Fire rated sealant in Croydon
We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We’re often asked to deal with linear gaps at the head of walls and gaps around pipes and cables through fire-resisting walls, across service penetrations, flats & HMOs 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 Croydon needs to stay open, work can be planned outside normal hours.
Your job is guaranteed for a year, as with all our work.

Why act early in Croydon
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. In a flat in Croydon, 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.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

What affects the quote in Croydon
The quote reflects the job in front of us. We take into account:
- The amount of work
- Mould in or behind the old joints
- The old material and how stubborn it is
- The product the joint needs
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Helping us quote
There’s no need for technical detail. Just tell us:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- If someone has resealed it before
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Big openings where sealant alone is not the tested solution
- A wall that is not a fire-resisting element to begin with
- Fire doors that need new seals, closers or hardware
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal

- Service penetrations

Common problems we fix in Croydon
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
People generally contact us when they notice one of these:
- Sealant items on a fire risk assessment action list
- Gaps where walls meet ceilings or slabs
- Seals cut through by electricians, plumbers or data installers
- Open holes round services passing through fire walls
Croydon is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What your quote should include
- Whether they seal over old material or remove it
- Are they insured?
- Who does the work, and how experienced they are
- How long the guarantee is
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on how many gaps there are from start to finish. In Croydon, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- 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
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
Ask for a quote
Asking for a quote is easy: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.

What fire rated sealant looks like in Croydon
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 are 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.
For landlords with property near South Croydon station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like St Andrew's are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
Croydon is about 9 miles south of London, in Greater London. Wherever you are in the CR0 postcode area, we cover fire rated sealant for homes and businesses. Across Greater London, we cover 764 places, Croydon among them. There’s also a page for London, roughly 9 miles from Croydon.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you are set on DIY, put the effort into 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.
Surface by surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Croydon questions
I let a flat near South Croydon station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Can parking be tricky for a visit in Croydon?
Parking in Croydon, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you carry out fire risk assessments?
No. We work from the specification you give us and install to the manufacturer’s details.
Do you do fire sealant around door frames?
Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
