- A wall that isn’t a fire-resisting element to begin with
- Fire doors that need new seals, closers or hardware
- Assessing a building’s fire safety

Fire rated sealant in Hill End, done properly
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through. We are often asked to deal with unsealed gaps where pipes and cables go through a wall and old fire sealant that has split or come away, on service penetrations, door frames and plasterboard & masonry. As specialist sealant applicators, we cover Hill End for fire rated sealant and other sealant work.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Hill End, and room-by-room programmes can be planned where needed.
The work is covered for a year after we finish. If anything isn’t right with it, call 07833 053749 or send us an email.

Looking after it afterwards
Looking after new joints is easy:
- Check whether a sealant can be painted before decorating over it
- Look in service cupboards and ceiling voids from time to time
- Take pictures of fire stopping before ceilings or boxing go back
- Store the list of sealed gaps with your building paperwork
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
Fire rated sealant in Hill End: local notes
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.
Managing a site like Harefield Infant School? Then fire-stopping around service openings should be restored whenever new services go in. Community buildings like Harefield Baptist Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of gaps, and longer for a whole building from start to finish. 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.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
How to prepare
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Advice
DIY versus a professional finish
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Why act early in Hill End
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 07833 053749 or email us for an honest opinion and a quote.

Yes, we work for landlords and agents. Just ring 07833 053749 or email us and tell us about the property, and we will send you a clear quote.
Is parking an issue for fire rated sealant in Hill End?
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.
How long does fire rated sealant take?
That depends on how much there is to do, but as a guide it takes a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.
Can you tell me how many minutes the seal will last?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
Do you take on fire stopping in schools and offices?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Are you insured?
Yes. We are fully insured.
