Fire rated sealant around Kemprow
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For landlords with property near Radlett station, any gap left by new services in shared walls should be closed with a fire-rated product. Schools such as Fair Field Junior School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

About our fire rated sealant in Kemprow
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We work on linear gaps, pipe & cable gaps and plasterboard & masonry, and people most often call us about damaged fire sealant left by other trades and gaps left after a refit or conversion.
If you have holiday lets, a converted barn used for business or a community building near Kemprow, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

What happens if it’s left?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. 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 Kemprow, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What the job involves on each surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
Flats and HMOs
Conversions usually leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.
Honest limits
A few problems are outside what sealant work can do:
- Doors that are not fire doors in the first place
- Construction that does not provide fire resistance on its own
- Big openings where sealant alone isn’t the tested solution
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

Do you need fire rated sealant in Kemprow?
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
It’s worth asking for a quote if you see:
- Gaps filled with a product that isn’t fire-rated
- Fire seals that have cracked with movement
- Linear gaps at the head of walls
- Gaps around pipes and cables through fire-resisting walls
If you look after a church, hall or community building such as St John, gaps around pipes and cables are worth checking after any building work there.
What to look for in a quote
- How much experience the applicator has
- What product goes in the joint
- How the surfaces are prepared before sealing
- How long the guarantee is
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Kemprow questions
Is Kemprow in your area for fire rated sealant?
Yes, Kemprow is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Do you cover smaller places like Kemprow?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.

How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Kemprow, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
