Fire-rated sealant in Harlington, Greater London
Our applicators work in Harlington on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.

Fire rated sealant in Harlington
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. Typical jobs include open joints along the top of partitions and open holes round services passing through fire walls, on flats & HMOs, door frames and pipe & cable gaps.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Where a building in Harlington needs to stay open, work can be planned outside normal hours.
Our work is backed for twelve months.

FAQs for Harlington
Can parking be tricky for a visit in Harlington?
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.
Can you help a landlord with a rental near Heathrow Terminals 2 & 3 Rail station?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Will we have a record of what was sealed?
Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.
What do you need from me for a quote?
Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
How long will you be here?
Most jobs take from a few hours to a few days, depending on the number of gaps and the access. We will confirm how long when we quote.
What fire rating will the seal have?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.
Do you do fire sealant around door frames?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself and we will tell you if we spot problems with the door.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
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.

What fire rated sealant looks like in Harlington
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.

For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
For buildings such as Church of St Peter and St Paul, service openings in its walls need the right fire-rated sealant, as in any building. Harlington is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Why it’s worth doing now in Harlington
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job. 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 Harlington, the repair is bigger than the sealant job would have been.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why Harlington customers choose us
- ARBOMaster approved applicator
- More than 20 years in sealant work
- A 12-month guarantee on all work
- Sanitary silicone with an anti-fungal additive in wet areas
See our cost guide or what customers say.
What affects the quote in Harlington
We do not publish a price list, because no two jobs are the same. What we look at:
- Whether there’s mould to deal with
- The amount of work
- The number of rooms or windows
- Access and height
Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.
Helping us quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- Where the job is, and your postcode
- Pictures of the joints, sent by email
There’s no standard price list. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Signs you need fire rated sealant in Harlington
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.
These are the problems we are asked about most:
- Gaps flagged on a fire risk assessment
- Open gaps behind door architraves
- Open holes round services passing through fire walls
- Gaps where walls meet ceilings or slabs
Managing a site like William Byrd Primary Academy? Then fire-stopping around service openings should be restored whenever new services go in.
Questions to ask before booking
- Which sealant they’ll use, and why
- How the colour is chosen
- How hidden problems are handled
- How long to leave it before use
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Report cracked or damaged seals as soon as you notice them
- Check whether a sealant can be painted before decorating over it
- Keep photos of seals that will be hidden
- Include hidden areas like risers in routine checks
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
