Fire rated sealant for homes and businesses in Nuneham Courtenay
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. If you’re dealing with ordinary sealant used where a fire-rated product was needed and new service routes left unsealed after building work, we can help.
If you have holiday lets, a converted barn used for business or a community building near Nuneham Courtenay, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
You get a 12-month guarantee, the same in Nuneham Courtenay as everywhere else we work.

What fire rated sealant looks like in Nuneham Courtenay
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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Schools such as Marsh Baldon Church of England Controlled School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near Radley station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St Peter, gaps around pipes and cables are worth checking after any building work there.

Different surfaces, different methods
Service penetrations
New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth with backing where the detail needs it.
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.
Why it’s worth doing now in Nuneham Courtenay
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Older cottages and farmhouses around Nuneham Courtenay can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we’ll talk you through it.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Tell trades working in the building that fire seals must be put back
- Flag any open gap you spot round a pipe or cable
- Check risers, ceiling voids and cupboards during building checks
- Allow for resealing whenever new services are run
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.
What we do, step by step
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of gaps, and longer for a whole building in most cases. Somewhere like Nuneham Courtenay needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.

Nuneham Courtenay questions
Can you help a landlord with a rental near Radley station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Nuneham Courtenay?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can ordinary silicone be used in a fire-stopping gap?
No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How long does fire rated sealant take?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
What fire rating will the seal have?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
