How we handle fire stopping in Middle Wallop
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on service gaps in risers, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we’re called in for most is expanding foam used as fire stopping and service penetrations left open after M&E works. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Middle Wallop it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places like Middle Wallop, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
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.

Fire stopping around Middle Wallop: points for this area
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Middle Wallop is about 69 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
Hotels like Fifehead Manor Hotel, 0.5 miles to the north-west of Middle Wallop, are refurbished in phases, and each phase can open up compartment walls. In a building such as Church of St Andrew, any service penetration through a fire-resisting wall should be sealed to the specified detail. In a school such as Wallop Primary School, fire-rated sealant goes in around service penetrations where it is specified.

What’s near Middle Wallop

Leave it or put it right?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Older rural buildings around Middle Wallop move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
What the job involves on each surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes. We confirm material and size first and tell you if sealant isn’t the right product.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.

Questions we are asked in Middle Wallop
Do you decide the fire-stopping details for buildings in Middle Wallop?
No. The designer or fire engineer sets the detail and building control accepts it. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.
Is Middle Wallop off your patch?
Not at all. Middle Wallop is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
How much does the work cost?
We don’t publish prices, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
On site: what to expect
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. For work around Middle Wallop, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Have the specification and drawings to hand
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
