The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. In Upton Park, 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.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- 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.
- Locations and products are noted so you have them on file.
Before we arrive
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

About our fire rated sealant in Upton Park
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. Common call-outs are for linear gaps at the head of walls and standard silicone or caulk in a fire-stopping gap, across flats & HMOs, plasterboard & masonry and pipe & cable gaps.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Where a building in Upton Park needs to stay open, work can be planned outside normal hours.
All our work comes with our 12-month guarantee.

Why act early in Upton Park
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. 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 Upton Park, the repair is bigger than the sealant job would have been.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Upton Park questions
Can parking be tricky for a visit in Upton Park?
Parking in Upton Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you cover Upton Park for fire rated sealant?
Yes, Upton Park is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What fire rating will the seal have?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Do you carry out fire risk assessments?
No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.
Can you give us a record of the work?
Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.
Work for landlords, hotels and businesses
For anyone letting property in or around Upton Park, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and photos by email help.
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.
Common problems we fix in Upton Park
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
Signs it’s time to call us include:
- Open joints along the top of partitions
- Open holes round services passing through fire walls
- Fire seals that have cracked with movement
- Ordinary sealant used where a fire-rated product was needed
If you look after a church, hall or community building such as St Martin's Church, service openings in its walls need the right fire-rated sealant, as in any building.

What we can’t put right
We will always be straight with you, so here’s what new sealant will not do:
- Issuing a fire rating or certificate for a building
- A wall that isn’t a fire-resisting element to begin with
- Fire doors that need new seals, closers or hardware
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Door frames
- Linear gaps
- Plasterboard & masonry
- Flats & HMOs
- Pipe & cable gaps
- Service penetrations
Other services in Upton Park
Different surfaces, different methods
Plasterboard walls
We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.
Workplaces and buildings in Upton Park
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, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.
As a London address, Upton Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as St Edward's Catholic Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
