Fire stopping in Charlton
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. If you’re dealing with seals disturbed by maintenance and left open and old intumescent sealant that has split away, we can help, on small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Charlton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In places the size of Charlton, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

FAQs: Charlton
What happens to BS 476 references for fire stopping in Charlton?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is Charlton too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can staff carry on working while you are here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Leave it or put it right?
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Different surfaces, different methods
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.

What else we do in Charlton
Where services cross fire walls in Charlton
Charlton is about 57 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Charlton has five care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
Offices at parks like Elms Farm Business Park (to the north-west of Charlton) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. In a building such as Holy Trinity Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Charlton is about 7 miles west of Didcot, in Oxfordshire. We cover Charlton, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Charlton is one of 423 places we cover in Oxfordshire for service penetrations. Sites around Oxford have their own page, about 13 miles away.

Signs you need fire stopping in Charlton
Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe and the opening isn’t always resealed.
If one of these sounds familiar, it’s time for a closer look:
- Fire-stopping items raised at inspection or handover
- Seals disturbed by maintenance and left open
- Fire-rated sealant that has cracked or shrunk back
- Unsealed penetrations discovered above suspended ceilings
On a hospital site such as Wantage Community Hospital, under half a mile south-west of Charlton, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
What your quote should include
- The terms of the workmanship guarantee
- Whether primer will be used where the manufacturer specifies it
- The named product and why it was chosen
- Will RAMS and insurance details be available?
Keeping the joints sound
For the best life from the joints:
- Agree the fire-stopping specification before services go in
- Ask which product is in place before decorating
- File the specified details where the next contractor can find them
- Get seals inspected before ceilings and boxing close
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
- Removal of failed or old sealant
- Backing rod, priming and other preparation
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Sending details for a quote
To price the job accurately, we need to understand the site. Send us:
- Any specification or named product
- When you need the work done
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email drawings and photos.
