Fire stopping in South Oxhey
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Surface by surface
Risers and ceiling voids
Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.
Metal pipes
Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.
About our fire stopping in South Oxhey
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around South Oxhey. If you are dealing with unsealed openings around new pipes and cables and non-fire-rated filler around services, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in South Oxhey, that means joint design, primers and backing rod as standard.
Converted and extended buildings around places like South Oxhey can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in South Oxhey
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
If one of these sounds familiar, it’s time for a closer look:
- Seals that don’t match their tested detail
- Builders’ foam or ordinary silicone in compartment walls
- Hidden openings found during inspections
- Unsealed openings around new pipes and cables
Halls and meeting rooms at places like Oxhey Chapel sometimes gain new services, and any compartment wall crossed needs the specified seal.

Fire stopping around South Oxhey: how the place shapes the job
South Oxhey is about 15 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of 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. Either way, we install the specified product to its tested detail.
At a college such as Harrow Weald College, 2.3 miles to the east of South Oxhey, checking penetration seals after summer M&E works is good practice. Where a unit on an estate such as Wiggenhall Industrial Estate, which lies north of South Oxhey, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
South Oxhey is about 2 miles north-west of Hatch End, in Hertfordshire. If you’re looking for fire stopping in South Oxhey, we can help, as we do across Hertfordshire. South Oxhey is one of 371 places we cover in Hertfordshire. Our London page has more on work in that area, about 15 miles away.

After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Brief every trade that openings they make must be sealed
- Keep product data and details in the fire safety file
- Check risers and ceiling voids after each round of works
- Settle who seals which penetrations at the start of a project
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.
Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Questions about South Oxhey
Will you plan work around the academic year at somewhere like Westminster University?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you take on a job at a hospital such as Watford General Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What does an EI 60 rating mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.
Will fire-rated sealant work on every penetration?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. Outside that, a different product is needed, as set out by the designer.
What do you charge?
Each job is quoted on its own details. For yours, phone 01277 525 020 or send photos by email.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
What sets the cost
These are the things that shape the price:
- The size and state of each joint
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
- The total length or number of joints
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- What the building is and how it’s used
- How the joints are reached, and at what height
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
How a job runs
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. What matters most for a job in South Oxhey is a clear list of what needs doing. You’ll then get a fixed price for the work.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Flag any permit to work we will need
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000
