Fire rated sealant in Seal, done properly
We can work through a building room by room or floor by floor. That record is useful for your files and for whoever looks at the building next. We work on linear gaps, flats & HMOs and plasterboard & masonry, and the jobs we see most are gaps around pipes and cables through fire-resisting walls and unsealed gaps around fire door frames.
In a village or hamlet like Seal, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Big or small, you get the same one-year guarantee in Seal and across Kent.

When to call us in Seal
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.
These are the problems we’re asked about most:
- Sealant items on a fire risk assessment action list
- Seals cut through by electricians, plumbers or data installers
- Open gaps behind door architraves
- Open holes round services passing through fire walls
If you look after a church, hall or community building such as Church of St Peter and St Paul, gaps around pipes and cables are worth checking after any building work there.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Take photos of fire stopping before ceilings or boxing go back
- Include hidden areas like risers in routine checks
- Make resealing part of every contractor’s brief
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.

Fire rated sealant in Seal: local notes
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.
Managing a site like Seal Church of England Voluntary Controlled Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Why act early in Seal
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. In a small place like Seal, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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 the work is at height. Your quote takes all of that into account.
