask for CaseTrust accreditation and RCI cover; both protect your deposit.
- Request a written quote that lists materials, not just a lump sum.
- Check past shelter jobs and whether the owner kept the structure intact.
- Avoid anyone who suggests hacking the shelter wall or door; walk away.
Material choices with durability and price
Inside the shelter, moisture-resistant plywood costs about S$60 to S$120 per sheet and handles humidity better than plain board. Melamine shelving runs S$25 to S$50 per linear foot and is easy to wipe. For the floor, a vinyl overlay at S$3 to S$6 per square foot resists damp and leaves without loss. Epoxy coating on the concrete floor costs S$6 to S$10 per square foot and lasts longer but is harder to justify for a flat you will exit.
For lighting, a simple LED strip on a plug (S$20 to S$45) beats a wired point you must declare. Keep wiring out of the structure.
Mistakes to avoid with shelter contractors
- Do not pay the full sum upfront. Stage payments against completed work.
- Do not let anyone paint over the shelter's required markings.
- Do not skip the written scope; verbal promises fade fast.
- Do not choose the cheapest bid if it lacks insurance cover.
Frequently asked questions
Can a SERS shelter be fully converted to a room? No. The walls, door, and frame must stay, so a true conversion is not allowed. You can fit it out for storage only.
Will HDB check the shelter at handover? Yes, the shelter must remain intact and identifiable, so any unapproved change can cause trouble during the return process.
Is a renovation loan available? HDB's loan up to S$30,000 is for resale flat buyers, not SERS moves. Plan shelter works within your own budget.
Choosing a contractor for a SERS shelter is less about ambition and more about safety and paperwork. Use a registered, insured firm, keep the structure whole, and pick cheap, damp-resistant materials. The shelter stays useful now and the handover stays clean later.
