Fire rated sealant in Harold Park
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. If you are dealing with gaps flagged on a fire risk assessment and unsealed gaps around fire door frames, we can help. As specialist sealant applicators, we cover Harold Park for fire rated sealant and other sealant work.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Harold Park cannot close.
Whatever the size of the job, it’s backed by our one-year guarantee in Harold Park and across Greater London.

How the job changes by surface
Flats and HMOs
In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance so residents know what to expect.
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
What happens if it’s left?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Harold Park.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear quote before any work starts.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Plan fire stopping into any work that goes through walls or floors
- Keep photos of seals that will be hidden
- Store the list of sealed gaps with your building paperwork
- Look in service cupboards and ceiling voids from time to time
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we’ll tell you which one you have.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.
Workplaces and buildings in Harold Park
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like St Paul 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, Harold Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Schools such as Harold Court Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

When it is not the sealant
In fairness, some problems need a different trade:
- Openings too large for sealant, which need batts, boards or another system

- Walls or floors that weren’t built to resist fire
