Fire doors are a critical component of any building’s safety system, helping to slow the spread of fire and protect lives. If you’re planning a fire door installation, one of the most common questions is: how long does it take to fit a fire door?
The answer depends on several factors, from the type of door to the complexity of the installation.
Factors Affecting Installation Time
- Type of Fire Door
Standard timber fire doors typically take less time to fit than steel or bespoke doors. Pre-hung doors (doors already fitted into a frame) are faster to install than doors fitted into an existing frame. - Preparation and Measurements
Accurate measurements are crucial. If adjustments to the frame or surrounding structure are needed, this can add time. - Fittings and Hardware
Installing the correct hinges, fire-rated locks, door closers, and seals takes time. Each component must meet fire safety standards, and incorrect installation can compromise the door’s effectiveness. - Number of Doors
Installing multiple doors in a single property or building will naturally take longer, though installers often become more efficient as they progress.
So, How Long Does it Take to Fit a Fire Door?
Here’s a breakdown of how long it usually takes professionals to fit different types of fire doors:
- Single, pre-hung timber fire door: Around 1 to 2 hours
- Standard timber fire door (with separate frame): Around 2 to 3 hours
- Steel or bespoke fire door: Around 3 to 4 hours
- Multiple doors in a residential property (3–6 doors): Typically 1 to 2 days
- Larger commercial projects: Can take several days to weeks depending on scale
Note: These times assume professional installation. DIY fitting is not recommended, as even minor mistakes can reduce fire protection performance.
Importance of Professional Installation
Fire doors must comply with British Standards (BS 476 or EN 1634-1). Incorrect installation—misaligned frames, gaps, or non-compliant hardware—can invalidate insurance and put lives at risk. Professional installers ensure the door functions correctly, including self-closing mechanisms and smoke seals.
Conclusion
While a single fire door can often be fitted in a couple of hours, the total time depends on the type of door, preparation, and number of installations.
Always use trained professionals to ensure compliance and safety.
Remember: a fire door isn’t just a door—it’s a lifesaving barrier.
