Fire Rated Sealant in Comp
Fire rated sealant across Comp and nearby, with old sealant always removed completely.
- Gaps around pipes and cables through fire-resisting walls
- Fire seals that have cracked with movement
- Gaps where walls meet ceilings or slabs
Why act early in Comp
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Comp, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

How we handle fire rated sealant in Comp
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. Common call-outs are for open holes round services passing through fire walls and ordinary sealant used where a fire-rated product was needed, on plasterboard & masonry, linear gaps and door frames.
For holiday lets, converted business premises or a community building near Comp, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

How the visit works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Comp, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- 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
- Clear the area around the work
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in

What else we do in Comp
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Commercial buildings in Comp
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
For buildings such as Church of St Mary, service openings in its walls need the right fire-rated sealant, as in any building. Letting a property close to Borough Green & Wrotham station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

How the job changes by surface
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before applying the sealant.
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for each gap size.
Aftercare tips
A little care helps the new joints last. We recommend:
- Include hidden areas like risers in routine checks
- Include fire stopping when you schedule refits
- Photograph sealed gaps before they’re covered up
- Never patch a fire seal with standard sealant
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
When to call us in Comp
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common particularly when it was the last job before handover.
These are the problems we’re asked about most:
- Open joints along the top of partitions
- Gaps left after a refit or conversion
- Standard silicone or caulk in a fire-stopping gap
- Fire stopping disturbed by later work
If you look after a building such as Platt Church of England Voluntary Aided Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Problems with the door itself rather than the gap around the frame
- Construction that does not provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor

Your questions about fire rated sealant in Comp
Do you cover Comp for fire rated sealant?
Yes, Comp is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Is Comp within the area you cover?
Yes, Comp is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you fill the gap behind a fire door frame?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door leaf and its hardware need a door specialist.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before work begins.
What’s the difference between intumescent and fire-rated sealant?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
How long will you be here?
That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.
Do you certify the fire stopping?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
Can you tell me which gaps need fire stopping?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.
