Fire rated sealant in Millwall: local notes
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. Millwall has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
As a London address, Millwall can be tricky for parking: let us know about parking bays, permits or a driveway. For landlords with property near Deptford station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Fire rated sealant in Millwall, done properly
We often work from an action list drawn up by a fire risk assessor for buildings in Millwall. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. If you are dealing with gaps around pipes and cables through fire-resisting walls and sealant items on a fire risk assessment action list, 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 Millwall, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

- The old material and how stubborn it is
- The number and length of the joints
- The number of rooms or windows
- Mould in or behind the old joints
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

To make quoting easier, please include:
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height

Surface by surface
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
FAQs for Millwall
Is parking an issue for fire rated sealant in Millwall?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Deptford station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you come to Millwall?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Do you have insurance?
Yes. Full insurance covers our work.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
What information do you need?
A short description and the location. We will ask anything else we need to know.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Why deal with it now?
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Millwall, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Honest limits
Before booking, it’s worth knowing the limits too:
- Openings too large for sealant, which need batts, boards or another system
- Fire risk assessments, which need a qualified assessor
- Fire doors that need new seals, closers or hardware
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Flats & HMOs
- Plasterboard & masonry
- Pipe & cable gaps
- Service penetrations
- Door frames
- Linear gaps
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Check risers, ceiling voids and cupboards during building checks
- Flag any open gap you spot round a pipe or cable
- Do not paint over fire sealant until it has cured
- Do not fill fire-stopping gaps with ordinary foam or silicone
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
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.
The process
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work 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.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
Getting ready for the visit
- Clear the area around the work
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

What we’re called out for in Millwall
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
Look out for these signs:
- Seals cut through by electricians, plumbers or data installers
- Unsealed gaps where pipes and cables go through a wall
- New service routes left unsealed after building work
- Standard silicone or caulk in a fire-stopping gap
Community buildings like Church of St Nicholas are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
