How it works
The work is kept neat and contained to the area we are working on. The job generally takes a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Eltham. A visitor permit or a nearby bay makes the visit run more smoothly.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

Fire rated sealant for homes and businesses in Eltham
We often work from an action list drawn up by a fire risk assessor on buildings across Eltham. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. Typical jobs include unsealed gaps where pipes and cables go through a wall and open gaps behind door architraves, across pipe & cable gaps, plasterboard & masonry and service penetrations.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Eltham, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Our work is backed for twelve months.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Check risers, ceiling voids and cupboards during building checks
- Ask which product was used before you paint
- Include fire stopping when you schedule refits
- File the fire-stopping record where your assessor can find it
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
Common questions in Eltham
Is parking a problem for a job in Eltham?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you cover Eltham for fire rated sealant?
Yes, Eltham is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Is intumescent sealant the same as fire-rated sealant?
An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Will you assess my building’s fire safety?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
How long will you be here?
A typical job takes from a few hours to a few days, depending on the number of gaps and the access, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do you work in flats, HMOs and commercial buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.
What affects the cost of fire rated sealant
The quote reflects the job in front of us. We look at:
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Any working-time requirements on site
- How easy the joints are to reach
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- A few pictures by email, if you can
- What’s wrong with the joints now
If you are in Eltham and need fire rated sealant, call 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Workplaces and buildings in Eltham
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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Community buildings like Church of Holy Trinity are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. As a London address, Eltham can be tricky for parking: let us know about parking bays, permits or a driveway.

What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Certifying a building or signing off its fire safety
- Fire risk assessments, which need a qualified assessor
- Fire doors that need new seals, closers or hardware
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.
Surfaces we seal
- Door frames
- Service penetrations
- Plasterboard & masonry
- Pipe & cable gaps
- Flats & HMOs
- Linear gaps
When to call us in Eltham
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 does not always get resealed.
Keep an eye out for any of the following:
- Joints picked up in a fire-stopping survey
- Fire seals that have cracked with movement
- Linear gaps at the head of walls
- Ordinary sealant used where a fire-rated product was needed
If you let a flat or house near Mottingham station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Different surfaces, different methods
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it.
