Beckenham Fire Rated Sealant
Fire-stopping gaps in Beckenham need attention? We cut out the old, prepare the joints and apply the right sealant.
- Unsealed gaps around fire door frames
- Holes left by a change of layout
- Gaps flagged on a fire risk assessment
For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
How we handle fire rated sealant in Beckenham
Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. We work on pipe & cable gaps, linear gaps and door frames, and common reasons people get in touch are fire stopping disturbed by later work and fire seals that have cracked with movement.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Beckenham, and room-by-room programmes can be planned where needed.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Honest limits
It helps to know what we cannot do too:
- A wall that isn’t a fire-resisting element to begin with
- Openings too large for sealant, which need batts, boards or another system
- Certifying a building or signing off its fire safety

How it works
There isn’t much for you to do on the day. 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. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- 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
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Your questions about fire rated sealant in Beckenham
Can you help a landlord with a rental near Beckenham Junction station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Is parking an issue for fire rated sealant in Beckenham?
Parking in Beckenham, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Are you insured?
Yes. We’re fully insured for every job we do.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you tell me which gaps need fire stopping?
No, assessment isn’t something we do. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.
Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
How we quote for fire rated sealant
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- The type of sealant required
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before work begins.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The address or postcode of the job
- Access, such as stairs, a lift or height
- Roughly how big the job is
- Any previous sealing or DIY work
Need a quote? Please call 0345 464 0079 or send us an email and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.
Why it’s worth doing now in Beckenham
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What you get with us
- 20+ years of sealant experience
- Homes, businesses and hotels
- 180+ five-star Google reviews
- An ARBOMaster approved applicator

Commercial buildings in Beckenham
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For landlords with property near Beckenham Junction station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. As a London address, Beckenham can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

- Linear gaps at the head of walls
- Open holes round services passing through fire walls
- Open gaps behind door architraves
- Ordinary sealant used where a fire-rated product was needed
