Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Check with the data sheet before painting over fire sealant
- Don’t let anyone top up a fire seal with the wrong product
- File the specified details where the next contractor can find them
- Make fire stopping part of every scope that crosses a fire-resisting wall
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
Fire stopping in Sibley's Green, done properly
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you are dealing with old intumescent sealant that has split away and seals disturbed by maintenance and left open, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Sibley's Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Sibley's Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

When to call us in Sibley's Green
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in.
Most enquiries start with something like this:
- Improvised or mixed-product fire seals
- Unsealed joints where partitions meet the slab
- Fire-rated sealant that has cracked or shrunk back
- Openings found when ceilings come down for a refit
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.
What your quote should include
- How they’ll work around occupants
- Health and safety accreditation such as CHAS
- Is the sealant right for the movement and the substrate?
- Their public liability cover

Common questions from Sibley's Green clients
What happens to BS 476 references for fire stopping in Sibley's Green?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
Is a smaller place like Sibley's Green outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can staff carry on working while you are here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Leave it or put it right?
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. Older rural buildings around Sibley's Green move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
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 fixed quote and we will explain how it’s made up.
