Fire stopping across Castle Green
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Why deal with it now?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. Older rural buildings around Castle Green 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.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Fire stopping for commercial buildings in Castle Green
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations, and the failures we’re asked to look at most are openings found when ceilings come down for a refit and fire-stopping items raised at inspection or handover. Looking for mastic applicators who cover Castle Green? We have been sealing commercial buildings since 2005.
For a smaller site near Castle Green, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Gaps in walls that were never built as compartment walls
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Signing off or certifying a building’s fire stopping
If you’re not sure, just phone 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Where we work in Castle Green
- Service gaps in risers
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Foam or ordinary sealant is never a fire-seal repair
- Keep product data and details in the fire safety file
- Arrange inspection before areas are covered up
- Ask which product is in place before decorating
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.
Common questions from Castle Green clients
Can you work at a site such as Goldsworth Park Trading Estate, by Castle Green?
Yes. Estates, retail parks and business parks around Castle Green, Goldsworth Park Trading Estate among them, are all within reach. To start, just ring 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Is Castle Green too far out for you?
No. Places such as Castle Green are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
What do you charge?
Every job gets its own fixed quote. To get one, call 01277 525 020 or email drawings and photos.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
What does an EI 60 rating mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested.
Do you approve fire stopping for building control?
No. Sign-off belongs to the designer or building control, not the installer. We will confirm the products and details used, and you can tell us what other records you need at quote stage.
Compartment walls and floors in Castle Green
At about 25 miles from central London, Castle Green is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
On a hospital site such as The Priory Hospital, which lies south-west of Castle Green, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. For a building such as Church of St Lawrence, new heating or data runs are the usual reason penetrations need sealing. Holiday works at schools like St Lawrence CofE (Aided) Primary School often leave service openings to seal before pupils return.

What else we do in Castle Green
How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking anything from one day to a planned run of visits, depending on the number of seals and the access. Rural sites near Castle Green may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- 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.
Before we start on site
- Warn occupants and staff about the work
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
