How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. In Dulwich Village, 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.
- 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.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Fire rated sealant in Dulwich Village, done properly
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That is the part we focus on, one gap at a time. We work on linear gaps, door frames and flats & HMOs, and the jobs we see most are old fire sealant that has split or come away and gaps where walls meet ceilings or slabs.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Dulwich Village can’t close.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

When it isn’t the sealant
New sealant cannot fix everything, and we will tell you before any work starts. Sealant will not put right:
- Assessing a building’s fire safety
- Big openings where sealant alone isn’t the tested solution
- Construction that does not provide fire resistance on its own
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Fire rated sealant in Dulwich Village: local notes
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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 work to the specification you are given, installing the product to its tested details.
Dulwich Village is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Community buildings like St Barnabas' Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

When to call us in Dulwich Village
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
Most people get in touch when they notice something like this:
- Damaged fire sealant left by other trades
- Gaps around pipes and cables through fire-resisting walls
- Unsealed gaps around fire door frames
- Gaps where walls meet ceilings or slabs
For landlords with property near North Dulwich station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Your questions about fire rated sealant in Dulwich Village
Can parking be tricky for a visit in Dulwich Village?
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 work for landlords with property near North Dulwich station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Can you tell me which gaps need fire stopping?
No, assessment isn’t something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
What does intumescent mean?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
Can you fill the gap behind a fire door frame?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself, and we will mention anything we notice about the door.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on how many gaps there are, including the preparation. Your quote will say how long we expect yours to take.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Store the list of sealed gaps with your building paperwork
- Flag any open gap you spot round a pipe or cable
- Make resealing part of every contractor’s brief
- Check risers, ceiling voids and cupboards during building checks
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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.
Why deal with it now?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job that does not depend on other work. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Dulwich Village, the repair is bigger than a sealant job.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
