- Unsealed gaps around fire door frames

Looking after it afterwards
Aftercare is simple:
- Include hidden areas like risers in routine checks
- Store the list of sealed gaps with your building paperwork
- Allow for resealing whenever new services are run
- Check whether a sealant can be painted before decorating over it
Tell other trades that the gaps have been sealed, 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 is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Fire rated sealant in Upper Norwood
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We work on pipe & cable gaps, flats & HMOs and door frames, and the jobs we see most are joints picked up in a fire-stopping survey and gaps filled with a product that isn’t fire-rated.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Upper Norwood, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Signs you need fire rated sealant in Upper Norwood
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Signs it’s time to call us include:
- Open gaps behind door architraves
- Standard silicone or caulk in a fire-stopping gap
- Gaps left after a refit or conversion
- Old fire sealant that has split or come away
If you let a flat or house near Gipsy Hill station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
What your quote should include
- Whether the sealant suits the joint
- Is VAT in the price?
- Is the old sealant removed completely?
- Which colour the sealant will be
For landlords and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Why deal with it now?
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we’ll tell you. 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.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Different surfaces, different methods
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist, and we’ll say if we spot a problem with them.
Workplaces and buildings in Upper Norwood
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.
Upper Norwood is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a church, hall or community building such as Christ Church, service openings in its walls need the right fire-rated sealant, as in any building.

The process
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. In a London area like Upper Norwood, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

Advice
Your questions about fire rated sealant in Upper Norwood
Is parking an issue for fire rated sealant in Upper Norwood?
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.
Can you help a landlord with a rental near Gipsy Hill station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Is intumescent sealant the same as fire-rated sealant?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
