Even a properly certified door can cause problems if it is fitted badly or the paperwork is unclear. Choosing the right fire rated door contractor in Singapore means checking who does what, that the door is truly certified, and that you get the right papers at the end. This guide walks you through it in plain steps.
Manufacturer, Supplier, Installer: What Is the Difference?
These words are often mixed up. Here is the simple version:
- Manufacturer: makes the certified door and holds the certificate
- Supplier: sells the door, which they may or may not make
- Installer: fits the door on site
- HDB-licensed contractor: the only party allowed to file an HDB main-door permit and do the work
One company can do several of these jobs. What matters is that all of them are covered and clearly agreed.
Why Good Installation Matters
A door is only as safe as its fitting. The rating covers the whole doorset, so a crooked frame, wide gaps or a closer that does not shut the door fully can all break the rating, even on a genuine door. That is why fire door installation should be done by someone who knows fire doors.
What to Check Before You Hire
Before you sign anything, confirm these points:
- The door is certified to SS 332 or EN 1634-1 with a valid certificate
- You are getting the full doorset, not just the leaf
- The contractor has done similar jobs before
- Who files the permit
- What the fitting price includes, in writing

Questions to Ask at the Site Survey
A good contractor visits the site before quoting. Use the visit to settle the details that fix the price and the plan. Helpful questions include:
- What fire rating do I need?
- Is the old frame okay, or does it need replacing?
- Which way should the door open?
- Do I need a permit, and who files it?
- How long will making and fitting take?
Warning Signs to Watch For
Be careful if you see any of these. A price that looks too cheap can mean an uncertified copy.
- No Certificate of Conformity and no product label
- No fire rating stated
- The door is only called “solid timber”
- The contractor cannot name the standard (SS 332 or EN 1634-1)
- No written scope, no warranty, and no papers after fitting
Buy Direct From the Maker
Buying from the maker often means better advice, clearer records and more choice. A certified fire door installer may still fit the door, and for HDB main doors the permit must be filed by an HDB-licensed contractor. Boon Woh makes the doors and fits them with its own team, so it is all handled in one place.
What to Check After Fitting
Once the job is done, make sure:
- The door closes and latches fully on its own
- The frame is straight and the gaps look even
- The seals are in place and the hardware matches the quote
- The product label is there and you get the certificate and warranty

- The hardware and any digital lock
- The making time and the fitting date
- Old-door removal and any making-good work
- The warranty and payment terms
If any of these are missing, ask before you sign.
Frequently Asked Questions
Must an HDB fire door be fitted by a licensed contractor?
Yes. For an HDB main door, only an HDB-licensed contractor may file the permit and do the work.
Can I replace only the door, not the frame?
The rating covers the whole set, so the frame and hardware must suit. Check with your supplier first.
What papers should I get?
The Certificate of Conformity, the product label, hardware details, the warranty, and fitting records.
Does Boon Woh fit doors?
Yes. We supply the certified door and fit it with our own team. For HDB main doors, a licensed contractor files the permit.
Can a normal carpenter fit a fire door?
Not for an HDB main door, which needs a licensed contractor. Good fitting keeps the rating, so always use someone who knows fire doors.
What if the price looks very low?
Be careful. A very cheap door may not be certified, or may come without a frame or papers. Always check the certificate first.
Conclusion
Before you order, check the certified door, the full doorset, the installer, who files the permit, the written scope and the final papers. Those checks keep you safe and save money later.
