About our fire rated sealant in Botany Bay
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. We work on flats & HMOs, plasterboard & masonry and door frames, and common reasons people get in touch are standard silicone or caulk in a fire-stopping gap and gaps flagged on a fire risk assessment.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Botany Bay, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Your job is guaranteed for a year, as with all our work.

Why act early in Botany Bay
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Botany Bay, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look in service cupboards and ceiling voids from time to time
- Allow for resealing whenever new services are run
- Get damaged fire seals looked at promptly
- Make resealing part of every contractor’s brief
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.
What fire rated sealant looks like in Botany Bay
Commercial buildings in London often have strict access rules and limited loading, 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.
Rented homes near Crews Hill station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. For site and facilities teams at buildings such as St. John's Senior School, service openings in fire-resisting walls need checking after any refurbishment.

When to call us in Botany Bay
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
Common reasons people contact us are:
- Standard silicone or caulk in a fire-stopping gap
- Fire seals that have cracked with movement
- New service routes left unsealed after building work
- Open holes round services passing through fire walls
As a London address, Botany Bay can be tricky for parking: let us know about parking bays, permits or a driveway.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
