How we handle fire stopping in Olney
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. 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. Most enquiries involve unsealed joints where partitions meet the slab and seals disturbed by maintenance and left open, on pipe penetrations, small duct penetrations where the tested detail allows and cable penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, in Olney it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Olney, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. For a job in Olney, the main thing is a clear picture of the work. You will then get a fixed price for the work.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
Getting the site ready
- Have the specification and drawings to hand
- Tell us which areas need to stay in use
- Point out parking and an unloading spot

Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Olney: questions and answers
Do you design the fire stopping for buildings in Olney?
No, that sits with the designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.
How does the move away from BS 476 affect penetration seals in Olney?
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Can the building stay open while you work?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

How the job changes by surface
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness first.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
For managing agents and facilities managers
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Working within restricted access windows
- How much there is to seal
- Which sealant the job calls for
- The size and state of each joint
A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Photos of the joints, close up and from further back
- The type of building and who uses it
- Where the site is, with the postcode
- Approximate linear metres or a joint schedule
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Fire stopping around Olney: what changes locally
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. Our part stays the same: the specified product, installed to its tested detail. Olney lies roughly 52 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.
In a building such as Church of Saints Peter and Paul, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a hotel such as The Queen Hotel, less than half a mile north-east of Olney, penetration seals are worth checking after any refit or services upgrade.
Olney is about 9 miles north of Milton Keynes, in Milton Keynes. We send applicators to Olney for service penetrations. Olney is one of 62 places we cover in Milton Keynes. Sites around Oxford have their own page, about 36 miles away.

When to call us in Olney
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access normally bring them to light.
Clients usually get in touch after noticing something like this:
- Openings left by services added after handover
- Unsealed penetrations discovered above suspended ceilings
- Snag lists that include open service penetrations
- Unsealed joints where partitions meet the slab
Holiday works at schools like Olney Middle School often leave service openings to seal before pupils return.
