Fire rated sealant in East Barnet, 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’s the part we focus on, gap by gap. If you’re dealing with old fire sealant that has split or come away and sealant items on a fire risk assessment action list, we can help.
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 East Barnet needs to stay open, work can be planned outside normal hours.

Your questions about fire rated sealant in East Barnet
Is parking a problem for a job in East Barnet?
Parking in East Barnet, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can you help a landlord with a rental near Oakleigh Park station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
How long does the job take?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer.
Do you guarantee your work?
Yes. Every job comes with a one-year guarantee.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do you seal gaps around fire door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product, to the product’s details. The door, its seals and closer are for a door specialist.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Fire rated sealant around East Barnet
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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
Community buildings like St Mary the Virgin are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Letting a property close to Oakleigh Park station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Why act early in East Barnet
Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. 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 East Barnet, the repair is bigger than the sealant job would have been.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Signs you need fire rated sealant in East Barnet
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 doesn’t always get resealed.
If you can see any of these, it’s time to have the joints looked at:
- Unsealed gaps around fire door frames
- Standard silicone or caulk in a fire-stopping gap
- Gaps where walls meet ceilings or slabs
- Open holes round services passing through fire walls
If you look after a building such as Church Hill School, service openings in fire-resisting walls need checking after any refurbishment.
Questions to ask before booking
- How much experience the applicator has
- How long the guarantee is
- What product goes in the joint
- When the joint can take water or movement
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Allow for resealing whenever new services are run
- Keep photos of seals that will be hidden
- Never patch a fire seal with standard sealant
- Check whether a sealant can be painted before decorating over it
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we will tell you which one you have.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes from a few hours to a few days, depending on the number of gaps and the access. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
