When it comes to home safety, a fire-rated main door is one of the most important features in your HDB flat. It helps contain fire and smoke, offering valuable time for your family to evacuate securely.
In Singapore, installing or replacing a fire-rated door must meet strict fire safety regulations. If you’re planning to upgrade your main door, here’s a complete step-by-step guide to ensure the process is smooth, compliant, and stress-free.

Why Fire-Rated Doors Are Essential for HDB Flats
Fire-rated doors provide protection by withstanding heat and flames for a specific time, commonly 30 or 60 minutes. This slows down the spread of fire, protecting your home and the entire block.
You must have a fire-rated door if:
- Your main door opens directly to a common corridor.
- You live in an HDB built.
- You are replacing an existing fire-rated door, even in older flats.
Step-by-Step Fire Rated Door Installation Process

Step 1: Check If You Need a Fire-Rated Door
Before you start, confirm whether your unit requires a fire-rated door:
- Check your current door — look for a certification label on the side of the door or frame.
- If unsure, consult a certified door contractor.
This step is crucial because installing a non-compliant door can lead to safety hazards and future issues.
Step 2: Choose the Right Door
Choose a door that complies with SCDF fire safety standards:
- Fire Rating: Minimum 1-hour fire resistance for most HDB flats.
- Design: Laminate, veneer, or classic wood finishes to match your home style.
- Frame Compatibility: The door and frame must be replaced together if switching to a fire-rated model.
- Digital Lock Ready: If you plan to use a digital lock, ensure its fire-rated certified.
Step 3: Professional Measurement & Quotation
The contractor will:
- Visit your home to take accurate measurements.
- Show you available designs and finishes.
- Provide a detailed quotation, including:
- Fire-rated door price
- Frame replacement
- Digital lock installation (if applicable)
- Delivery and labor charges
Step 4: Remove Old Door & Frame
On installation day, the team will:
- Carefully remove the old door and frame.
- Safe disposal provided, typically at no additional cost.
- Prepare the opening for the new door installation.
This step ensures a clean fit and proper alignment for the fire-rated door.
Step 5: Install the New Fire-Rated Door
The new door is installed with precision to meet SCDF fire safety standards:
- Frame is securely anchored to the wall.
- Door is hung and tested for smooth movement.
- Gaps are sealed to prevent smoke leakage.
- Digital lock is installed and tested.
Step 6: Final Inspection & Certification
After installation, the contractor will:
- Conduct a final safety check.
- Provide certification documents for your records.
Keep these documents safe — they may be needed for future resale or compliance checks.
