Fire stopping in Old Coulsdon
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal rather than guesswork. We work on pipe penetrations, cable penetrations and service gaps in risers, and the failures we’re asked to look at most are openings left by services added after handover and hidden openings found during inspections. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Old Coulsdon is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a London area such as Old Coulsdon, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Common problems we fix in Old Coulsdon
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. Across several fit-outs, the openings add up.
What tends to prompt an enquiry:
- Service penetrations left open after M&E works
- Improvised or mixed-product fire seals
- Open linear gaps along the top of fire-resisting walls
- Fire-stopping items raised at inspection or handover
Industrial units on estates such as Ullswater Industrial Estate (1.4 miles north-west of Old Coulsdon) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Their approach to joint depth and backing
- The terms of the workmanship guarantee
- Their pre-qualification and accreditations
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. In Old Coulsdon, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Tell staff and tenants when we’ll be in
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000

Advice
Service penetrations in Old Coulsdon buildings
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 London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
In a school such as Keston Primary School, fire-rated sealant goes in around service penetrations where it is specified. In a building such as Church of St John the Evangelist, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Openings that need collars, wraps, batts or boards rather than sealant
- Fire doors, dampers or other fire safety equipment
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Pipe penetrations
General trades versus a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
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.
Questions about Old Coulsdon
Is hospital work, at somewhere like North Downs Hospital, something you do?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you take on jobs in Old Coulsdon where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Do you work in Scotland as well as England?
Building standards in Scotland are separate from England’s, while England relies on Approved Document B. Either way, we install the specified sealant to its tested detail.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we’ll set out a timescale with the quote.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Will you write the fire-stopping specification?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.
Leave it or put it right?
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. Failed sealant in a building in Old Coulsdon can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
