Fire rated sealant in Chelsfield
We can work through a building room by room or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents. If you have unsealed gaps where pipes and cables go through a wall and open joints along the top of partitions, we can help, whatever the surface.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Chelsfield, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Whatever the size of the job, you get the same one-year guarantee in Chelsfield and across Greater London.

Can I do it myself?
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.
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.

Do you remove the old sealant?

Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.
Will you assess my building’s fire safety?
No. That’s for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can you fill the gap behind a fire door frame?
Yes, if the gap is within the product’s tested range. Our work is the gap around the frame.
What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes a few hours for a handful of gaps, and longer for a whole building. In Chelsfield, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Before we arrive
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

What else we do in Chelsfield
What we cannot put right
To be straight with you, there are a few things sealant will not fix:
- Fire risk assessments, which need a qualified assessor
- Construction that doesn’t provide fire resistance on its own
- Fire doors that need new seals, closers or hardware
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Linear gaps
- Pipe & cable gaps
- Service penetrations
- Door frames
- Flats & HMOs
- Plasterboard & masonry
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep the record of products and locations with your fire safety documents
- Include hidden areas like risers in routine checks
- Never patch a fire seal with standard sealant
- Don’t paint over fire sealant until it has cured
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
How the job changes by surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Why deal with it now?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.

- Trusted Arbo and Everbuild sealants

Fire rated sealant around Chelsfield
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. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
If you look after a building such as Chelsfield Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Church of St Martin of Tours are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. As a London address, Chelsfield can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
