About our fire rated sealant in Biggin Hill
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. 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. Typical jobs include cracked or shrunken fire-rated sealant and door frames with gaps between frame and wall, across linear gaps, service penetrations and door frames.
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 Biggin Hill, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Each job carries a 12-month guarantee, whatever its size.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make resealing part of every contractor’s brief
- Check risers, ceiling voids and cupboards during building checks
- Photograph sealed gaps before they’re covered up
- Report cracked or damaged seals as soon as you notice them
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t and we’ll tell you which one you have.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Doors that aren’t fire doors in the first place
- Sign-off of the building, which sits with building control or your assessor
- Construction that does not provide fire resistance on its own
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Linear gaps
- Pipe & cable gaps
- Flats & HMOs

Workplaces and buildings in Biggin Hill
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
If you look after a building such as Oaklands Primary Academy, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St Mark's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. As a London address, Biggin Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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 does not work out, we can still put it right.
Surface by surface
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail and we’ll flag it.
Why deal with it now?
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. Converted houses in London often have a bathroom above someone else’s living room, 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.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear price before we start.

In total, it generally takes from a few hours to a few days, depending on the number of gaps and the access. In Biggin Hill, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
