Fire-rated sealant in Chiswick, Greater London
Our applicators work in Chiswick on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

Fire rated sealant in Chiswick
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. Common call-outs are for old fire sealant that has split or come away and gaps left after a refit or conversion, across door frames, service penetrations and plasterboard & masonry.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Where a building in Chiswick needs to stay open, work can be planned outside normal hours.
There’s a 12-month guarantee on every job, large or small.

What we can’t put right
In fairness, some problems need a different trade:
- Deciding what fire stopping a building needs
- Fire doors that need new seals, closers or hardware
- A wall that is not a fire-resisting element to begin with
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Common problems we fix in Chiswick
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.
Signs it’s time to call us include:
- Gaps filled with a product that isn’t fire-rated
- Door frames with gaps between frame and wall
- Linear gaps at the head of walls
- Joints picked up in a fire-stopping survey
Community buildings like St. Nicholas Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
What your quote should include
- Who does the work, and how experienced they are

- Whether all the old sealant comes out first
- Whether the sealant suits the joint
Commercial buildings in Chiswick
There are hotels and other places to stay in and around Chiswick. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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 work to the specification you’re given, installing the product to its tested details.
If you look after a building such as The William Hogarth Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. As a London address, Chiswick can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Surface by surface
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth with backing where the detail needs it.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail, and we’ll tell you.
Questions from Chiswick
Is parking a problem for a job in Chiswick?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work in hotels near Chiswick?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Do you certify the fire stopping?
Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.
How do I get a quote for fire rated sealant in Chiswick?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you seal gaps around fire door frames?
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.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
What affects the cost of fire rated sealant
Call for a quick quote. What matters most is:
- The type of sealant required
- How many areas need sealing
- Any working-time requirements on site
- How easy the joints are to reach
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Any access issues, like height or stairs
- The type of property
- The rough size of the job
For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Chiswick, the repair is bigger than the sealant job would have been.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
