What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Writing the fire-stopping specification
- Reviewing a building’s overall fire safety
- Construction that lacks the fire resistance the seal relies on
If you’re not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
Fire stopping in Cottonworth
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. We work to the product’s tested detail for every seal, not a rule of thumb. If you’re dealing with unsealed joints where partitions meet the slab and hidden openings found during inspections, we can put it right. A specialist sealant contractor works differently from a general builder: in Cottonworth, that means joint design, primers and backing rod as standard.
For a smaller site near Cottonworth, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Surface by surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables and we work within those limits.
From enquiry to sign-off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Cottonworth are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Move anything stored against the joints
- Point out any areas we must not close
- Warn occupants and staff about the work

Looking after the joints
Regular inspection catches problems early. Specifically:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Flag new cables with no seal around them
- Don’t let anyone top up a fire seal with the wrong product
- Include service cupboards in routine inspections
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
For managing agents and facilities managers
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
Signs you need fire stopping in Cottonworth
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it.
Things that typically lead to an enquiry:
- Unsealed penetrations discovered above suspended ceilings
- Openings left by services added after handover
- Non-fire-rated filler around services
- Open linear gaps along the top of fire-resisting walls
On estates like Harewood Forest Industrial Estate, 2.9 miles to the north-east of Cottonworth, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Fire stopping in Cottonworth: the local picture
At about 63 miles from central London, Cottonworth is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Older community buildings such as Church of St Mary the Less that have been rewired or given new heating can have service gaps through walls worth checking against the specification. On a hospital site such as Andover War Memorial Hospital, 4.4 miles to the north of Cottonworth, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Cottonworth is about 4 miles south of Andover, in Hampshire. Across the SP11 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 723 places in Hampshire. Southampton is covered too, some 17 miles away.
Anyone looking for fire stopping in SP11 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. We also cover Fullerton (1 mile south-west), Chilbolton (1 mile east), Wherwell (1 mile north-east), Wherwell Wood (1 mile north) and Leckford (1 mile south) for service penetrations. Further afield, our area takes in Winchester (9 miles south-east), Eastleigh (14 miles south), Andover (4 miles north), Chandler's Ford (12 miles south), Romsey (11 miles south) and Hyde (9 miles south-east).

Your questions answered
Is a smaller place like Cottonworth outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What does the BS 476 change mean for fire-rated sealant in Cottonworth?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
