How we handle fire rated sealant in Wapping
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. If you’re dealing with open joints along the top of partitions and damaged fire sealant left by other trades, we can help, on flats & HMOs, linear gaps and door frames alike.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Wapping, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Big or small, you get the same 12-month guarantee in Wapping and across Greater London.

Fire rated sealant around Wapping
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. Wapping has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
For site and facilities teams at buildings such as St Mellitus College, service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Wapping station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as St Peter's, service openings in its walls need the right fire-rated sealant, as in any building.

Honest limits
It helps to know what we cannot do too:
- Problems with the door itself rather than the gap around the frame
- Deciding what fire stopping a building needs
- Big openings where sealant alone is not the tested solution

Surfaces we seal
- Door frames
- Flats & HMOs
- Linear gaps
- Service penetrations
- Pipe & cable gaps
- Plasterboard & masonry
Looking after it afterwards
After the cure time, these simple habits help:
- Photograph sealed gaps before they’re covered up
- File the fire-stopping record where your assessor can find it
- Include fire stopping when you schedule refits
- Keep general-purpose foam and caulk away from fire-stopping gaps
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

- Unsuitable material such as ordinary foam or silicone is cut out.

Advice
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Why it’s worth doing now in Wapping
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job that does not depend on other work. 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. Putting it right early is much less trouble.
Combining jobs into one visit normally makes better use of the time than several visits. We’ll give you a clear price for the lot.
