How we handle fire stopping in Blendon
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. 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. We work on service gaps in risers, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are non-fire-rated filler around services and old intumescent sealant that has split away. Whoever orders the work in Blendon, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Maintenance after handover
Regular inspection catches problems early. In particular:
- Put resealing into every M&E and fit-out package
- Keep general-purpose fillers away from compartment walls
- Have penetrations checked while they can still be seen
- Report damaged or disturbed seals as soon as they’re spotted
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.

Leave it or put it right?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down. Failed sealant in a building in Blendon can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
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 quote and we’ll explain how it’s made up.

Where services cross fire walls in Blendon
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. We install whatever has been specified, to the product’s tested detail. With tenants changing and fit-outs following, London buildings see service routes altered again and again. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
On a site such as Old Bexley Business Park, which lies east of Blendon, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. At a university such as University of Greenwich Avery Hill Campus (1.9 miles west of Blendon), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a unit at a centre such as Broadway Shopping Centre, which lies north-east of Blendon, penetration seals are worth checking after each shop fit.

From enquiry to 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 we clear our waste as we work. In Blendon, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
What we need from you
- Have the specification and drawings to hand
- Tell staff and tenants when we will be in
- Make sure the joints can be reached
