Fire-rated sealant in Osterley, Greater London
Fire-stopping gaps in Osterley need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Linear gaps at the head of walls
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. In Osterley, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
How to prepare
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

Fire rated sealant in Osterley, done properly
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. We work on service penetrations, linear gaps and pipe & cable gaps, and common reasons people get in touch are gaps flagged on a fire risk assessment and cracked or shrunken fire-rated sealant.
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 Osterley needs to stay open, work can be planned outside normal hours.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Common problems we fix in Osterley
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
Signs it’s time to call us include:
- New service routes left unsealed after building work
- Open gaps behind door architraves
- Gaps around pipes and cables through fire-resisting walls
- Linear gaps at the head of walls
Osterley is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How the job changes by surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before applying the sealant.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for each gap size.
Leave it or put it right?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up means you can show the action was taken. In a flat in Osterley, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Quotes for fire rated sealant in Osterley
Your quote is based on your job. We take into account:
- Which sealant suits the joint
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the property is
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- The rough size of the job
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will talk you through the work and give you a clear quote.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Do not paint over fire sealant until it has cured
- Report cracked or damaged seals as soon as you notice them
- File the fire-stopping record where your assessor can find it
- Do not fill fire-stopping gaps with ordinary foam or silicone
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
Questions from Osterley
Can you help a landlord with a rental near Isleworth station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is parking an issue for fire rated sealant in Osterley?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. We use whichever the specification and tested details call for.
What fire rating will the seal have?
We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.
