About our fire rated sealant in Norwood End
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not 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 fire seals that have cracked with movement and holes left by a change of layout, we can help, whatever the surface.
Somewhere as small as Norwood End, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
Big or small, it’s backed by our one-year guarantee.

Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Openings too large for sealant, which need batts, boards or another system
- A wall that is not a fire-resisting element to begin with
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Pipe & cable gaps
- Service penetrations
- Door frames
- Plasterboard & masonry
- Linear gaps
- Flats & HMOs
Different surfaces, different methods
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist.
Flats and HMOs
Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product.
What fire rated sealant looks like in Norwood End
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.
Community buildings like Church of St Nicholas are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

When to call us in Norwood End
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service isn’t always sealed again.
Signs it’s time to call us include:
- Unsealed gaps where pipes and cables go through a wall
- Open joints along the top of partitions
- Damaged fire sealant left by other trades
- New service routes left unsealed after building work
Managing a site like The Ongar Academy? Then fire-stopping around service openings should be restored whenever new services go in.

Norwood End questions
Is Norwood End within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What guarantee comes with fire rated sealant in Norwood End?
All our work, in Norwood End and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you give us a record of the work?
Yes. We note each location and the product that went in so it’s there for the next inspection.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can you tell me how many minutes the seal will last?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What happens if it’s left?
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Where a wall is exposed, as many are in small places like Norwood End, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Looking after it afterwards
After the cure time, these simple habits help:
- Check whether a sealant can be painted before decorating over it
- Include hidden areas like risers in routine checks
- Take pictures of fire stopping before ceilings or boxing go back
- Keep general-purpose foam and caulk away from fire-stopping gaps
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
