About our fire stopping in Wicken Bonhunt
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Wicken Bonhunt. Most enquiries involve penetration schedules that need working through and unsealed penetrations discovered above suspended ceilings, across small duct penetrations where the tested detail allows, linear gaps at wall heads and pipe penetrations. Whoever orders the work in Wicken Bonhunt, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Barn and farm-building conversions near places like Wicken Bonhunt often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Why act early in Wicken Bonhunt
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Halls, stores and units around places like Wicken Bonhunt may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Penetration seals near Wicken Bonhunt
Wicken Bonhunt lies roughly 35 miles out 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. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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.
Holiday works at schools like Joyce Frankland Academy often leave service openings to seal before pupils return. Wherever services are added at a hospital such as Saffron Walden Community Hospital, 4.9 miles north-east of Wicken Bonhunt, the compartment line has to be made good with the specified product. Offices at parks like Funstons Commercial Centre (to the west of Wicken Bonhunt) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Keep general-purpose fillers away from compartment walls
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Check risers and ceiling voids after each round of works
- Keep product data and details in the fire safety file
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Writing the fire-stopping specification
- Fire doors, dampers or other fire safety equipment
- Walls or floors that aren’t fire-resisting to begin with
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think.

Wicken Bonhunt: questions and answers
What happens to BS 476 references for fire stopping in Wicken Bonhunt?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is Wicken Bonhunt 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. We plan jobs in smaller places so return trips are kept to a minimum.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
How the job changes by surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.
