Fire-rated sealing for Blenheim buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Either way, we install the specified product to its tested detail. At about 48 miles from central London, Blenheim is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Campus buildings at universities such as Oxford Brookes University (to the north-west of Blenheim) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. For a building at a site such as The Boundary Business Park, 0.5 miles to the north-east of Blenheim, a check of penetration seals after each fit-out is good practice.

Fire stopping in Blenheim
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. We work on service gaps in risers, joints between fire-resisting walls and floors and cable penetrations, and the usual reasons a site gets in touch are unsealed joints where partitions meet the slab and fire stopping installed outside its tested range. A single leaking joint is often how a building in Blenheim first comes to us: we look at the rest while we’re there and tell you what we find.
Smaller places such as Blenheim still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
A 12-month guarantee applies to all our work in Oxfordshire. Should something we installed fail, speak to us on 01277 525 020 or email us and we’ll come back to it.

How the job changes by surface
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.
Blenheim: questions and answers
Will you take on work at estates like The Boundary Business Park, close to Blenheim?
Yes, sites like The Boundary Business Park are within our area, along with the rest of Blenheim. To start, just give us a call on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can work at a site such as Oxford Brookes University fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you work in Blenheim?
Yes. Blenheim is in our area and the rest of Oxfordshire, within our coverage of Greater London, South East England and Scotland. To discuss a job, call 01277 525 020 or email drawings and photos.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Cost factors for service penetrations
Quotes vary with the job. It mainly depends on:
- The size and state of each joint
- How much there is to seal
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
- When you need the work done
- Anything awkward about access or site hours
To get a fixed quote, give us a call on 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. You can also send details through our quote form.
On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If others near Blenheim need work, visits can be combined. You’ll have a fixed quote before work starts.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Tell us what induction or permit system the site runs
- Send any specification or drawings in advance
- Let building users know which areas are affected

Keeping the joints sound
To get the most from the new sealant:
- Report damaged or disturbed seals as soon as they’re spotted
- Arrange inspection before areas are covered up
- Look above ceilings when tiles are lifted for other jobs
- Don’t let anyone top up a fire seal with the wrong product
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Openings that need collars, wraps, batts or boards rather than sealant
- Issuing fire ratings or certificates for seals
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think.
Surfaces we seal
- Linear gaps at wall heads
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
