Fire rated sealant for homes and businesses in Tulse Hill
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. If you’re dealing with damaged fire sealant left by other trades and sealant items on a fire risk assessment action list, we can put it right, whatever the surface.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Tulse Hill cannot close.
Each job carries a 12-month guarantee, large or small.

What else we do in Tulse Hill
Leave it or put it right?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Workplaces and buildings in Tulse Hill
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. 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 work to the specification you’re given, installing the product to its tested details.
If you let a flat or house near Tulse Hill station, any gap left by new services in shared walls should be closed with a fire-rated product. As a London address, Tulse Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

Do you need fire rated sealant in Tulse Hill?
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.
Signs it’s time to call us include:
- Fire stopping disturbed by later work
- Gaps where walls meet ceilings or slabs
- Holes left by a change of layout
- Ordinary sealant used where a fire-rated product was needed
If you look after a church, hall or community building such as Holy Trinity Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.
Can you fill the gap behind a fire door frame?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door, its seals and closer are for a door specialist.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Are you insured?
Yes. We’re fully insured.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
