Fire stopping in Claygate Cross
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you have fire-rated sealant that has cracked or shrunk back and seals disturbed by maintenance and left open, we can put it right, on cable penetrations, linear gaps at wall heads and service gaps in risers alike. Facilities teams, main contractors and managing agents in Claygate Cross tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
A job near Claygate Cross is usually planned around one visit, 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.
A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email us and we will come back to it.

Signs you need fire stopping in Claygate Cross
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.
Things that usually lead to an enquiry:
- Openings left by services added after handover
- Fire-rated sealant that has cracked or shrunk back
- Unsealed penetrations discovered above suspended ceilings
- Builders’ foam or ordinary silicone in compartment walls
In a school such as Borough Green Primary School, fire-rated sealant goes in around service penetrations where it is specified.
Before you book anyone
- Will CSCS-carded applicators be on site?
- Their public liability cover
- Their pre-qualification and accreditations
- Which product they’ll use, and why it suits the joint
What happens if it’s left?
The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Around Claygate Cross, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

What the job involves on each surface
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.

FAQs: Claygate Cross
Is Claygate Cross off your patch?
Not at all. Claygate Cross is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What does the BS 476 change mean for fire-rated sealant in Claygate Cross?
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.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
How long does a typical visit take?
It depends on the scope, but the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Where services cross fire walls in Claygate Cross
Claygate Cross lies roughly 23 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting 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.
Offices at parks like Bourne Enterprise Centre, 1.3 miles to the north of Claygate Cross, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Hospital estates such as Sevenoaks Hospital, 5.1 miles to the west of Claygate Cross, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Claygate Cross is about 5 miles east of Sevenoaks, in Kent. Anywhere in TN15, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Claygate Cross is one of 931 places in Kent on our list for service penetrations. There’s a separate page for London, roughly 23 miles from Claygate Cross.

Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- File the specified details where the next contractor can find them
- Get seals inspected before ceilings and boxing close
- Foam or ordinary sealant is never a fire-seal repair
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.
