Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How a job runs
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 we finish with a walk round so the work can be signed off. If others near Bar End need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Flag any permit to work we will need
- Send any specification or drawings in advance
Getting a fixed quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send photos by email.

Fire stopping for commercial buildings in Bar End
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. Site teams most often ask us about damaged fire seals in risers and voids and head-of-wall gaps with no fire seal, across small duct penetrations where the tested detail allows, pipe penetrations and service gaps in risers. For commercial sealant work in Bar End, you deal with one contact from quote to sign-off, whether it’s one building or several.
Rural conversions around Bar End can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Cost factors for service penetrations
These are the things that shape the price:
- Access and working height
- Travel to remote or island sites
- Phasing around occupants
- Backing rod, priming and other preparation
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
- A wide shot and a close-up of the area
- What the building is and how it’s used
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Surface 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 before sealing.
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
Compartment walls and floors in Bar End
Central London is about 61 miles from Bar End. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. The 2 miles around Bar End include two care or nursing homes. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. We install fire-rated sealant to the tested detail where it is specified.
Residences at universities like University of Winchester, 1.2 miles north-west of Bar End, have compartment walls that must be resealed whenever services change. Theatres, wards and plant rooms at sites like Leigh House Hospital (1.1 miles north-east of Bar End) all have compartment walls crossed by services. Colleges such as Peter Symonds College, 1.4 miles north-west of Bar End, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Signing off or certifying a building’s fire stopping
- Writing the fire-stopping specification
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Pipe penetrations
- Cable penetrations
Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Check with the data sheet before painting over fire sealant
- Check risers and ceiling voids after each round of works
- Arrange inspection before areas are covered up
- File the specified details where the next contractor can find them
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
What happens if it’s left?
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small. Older rural buildings around Bar End move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Your questions answered
Can you seal around new services in a hotel near Bar End?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Bar End?
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’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
