How we handle fire rated sealant in Birchden
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on, one gap at a time. Typical jobs include old fire sealant that has split or come away and unsealed gaps where pipes and cables go through a wall, across plasterboard & masonry, door frames and linear gaps.
Work in a small place like Birchden is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
There’s a 12-month guarantee on every job.

Your questions about fire rated sealant in Birchden
Do you cover smaller places like Birchden?
Yes, Birchden is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Eridge station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Can you fill the gap behind a fire door frame?
Yes, if the gap is within the product’s tested range. Our work is the gap around the frame.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Is standard sealant good enough for a fire gap?
No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
What’s the difference between intumescent and fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.
What we are called out for in Birchden
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.
The most common problems we see are:
- Gaps where walls meet ceilings or slabs
- Open gaps behind door architraves
- Gaps around pipes and cables through fire-resisting walls
- Sealant items on a fire risk assessment action list
For buildings such as Church of St Thomas the Apostle, gaps around pipes and cables are worth checking after any building work there.
Questions to ask before you book
- The length of the guarantee
- What the cure time is
- Whether VAT is included
- Whether all the old sealant comes out first
What sealant work can’t fix
Before you book, it’s worth knowing the limits:
- Deciding what fire stopping a building needs
- Openings too large for sealant, which need batts, boards or another system
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Pipe & cable gaps
- Flats & HMOs
- Linear gaps
- Door frames
- Plasterboard & masonry
- Service penetrations
Leave it or put it right?
Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again once someone inspects it. Older cottages and farmhouses around Birchden can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The process
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. For a village or hamlet like Birchden, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit

- For business premises, tell us about site rules or sign-in

Advice
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Allow for resealing whenever new services are run
- Check whether a sealant can be painted before decorating over it
- Store the list of sealed gaps with your building paperwork
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
Different surfaces, different methods
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment, flat by flat if needed.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we will tell you.
Workplaces and buildings in Birchden
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For landlords with property near Eridge station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For site and facilities teams at buildings such as Groombridge St Thomas' Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment.
