Fire stopping for commercial buildings in Cranbourne
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on pipe penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are unsealed joints where partitions meet the slab and unsealed penetrations discovered above suspended ceilings. Facilities teams, main contractors and managing agents in Cranbourne tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a smaller site near Cranbourne, we plan to do all the penetrations in one go, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to bring in a specialist
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.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Looking after the joints
A few simple habits keep the new joints working:
- Record which product was used where
- Settle who seals which penetrations at the start of a project
- Don’t let anyone top up a fire seal with the wrong product
- Look above ceilings when tiles are lifted for other jobs
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Why act early in Cranbourne
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. Halls, stores and units around places like Cranbourne may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Common questions from Cranbourne clients
Can you work on a hospital site such as King Edward VII Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Cranbourne too far out for you?
Not at all. Cranbourne is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
What do BS EN 1366-3 and BS EN 13501-2 mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested and the installation has to match the test.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

When to call us in Cranbourne
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
Look out for the following:
- Openings left by services added after handover
- Improvised or mixed-product fire seals
- Fire-stopping items raised at inspection or handover
- Builders’ foam or ordinary silicone in compartment walls
In a school such as Cranbourne Primary School, fire-rated sealant goes in around service penetrations where it is specified.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Who will actually carry out the work
- Proof of insurance

Fire stopping in Cranbourne: the local picture
Cranbourne lies roughly 25 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. There are several hotels within about 2 miles of Cranbourne. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
Older community buildings such as Church of St Peter that have been rewired or given new heating can have service gaps through walls worth checking against the specification. On a hospital site such as King Edward VII Hospital (2.9 miles north-east of Cranbourne), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Cranbourne is about 3 miles south-west of Windsor, in Bracknell Forest. Commercial clients in Cranbourne can call on us for service penetrations, as part of our coverage of Bracknell Forest.

Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For work around Cranbourne, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- 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.
