Fire Door Replacement vs New Installation
Most London properties that need fire door work have existing doors in place — doors that are non-compliant, damaged, or simply past their useful life. This is replacement rather than new installation, and it is the most common fire door job we carry out across London.
The key distinction when replacing a fire door is whether the existing frame can be retained or whether it needs replacing alongside the door leaf. This affects both the cost and the time on site, and it is something Doorz always checks at survey stage before any materials are ordered or priced.
Leaf-only replacement: Existing frame is reused. Faster and lower cost — but only viable where the frame is structurally sound, correctly sized and undamaged. Full door set replacement: New door leaf and certified frame. Required where the existing frame is damaged, incorrect depth, or where compliance certification of the full assembly is needed.
When Does a Fire Door Need Replacing?
Fire doors don't last forever. The following are the most common indicators we see on London inspections that a replacement is necessary rather than repair:
- Door leaf is warped, twisted or structurally damaged and cannot be corrected by adjustment
- Gap tolerances exceed 3mm on sides/top or 10mm at the floor and cannot be corrected by adjustment
- Intumescent strips have been removed, are deteriorated or are the wrong specification
- Door has been cut, planed or modified in a way that compromises its certification (this voids the rating)
- Certified glass panels have been replaced with non-rated glass
- Door closer is missing, non-functional or incorrect for the door weight
- The door is visibly old with no documentation — particularly relevant for HMO licence applications where evidence of compliance is required
One of the most common compliance failures we see in London HMOs is fire doors that have been painted over multiple times, obscuring or sealing the intumescent strips, covering gap seals and adding weight that affects self-closing. If your fire doors have multiple layers of paint on the edges or if the intumescent strips are no longer visible, a replacement assessment is strongly recommended.

FD30S vs FD60 Replacement — Which Do You Need?
The replacement specification must match or exceed the original requirement. FD30S is the standard for most London residential properties including HMOs, flats, and houses with loft conversions. FD60 is required in high-rise buildings over 11m, commercial premises and specific high-risk areas within a building. Doorz always confirms the correct specification at survey stage — we will not replace a fire door with a lower-rated product than required.
Like-for-Like Replacement Is Not Always Sufficient
If the original door was non-compliant, a like-for-like replacement may not satisfy Building Regulations or HMO licensing requirements. Doorz always replaces to current standards — not to the specification of the door being removed. This is particularly relevant for older London HMOs where original fire doors may predate current FD30S requirements.
