Fire rated sealant in Poynings, done properly
Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on service penetrations, pipe & cable gaps and plasterboard & masonry, and common reasons people get in touch are gaps left after a refit or conversion and gaps flagged on a fire risk assessment.
For holiday lets, converted business premises or a community building near Poynings, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
All our work comes with a one-year guarantee, wherever you are in West Sussex.

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

When something else is needed
In fairness, there are a few things sealant will not fix:
- Construction that does not provide fire resistance on its own
- Fire risk assessments, which need a qualified assessor
- Openings too large for sealant, which need batts, boards or another system
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

How the job changes by surface
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service against the product’s tested range.
Leave it or put it right?
Squirting in whichever sealant is nearest does not make a fire seal. 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. Where a wall is exposed, as many are in small places like Poynings, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Commercial buildings in Poynings
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
Community buildings like The Church of the Holy Trinity are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Common problems we fix in Poynings
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
If you can see any of these, it’s time to have the joints looked at:
- Unsealed gaps around fire door frames
- Sealant items on a fire risk assessment action list
- Fire stopping disturbed by later work
- Holes left by a change of layout
Rented homes near Hassocks station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Questions to ask before booking
- Whether you can choose the colour
- How much experience the applicator has
- How long to leave it before use
- What happens if they find a problem under the old sealant
