About our fire stopping in Radwinter
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about expanding foam used as fire stopping and seals disturbed by maintenance and left open, on linear gaps at wall heads, cable penetrations and joints between fire-resisting walls and floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Radwinter is the same: the right product in a properly prepared joint.
A job near Radwinter is usually planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Location, for remote and island sites
- Backing rod, priming and other preparation
- Which sealant the job calls for
- Whether old sealant has to be cut out first
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Your programme or deadline
- A wide shot and a close-up of the area
- Any specification or named product
- Access details, including height
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.
Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Jobs in and around smaller places like Radwinter are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Have the specification and drawings to hand
- Move anything stored against the joints
- Flag any permit to work we will need
Quotes
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send details through our quote form.

What else we do in Radwinter
Your questions answered
Is a hospital such as Saffron Walden Community Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What happens to BS 476 references for fire stopping in Radwinter?
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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
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.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.
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. Older rural buildings around Radwinter move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Owners, agents and contractors
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Signs you need fire stopping in Radwinter
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position, so it has to come out.
Look out for the following:
- Improvised or mixed-product fire seals
- Penetration schedules that need working through
- Old intumescent sealant that has split away
- Open linear gaps along the top of fire-resisting walls
Large healthcare estates like Saffron Walden Community Hospital (to the west of Radwinter) change their services often, so penetration seals are worth checking after M&E work.
What your quote should include
- Is the sealant right for the movement and the substrate?
- Health and safety accreditation such as CHAS
- Their public liability cover
- Whether their applicators hold CSCS cards
Compartment walls and floors in Radwinter
At about 40 miles from central London, Radwinter is within reach of the capital. 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. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
In a building such as Church of St Mary the Virgin, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a school such as Radwinter Church of England Voluntary Aided Primary School, penetration sealing fits best at the end of the summer works.
