In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in West Hendon, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Flag any open gap you spot round a pipe or cable
- Don’t paint over fire sealant until it has cured
- Ask every contractor to reseal any fire stopping they disturb
- Keep general-purpose foam and caulk away from fire-stopping gaps
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When to call us in West Hendon
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
Most people get in touch when they notice one of these:
- Ordinary sealant used where a fire-rated product was needed
- Linear gaps at the head of walls
- Fire stopping disturbed by later work
- Old fire sealant that has split or come away
West Hendon is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before booking
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
- How long the guarantee is
- Whether the sealant suits the joint
Surface by surface
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Issuing a fire rating or certificate for a building
- Walls or floors that weren’t built to resist fire
- Doors that aren’t fire doors in the first place
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Your questions about fire rated sealant in West Hendon
Can parking be tricky for a visit in West Hendon?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you work in hotels near West Hendon?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.
How long does fire rated sealant take?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer, and we’ll say how long yours will take.
How much does fire rated sealant cost in West Hendon?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
How it works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. For a job in West Hendon, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
