How we handle fire rated sealant in Telegraph Hill
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We’re often asked to deal with open holes round services passing through fire walls and open gaps behind door architraves, across plasterboard & masonry, service penetrations and linear gaps.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Where a building in Telegraph Hill needs to stay open, work can be planned outside normal hours.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Why it’s worth doing now in Telegraph Hill
For some gaps, sealant is not the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we’ll tell you. In a flat in Telegraph Hill, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Common questions in Telegraph Hill
Is Telegraph Hill in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Telegraph Hill is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.
Is parking an issue for fire rated sealant in Telegraph Hill?
Parking in Telegraph Hill, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is standard sealant good enough for a fire gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you fill the gap behind a fire door frame?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door leaf and its hardware need a door specialist.
Can you work in occupied 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.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
What we’re called out for in Telegraph Hill
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried.
If you can see any of these, it’s time to have the joints looked at:
- Holes left by a change of layout
- Gaps where walls meet ceilings or slabs
- Fire stopping disturbed by later work
- Ordinary sealant used where a fire-rated product was needed
For landlords with property near Brockley station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

The work is kept neat and contained to the area we’re working on, so you can carry on as normal.

- Old or unsuitable sealant is cut out and the gap cleaned.

Quotes for fire rated sealant in Telegraph Hill
You’ll get a clear quote before we start. It takes into account:
- The old material and how stubborn it is
- How many areas need sealing
- Whether there’s mould to deal with
- Any working-time requirements on site
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.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- Any previous sealing or DIY work

Surface by surface
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.
Door frames
Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist, and we will say if we spot a problem with them.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Problems with the door itself rather than the gap around the frame
- Construction that doesn’t provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal

Fire rated sealant in Telegraph Hill: 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, 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.
As a London address, Telegraph Hill 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 Haberdashers' Hatcham College, fire-stopping around service openings should be restored whenever new services go in.
