Fire stopping in Bexon, done properly
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 job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. We work on linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are service penetrations left open after M&E works and fire seals cut back for extra cables and never reinstated. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Bexon it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Rural conversions around Bexon can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
The 12-month guarantee covers our workmanship: 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.

For managing agents and facilities managers
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.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Bexon can form part of a wider programme.
Penetration seals near Bexon
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. Either way, we install the specified product to its tested detail. Bexon lies roughly 37 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.
Halls and meeting rooms at places like Church of St John the Baptist sometimes gain new services, and any compartment wall crossed needs the specified seal. On a hospital site such as Sittingbourne Memorial Hospital, 2.4 miles to the north-east of Bexon, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

When to call us in Bexon
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Typical triggers for a call:
- Fire-stopping items raised at inspection or handover
- Open linear gaps along the top of fire-resisting walls
- Fire-rated sealant that has cracked or shrunk back
- Seals that don’t match their tested detail
Offices at parks like Kent Science Park (to the north-east of Bexon) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. For work around Bexon, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Share your working hours and any access restrictions
- Let building users know which areas are affected
- Move anything stored against the joints

Common questions from Bexon clients
Can you work on a hospital site such as Sittingbourne Memorial Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Is Kent Science Park, near Bexon, within your area?
Yes, sites like Kent Science Park are within our area, along with the rest of Bexon. Photos and a short description are enough for a first look.
Are you members of a third-party fire-stopping installer scheme?
No. We don’t hold a third-party fire-stopping installer certificate. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we’re not the right fit for that package.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally 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.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Have penetrations checked while they can still be seen
- Check risers and ceiling voids after each round of works
- Check with the data sheet before painting over fire sealant
- Keep product data and details in the fire safety file
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there instead of being left for someone else.

Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter.
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Large openings beyond what any sealant detail covers
- Fire risk assessments, a job for a competent assessor
- Construction that lacks the fire resistance the seal relies on
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think before you book.
