Fire-rated sealant in Coney Hall, Greater London

Fire rated sealant in Coney Hall, done properly
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you are dealing with cracked or shrunken fire-rated sealant and gaps filled with a product that isn’t fire-rated, we can help, whatever the surface.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Where a building in Coney Hall needs to stay open, work can be planned outside normal hours.
Your job is guaranteed for a year, as with all our work.

What we are called out for in Coney Hall
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
People normally contact us after spotting one of these:
- Gaps left after a refit or conversion
- Door frames with gaps between frame and wall
- Gaps around pipes and cables through fire-resisting walls
- Fire stopping disturbed by later work
If you look after a church, hall or community building such as St Francis of Assisi, older buildings that have had new heating or wiring often have service gaps worth checking.
What your quote should include
- Who does the work, and how experienced they are
- Are they insured?
- The length of the guarantee
- Whether VAT is included

Leave it or put it right?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
Why us?

Fire rated sealant around Coney Hall
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Coney Hall is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Forest Academy, fire-stopping around service openings should be restored whenever new services go in.

Different surfaces, different methods
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point to make sure it suits the product.
How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. In Coney Hall, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
