Surface by surface
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each and we flag any that need another system.
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run.
Fire rated sealant for homes and businesses in Northwick Park
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment for buildings in Northwick Park. Send us the list or the survey and we will quote for the fire-rated sealant work on it. Common call-outs are for unsealed gaps around fire door frames and old fire sealant that has split or come away, on linear gaps, pipe & cable gaps and plasterboard & masonry.
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 Northwick Park cannot close.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Looking after it afterwards
To keep the joints looking good and working properly:
- Include fire stopping when you schedule refits
- Make resealing part of every contractor’s brief
- Keep the record of products and locations with your fire safety documents
- Check risers, ceiling voids and cupboards during building checks
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
What we can’t put right
A few problems are outside what sealant work can do:
- Certifying a building or signing off its fire safety
- Walls or floors that weren’t built to resist fire
- Large holes that need a different fire-stopping system
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Common problems we fix in Northwick Park
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
The problems people usually mention when they call include:
- Open joints along the top of partitions
- Holes left by a change of layout
- Gaps around pipes and cables through fire-resisting walls
- Cracked or shrunken fire-rated sealant
Managing a site like Harrow High School? Then fire-stopping around service openings should be restored whenever new services go in.
What your quote should include
- The length of the guarantee
- Who does the work, and how experienced they are
- How long to leave it before use
- What happens if they find a problem under the old sealant
Commercial buildings in Northwick Park
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. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
Community buildings like Saint Cuthberts Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Letting a property close to Kenton station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Why deal with it now?
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Northwick Park, the repair is bigger than the sealant job would have been.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

How the visit works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal.

- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
