FD30 fire doors for Horsham buildings
Our FD30 fire doors service in Horsham is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Horsham has a broad mix of buildings, including low-rise blocks of flats, schools and care homes, and the same fire door principles apply to all of them.
In Horsham, FD30 doors are the usual choice for escape-route corridors, stairs and kitchen doors where the fire strategy asks for 30 minutes. Each FD30 leaf we supply for Horsham is sized for the opening, rather than trimmed beyond what its certification allows.
Leaf only or a full doorset?
If the existing frame is sound, correctly sized, securely fixed and compatible with the new leaf's certification, a new FD30 leaf can be hung in it. Many frames do not pass that test: old softwood linings, frames that have been cut about for previous doors, or frames with no evidence of how they were fixed. In those cases a certified doorset (leaf, frame and ironmongery tested together) is the cleaner answer and usually the quicker one on site.
We tell you which route each opening needs on the survey, door by door, and why.
Each installation includes:
- Intumescent strips and smoke seals to the certification
- Survey of the opening, frame and existing ironmongery
- Certified FD30 or FD30S leaf, or full doorset
- Fire-tested hinges, latch or lock and intumescent pads

Common questions
Is Horsham within your coverage area?
It is. We cover Horsham in West Sussex and neighbouring towns such as Crawley. There is no charge for the survey.
Can you work from an existing inspection report for my Horsham building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
Do FD30 doors need a closer?
Most do. Doors on escape routes, flat entrance doors and doors in the common parts of buildings need a self-closing device that shuts and latches the door. Some doors inside houses and locked riser doors are exceptions, depending on the fire strategy.
What is the difference between FD30 and FD30S?
FD30S has been tested for smoke control as well as fire. It adds a smoke seal, usually a brush or blade, and needs a tight threshold gap. Flat entrance doors and doors onto protected escape routes are commonly specified as FD30S.
