What happens on the day
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a handful of gaps, and longer for a whole building. In a London area like Charlton, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints

Advice
About our fire rated sealant in Charlton
Bigger jobs can be worked through in stages, flat by flat or floor by floor. It gives you a list to keep with the building’s fire safety documents. We work on plasterboard & masonry, flats & HMOs and pipe & cable gaps, and the jobs we see most are fire seals that have cracked with movement and unsealed gaps where pipes and cables go through a wall.
In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in Charlton, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Fire rated sealant around Charlton
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. 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.
If you let a flat or house near Charlton station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as St Catherine Labouré, older buildings that have had new heating or wiring often have service gaps worth checking.

Questions from Charlton
Is parking a problem for a job in Charlton?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
I let a flat near Charlton station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you come to Charlton?
Yes. We cover Charlton, as part of our work across South East England, London and Scotland. For a quote, call 0345 464 0079 or drop us an email.
Do you certify the fire stopping?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Will we have a record of what was sealed?
Yes. You get a list of where we worked and what we used.
What happens if it’s left?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Photograph sealed gaps before they’re covered up
- File the fire-stopping record where your assessor can find it
- Allow for resealing whenever new services are run
- Do not paint over fire sealant until it has cured
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we’ll tell you which one you have.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so the item can be closed.

How the job changes by surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and the locations noted.
Signs you need fire rated sealant in Charlton
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
These are the problems we’re asked about most:
- New service routes left unsealed after building work
- Gaps flagged on a fire risk assessment
- Damaged fire sealant left by other trades
- Open gaps behind door architraves
Schools such as Thorntree Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
What to look for in a quote
- When the joint can take water or movement
- Which colour the sealant will be
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
