Fire stopping in Stanwell: the local picture
Stanwell lies roughly 17 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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.
In a hotel such as The Stanwell Hotel, which lies north-west of Stanwell, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Colleges such as Brooklands College - Ashford Campus (1 mile south of Stanwell) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Stanwell is about 2 miles north of Ashford, in Surrey. Anywhere in TW19, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Surrey coverage takes in 379 places, large and small. Our London page has more on work in that area, about 17 miles away.

How we handle fire stopping in Stanwell
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. 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, service gaps in risers and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are fire-rated sealant that has cracked or shrunk back and open linear gaps along the top of fire-resisting walls. Whether you call it commercial sealant work, mastic application or joint sealing, in Stanwell it comes down to the same thing: the right product in a properly prepared joint.
Buildings in a smaller place such as Stanwell that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

Common questions from Stanwell clients
Can you work around term dates at a campus such as Royal Holloway University?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on work at healthcare sites like Ashford Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details. We can follow the services contractor floor by floor keeping pace with the programme.
What does an EI 60 rating mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2. That rating only holds when the product is installed to its tested detail.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Can you seal any opening with fire-rated sealant?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.
After the work
For the best life from the joints:
- Keep product data and details in the fire safety file
- Keep general-purpose fillers away from compartment walls
- Check with the data sheet before painting over fire sealant
- Settle who seals which penetrations at the start of a project
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
Cost factors for service penetrations
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Removal of failed or old sealant
- Quantities, in metres or numbers
- Backing rod, priming and other preparation
- Access and working height
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
- The product your specification calls for
- The type of building and who uses it
To get a fixed quote, call the office on 01277 525 020 or send details through our quote form. You can also send details through our quote form.
Signs you need fire stopping in Stanwell
Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Most enquiries start with one or more of the following:
- Builders’ foam or ordinary silicone in compartment walls
- Fire sealant pulled out of the opening
- Fire-stopping items raised at inspection or handover
- Hidden openings found during inspections
Where a unit on an estate such as Westgate Industrial Estate, which lies south-east of Stanwell, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Comparing quotes
- How long is the guarantee, and what does it include?
- Which product they’ll use, and why it suits the joint
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Do they follow the manufacturer’s priming guidance?

What else we do in Stanwell
General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Our process
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 any cutting starts, 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. For a site in Stanwell, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Point out any areas we must not close
- Share the asbestos register for older buildings
- Tell us what induction or permit system the site runs

Advice
How the job changes by surface
Small ducts
We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.
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 the installation has to fit inside those limits.
