Fire rated sealant in Withermarsh Green, done properly
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on linear gaps, door frames and pipe & cable gaps, and the jobs we see most are joints picked up in a fire-stopping survey and gaps filled with a product that isn’t fire-rated.
Somewhere as small as Withermarsh Green, 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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Why act early in Withermarsh Green
Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we’ll tell you. Where a wall is exposed, as many are in small places like Withermarsh Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Take pictures of fire stopping before ceilings or boxing go back
- Report cracked or damaged seals as soon as you notice them
- Never patch a fire seal with standard sealant
- Ask which product was used before you paint
Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

Advice
Signs you need fire rated sealant in Withermarsh Green
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.
Keep an eye out for these signs:
- Linear gaps at the head of walls
- Door frames with gaps between frame and wall
- New service routes left unsealed after building work
- Gaps filled with a product that isn’t fire-rated
For jobs in and around Withermarsh Green, choosing the right material for each joint is as important as a tidy finish.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
