Bunkers Hill: questions and answers
Is Bunkers Hill too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
What happens to BS 476 references for fire stopping in Bunkers Hill?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you fit around our working hours?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
How we handle fire stopping in Bunkers Hill
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the failures we are asked to look at most are expanding foam used as fire stopping and openings left by services added after handover. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Bunkers Hill, preparation and product choice get the time they need.
For a smaller site near Bunkers Hill, we plan to do all the penetrations in one go, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Every job we finish is backed by a 12-month workmanship guarantee, in Bunkers Hill as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
Compartment walls and floors in Bunkers Hill
Fire stopping of openings and penetrations in England falls under 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. Bunkers Hill lies roughly 58 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.
Offices at parks like Oxford Spires Business Park, 1.7 miles to the south of Bunkers Hill, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. In a building such as Church of Holy Cross, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Bunkers Hill is about 7 miles south-west of Bicester, in Oxfordshire. Anywhere in OX5, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Bunkers Hill is one of 423 places we cover in Oxfordshire for service penetrations. Oxford is covered too, around 8 miles from Bunkers Hill.

Surface by surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
Quoting for work in Bunkers Hill
Before we quote, we look at:
- The site’s rules and procedures
- How much there is to seal
- Access and working height
- Whether old sealant has to be cut out first
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- Access details, including height
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- The asbestos register, for older buildings
Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email us.
Signs you need fire stopping in Bunkers Hill
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in.
Clients normally get in touch after noticing something like this:
- Snag lists that include open service penetrations
- Fire seals cut back for extra cables and never reinstated
- Seals that don’t match their tested detail
- Head-of-wall gaps with no fire seal
For a school such as Marlborough School, penetration sealing fits best at the end of the summer works.
Comparing quotes
- Do they follow the manufacturer’s priming guidance?
- What the guarantee covers, and for how long
- Their plan for phasing and protecting the area
- Is the sealant right for the movement and the substrate?
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Bunkers Hill are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First we go through the drawings, schedule or specification for the seals.
- 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.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Point out any areas we must not close

- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
- Writing the fire-stopping specification
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think.
