Fire rated sealant in Crouch End
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. If you are dealing with door frames with gaps between frame and wall and seals cut through by electricians, plumbers or data installers, we can help, whatever the surface.
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. Where a building in Crouch End needs to stay open, work can be planned outside normal hours.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

When to call us in Crouch End
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Most people get in touch when they notice one of these:
- Gaps where walls meet ceilings or slabs
- Unsealed gaps around fire door frames
- Joints picked up in a fire-stopping survey
- Gaps left after a refit or conversion
If you let a flat or house near Crouch Hill station, any gap left by new services in shared walls should be closed with a fire-rated product.

Fire rated sealant around Crouch End

As a London address, Crouch End can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Rokesly Infant & Nursery School, fire-stopping around service openings should be restored whenever new services go in.

Crouch End: your questions answered
Can parking be tricky for a visit in Crouch End?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work in hotels near Crouch End?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Will we have a record of what was sealed?
Yes. You get a list of where we worked and what we used to keep with your fire safety documents.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can ordinary silicone be used in a fire-stopping gap?
No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Aftercare tips
After the cure time, these simple habits help:
- Include fire stopping when you schedule refits
- Don’t paint over fire sealant until it has cured
- Report cracked or damaged seals as soon as you notice them
- Store the list of sealed gaps with your building paperwork
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.
Why it’s worth doing now in Crouch End
Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Crouch End, the repair is bigger than the sealant job would have been.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- We leave the area clean and tidy
- Fully insured
- Sanitary silicone with an anti-fungal additive in wet areas
- Old sealant always removed completely

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It generally takes a few hours for a handful of gaps, and longer for a whole building. For a job in Crouch End, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
How to prepare
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Surface by surface
Flats and HMOs
Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and record where they are.
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
