Fire stopping in Up Somborne: the local picture
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 64 miles from Up Somborne. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.
For a site team at a college like Sparsholt College Rifle Range, 1.3 miles east of Up Somborne, fire-rated sealing is best scheduled after the summer works. Large healthcare estates like Royal Hampshire County Hospital (4.9 miles south-east of Up Somborne) change their services often, so penetration seals are worth checking after M&E work.
Up Somborne is about 5 miles north-west of Winchester, in Hampshire. Commercial clients in Up Somborne can call on us for service penetrations, as part of our coverage of Hampshire.

How we handle fire stopping in Up Somborne
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. 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 rather than guesswork. The enquiries we see most involve unsealed penetrations discovered above suspended ceilings and snag lists that include open service penetrations, on linear gaps at wall heads, service gaps in risers and pipe penetrations. For commercial sealant work in Up Somborne, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Rural conversions around Up Somborne can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- File the specified details where the next contractor can find them
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Ask the designer to confirm details early on refits
- Treat an open penetration as a priority repair
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.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
Surface by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products.
Questions about Up Somborne
Can you work at a site such as Balldown Business Centre, by Up Somborne?
Yes. We cover Up Somborne and the area around it, including industrial estates, business parks and retail parks such as Balldown Business Centre. Send details of the unit and the work through our quote form for a quick quote.
How does the move away from BS 476 affect penetration seals in Up Somborne?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Can you work while the building is occupied?
In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

What we’re called out for in Up Somborne
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.
Any of the following is a good reason to get the joints checked over:
- Non-fire-rated filler around services
- Fire sealant pulled out of the opening
- Openings found when ceilings come down for a refit
- Unsealed joints where partitions meet the slab
On a site such as Balldown Business Centre, which lies east of Up Somborne, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

When it isn’t the sealant
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Deciding what a wall or floor needs, which belongs to the designer
- Walls or floors that aren’t fire-resisting to begin with
- Approving the work on behalf of building control
If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Surfaces we seal
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
Leave it or put it right?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Halls, stores and units around places like Up Somborne may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
