Fire stopping in Long Marston
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. If you have unsealed penetrations discovered above suspended ceilings and seals disturbed by maintenance and left open, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Long Marston it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places like Long Marston, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Leave it or put it right?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. One visit to deal with every failing joint makes more sense than several trips to a place like Long Marston. Photos of every joint help us quote for the whole job.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Penetration seals near Long Marston
Long Marston is about 35 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
For a unit at a site such as Old Airfield Industrial Estate, which lies east of Long Marston, new power or data runs between office and warehouse can breach a compartment wall. In a school such as Long Marston VA Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Building owners, agents and FMs in Long Marston
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
What we’re called out for in Long Marston
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Most enquiries start with one or more of the following:
- Damaged fire seals in risers and voids
- Seals that don’t match their tested detail
- Unsealed joints where partitions meet the slab
- Snag lists that include open service penetrations
Wherever services are added at a hospital such as Tindal Centre, 4.4 miles to the west of Long Marston, the compartment line has to be made good with the specified product.

What sets the cost
To price the job, we consider:
- How accessible the joints are
- Travel to remote or island sites
- Joint width, depth and condition
- The total length or number of joints
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What to include in your enquiry
The more we know, the firmer the quote. Helpful details to send:
- The site address and postcode
- Your programme or deadline

Advice
Common questions from Long Marston clients
Is hospital work, at somewhere like Tindal Centre, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Long Marston 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. Where we can, we group nearby jobs to make the most of each trip.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Is the BS 476 change in 2029 relevant to fire stopping?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, subject to transitional arrangements. In Scotland, the Technical Handbook sets its own guidance, including clause 2.1.14 on service penetrations.
Do you design or specify fire stopping?
No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Do the same rules apply to fire stopping in Scotland?
Our area runs from Greater London and the South East to every part of Scotland. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, using products tested for their end use.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
