Thundersley Fire Rated Sealant
Fire-stopping gaps in Thundersley need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Joints picked up in a fire-stopping survey
- Old fire sealant that has split or come away
- Gaps left after a refit or conversion
Fire rated sealant in Thundersley
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. If you are dealing with fire stopping disturbed by later work and gaps around pipes and cables through fire-resisting walls, we can put it right.
Washrooms in busy buildings wear their sealant out faster than a bathroom at home, and fire-rated joints need restoring whenever new services are run through a wall. In Thundersley, timings are planned around the building.
You get a one-year guarantee, the same in Thundersley as everywhere else we work.

Landlords, agents and businesses in Thundersley
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Can I do it myself?
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.
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.
Commercial buildings in Thundersley
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. Schools such as Thundersley Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Deciding what fire stopping a building needs
- Sign-off of the building, which sits with building control or your assessor
- Big openings where sealant alone is not the tested solution
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

What we’re called out for in Thundersley
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.
Keep an eye out for any of the following:
- Unsealed gaps around fire door frames
- Standard silicone or caulk in a fire-stopping gap
- Gaps left after a refit or conversion
- Gaps flagged on a fire risk assessment
Letting a property close to Rayleigh station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Thundersley: your questions answered
Is fire rated sealant in Thundersley guaranteed?
All our work, in Thundersley and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you help a landlord with a rental near Rayleigh station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
Different surfaces, different methods
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance.
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep the record of products and locations with your fire safety documents
- Get damaged fire seals looked at promptly
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Take pictures of fire stopping before ceilings or boxing go back
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we will tell you which one you have.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
