About our fire rated sealant in Crofton Park
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We work on door frames, service penetrations and plasterboard & masonry, and the jobs we see most are standard silicone or caulk in a fire-stopping gap and open joints along the top of partitions.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Crofton Park, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours for a handful of gaps, and longer for a whole building. For a job in Crofton Park, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

Why act early in Crofton Park
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. 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 Crofton Park, the repair is bigger than the sealant job would have been.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

Can you fill the gap behind a fire door frame?
Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door leaf and its hardware need a door specialist.
How much does fire rated sealant cost in Crofton Park?
Size, access and the old material all affect the cost. Ask us for a quote.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated to help seal the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Honest limits
A few problems are outside what sealant work can do:
- Problems with the door itself rather than the gap around the frame
- Issuing a fire rating or certificate for a building
- Construction that does not provide fire resistance on its own
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.

- Pipe & cable gaps
- Service penetrations
- Door frames
- Linear gaps
- Plasterboard & masonry
- Flats & HMOs
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Never patch a fire seal with standard sealant
- Flag any open gap you spot round a pipe or cable
- Check risers, ceiling voids and cupboards during building checks
- Tell trades working in the building that fire seals must be put back
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 job gets bigger.
Workplaces and buildings in Crofton Park
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Schools such as Stillness Infant School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. As a London address, Crofton Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Crofton Park station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What the job involves on each surface
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail.
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
