DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
About our fire rated sealant in St Helier
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you have standard silicone or caulk in a fire-stopping gap and unsealed gaps where pipes and cables go through a wall, we can put it right.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in St Helier cannot close.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Check whether a sealant can be painted before decorating over it
- Ask every contractor to reseal any fire stopping they disturb
- Report cracked or damaged seals as soon as you notice them
- File the fire-stopping record where your assessor can find it
Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.

How the job changes by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.
What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. The work normally takes a few hours for a handful of gaps, and longer for a whole building. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in St Helier. A visitor permit or a nearby bay makes the visit run more smoothly.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

Workplaces and buildings in St Helier
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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
Rented homes near Sutton Common station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For site and facilities teams at buildings such as Tweeddale Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like St Peter's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Construction that doesn’t provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor
- Big openings where sealant alone isn’t the tested solution

Why deal with it now?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Your questions about fire rated sealant in St Helier
Is parking a problem for a job in St Helier?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you cover St Helier for fire rated sealant?
Yes, St Helier is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing.
Can you quote for more than one area?

Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you seal gaps around fire door frames?
Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
