What fire rated sealant looks like in Astwood
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.
If you look after a church, hall or community building such as Church of St Peter, service openings in its walls need the right fire-rated sealant, as in any building.

What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Fire risk assessments, which need a qualified assessor
- Fire doors that need new seals, closers or hardware
- Big openings where sealant alone isn’t the tested solution

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building and we leave things clean and tidy. For a village or hamlet like Astwood, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

Advice
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Signs you need fire rated sealant in Astwood
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
These are the problems we are asked about most:
- Holes left by a change of layout
- Unsealed gaps where pipes and cables go through a wall
- Fire seals that have cracked with movement
- Gaps filled with a product that isn’t fire-rated
For landlords with property near Kempston Hardwick station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Before booking anyone
- Whether all the old sealant comes out first
- Whether you can choose the colour
- How long to leave it before use
- What product goes in the joint
Why it’s worth doing now in Astwood
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Astwood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
