About our fire rated sealant in East Sheen
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. If you have ordinary sealant used where a fire-rated product was needed and gaps where walls meet ceilings or slabs, we can help, whatever the surface.
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 East Sheen, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
All of our work is guaranteed for twelve months, in East Sheen and everywhere else we cover.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Fire doors that need new seals, closers or hardware
- Openings too large for sealant, which need batts, boards or another system
- Construction that does not provide fire resistance on its own
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

What fire rated sealant looks like in East Sheen
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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
If you let a flat or house near Mortlake station, any gap left by new services in shared walls should be closed with a fire-rated product. East Sheen is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Signs you need fire rated sealant in East Sheen
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
The problems people usually mention when they call are:
- Standard silicone or caulk in a fire-stopping gap
- Damaged fire sealant left by other trades
- Cracked or shrunken fire-rated sealant
- Holes left by a change of layout
Schools such as Thomson House School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes anything from a few hours to several days, depending on how many gaps there are. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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, then guaranteed for a year.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Store the list of sealed gaps with your building paperwork
- Never patch a fire seal with standard sealant
- Do not paint over fire sealant until it has cured
- Look in service cupboards and ceiling voids from time to time
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. 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. Putting it right early is much less trouble for homes in East Sheen.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
