About our fire stopping in Warren Corner
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. We close the openings listed on your schedule, using the specified sealant and detail. We work on small duct penetrations where the tested detail allows, cable penetrations and linear gaps at wall heads, and what we’re called in for most is seals that don’t match their tested detail and snag lists that include open service penetrations. Whoever orders the work in Warren Corner, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A job near Warren Corner is typically planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
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.

Maintenance after handover
After handover, these steps help:
- Keep product data and details in the fire safety file
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Leave fire sealant to cure fully before covering it
- Foam or ordinary sealant is never a fire-seal repair
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.

What sets the cost
Quotes vary with the job. Expect it to depend on:
- Location, for remote and island sites
- Phasing around occupants
- The product specified
- Whether old sealant has to be cut out first
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
What we need to price the job
A few photographs plus some basic facts will normally do. It helps to include:
- Where the site is, with the postcode
- Whether an asbestos survey exists
- Access details, including height
- When you need the work done
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
FAQs: Warren Corner
What happens to BS 476 references for fire stopping in Warren Corner?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Would you work within a site like Spire Clare Park 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.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What do you charge?
There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Rural sites near Warren Corner may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Before we start on site
- Confirm the product named in the specification
- Tell staff and tenants when we’ll be in
- Flag any permit to work we will need

Compartment walls and floors in Warren Corner
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. What we install is set by the specification, and it goes in to the tested detail. Central London is about 37 miles from Warren Corner. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.
Office fit-outs on sites such as Fleet Business Park, 1.4 miles to the north of Warren Corner, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. For a hospital such as Spire Clare Park Hospital, 0.9 miles to the south-west of Warren Corner, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. For a building such as St Mary's Church, new heating or data runs are the usual reason penetrations need sealing.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Gaps in walls that were never built as compartment walls
- Signing off or certifying a building’s fire stopping
- Reviewing a building’s overall fire safety
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Surfaces we seal
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads

Leave it or put it right?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. Halls, stores and units around places like Warren Corner may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
