What we are called out for in Duton Hill
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Most enquiries start with something like this:
- Hidden openings found during inspections
- Snag lists that include open service penetrations
- Improvised or mixed-product fire seals
- Fire sealant pulled out of the opening
For a building such as Church of St Mary the Virgin, new heating or data runs are the usual reason penetrations need sealing.

- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Do they follow the manufacturer’s priming guidance?
- Can the work be phased to keep areas open?
- Will RAMS and insurance details be available?
How we handle fire stopping in Duton Hill
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. Most enquiries involve fire sealant pulled out of the opening and openings found when ceilings come down for a refit, on pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors. Facilities teams, main contractors and managing agents in Duton Hill tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller places such as Duton Hill still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Halls, stores and units around places like Duton Hill may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
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 and we will explain how it’s made up.

Common questions from Duton Hill clients
What does the BS 476 change mean for fire-rated sealant in Duton Hill?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is Duton Hill too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does the weather affect the work?
It can, when the joints are outside. 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. Internal work is far less affected.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What do you charge?
Each job is quoted on its own details. To get one, call 01277 525 020 or email drawings and photos with a description of the work.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
What sets the cost
The price varies from site to site. It mainly depends on:
- Joint width, depth and condition
- How much there is to seal
- Distance, for remote addresses
- Working within restricted access windows
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.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- The site address and postcode
- Clear photos of the problem areas
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, speak to us on 01277 525 020 or email the details over.
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Brief every trade that openings they make must be sealed
- Agree the fire-stopping specification before services go in
- Include service cupboards in routine inspections
- Keep product data and details in the fire safety file
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.
Fire-rated sealing for Duton Hill buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Either way, we install the specified product to its tested detail. Duton Hill lies roughly 34 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Office fit-outs on sites such as Williams Field Business Centre, 1.9 miles to the west of Duton Hill, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Schools such as Putteridge High School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Our process
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Duton Hill can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- 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.
Getting the site ready
- Explain the parking and delivery arrangements
- Flag any permit to work we will need
- Make sure the joints can be reached
Ask for a quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

What the job involves on each surface
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, with backing added if the detail requires it.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.
