Fire stopping for Westcott sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Fire stopping in Westcott
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. If you’re dealing with expanding foam used as fire stopping and hidden openings found during inspections, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Westcott it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A job near Westcott is normally planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to call us in Westcott
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
If one of these sounds familiar, it’s time for a closer look:
- Builders’ foam or ordinary silicone in compartment walls
- Fire-rated sealant that has cracked or shrunk back
- Improvised or mixed-product fire seals
- Seals disturbed by maintenance and left open
In a hotel such as The Bell Hotel, which lies east of Westcott, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Questions about Westcott
Can you seal around new services in a hotel near Westcott?
Yes. We install fire-rated and intumescent sealant where it is specified. 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 Westcott?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
Where services cross fire walls in Westcott
For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail. The area within 2 miles of Westcott holds several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
Schools such as Surrey Hills All Saints Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Older community buildings such as St John's Community Hall that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Westcott is about 2 miles west of Dorking, in Surrey. Our applicators travel to Westcott for work on service penetrations. 379 places across Surrey fall within our area, including Westcott. There’s a separate page for London, about 22 miles away.

Looking after the joints
Regular inspection catches problems early. In particular:
- Agree the fire-stopping specification before services go in
- Record which product was used where
- Arrange inspection before areas are covered up
- Leave fire sealant to cure fully before covering it
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
Different surfaces, different methods
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.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. Jobs in and around smaller places like Westcott are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Move anything stored against the joints
- Send your site hours and access windows
- Send any specification or drawings in advance

When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Large openings beyond what any sealant detail covers
- Fire risk assessments, a job for a competent assessor
- Approving the work on behalf of building control
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

What happens if it’s left?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Halls, stores and units around places like Westcott may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
