Fire rated sealant for homes and businesses in Throwley
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, gap by gap. Common call-outs are for cracked or shrunken fire-rated sealant and gaps filled with a product that isn’t fire-rated, across service penetrations, pipe & cable gaps and door frames.
Somewhere as small as Throwley, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
All our work is covered by a 12-month guarantee, wherever you are in Kent.

Workplaces and buildings in Throwley

Community buildings like Church of St Michael and All Angels are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep the record of products and locations with your fire safety documents
- Take photos of fire stopping before ceilings or boxing go back
- Get damaged fire seals looked at promptly
- Include hidden areas like risers in routine checks
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot and we will tell you which one you have.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
Common problems we fix in Throwley
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Any of these means the joints need attention:
- Unsealed gaps around fire door frames
- Gaps filled with a product that isn’t fire-rated
- Joints picked up in a fire-stopping survey
- Open joints along the top of partitions
If you let a flat or house near Faversham station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
What your quote should include
- What happens if the job turns out different
- What insurance they hold
- How the colour is chosen
- When the joint can take water or movement
Why act early in Throwley
A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In a small place like Throwley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

- Assessing a building’s fire safety
