Fire rated sealant for homes and businesses in Lower Cox Street
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. Common call-outs are for gaps left after a refit or conversion and ordinary sealant used where a fire-rated product was needed, on plasterboard & masonry, flats & HMOs and linear gaps.
Work in a small place like Lower Cox Street is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Big or small, you get the same 12-month guarantee in Lower Cox Street and across Kent.

Is it messy?

Commercial buildings in Lower Cox Street
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, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.
Community buildings like Church of St Peter are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

When something else is needed
It helps to know what we can’t do:
- Big openings where sealant alone isn’t the tested solution
- Problems with the door itself rather than the gap around the frame
- Issuing a fire rating or certificate for a building
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.
Surfaces we seal
- Door frames
- Linear gaps
- Service penetrations
- Pipe & cable gaps
- Flats & HMOs
- Plasterboard & masonry
Looking after it afterwards
So the new joints stay in good condition:
- File the fire-stopping record where your assessor can find it
- Make resealing part of every contractor’s brief
- Include hidden areas like risers in routine checks
- Take photos of fire stopping before ceilings or boxing go back
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
What happens if it’s left?
For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. Older cottages and farmhouses around Lower Cox Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

What we’re called out for in Lower Cox Street
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.
It’s worth asking for a quote if you see:
- Fire stopping disturbed by later work
- Gaps where walls meet ceilings or slabs
- Ordinary sealant used where a fire-rated product was needed
- Gaps flagged on a fire risk assessment
If you let a flat or house near Bearsted station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
