How we handle fire rated sealant in Marlpit 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. Those are the gaps we close, using a tested fire-rated product. If you’re dealing with seals cut through by electricians, plumbers or data installers and gaps around pipes and cables through fire-resisting walls, we can help, whatever the surface.
Work in a small place like Marlpit Hill is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
There’s a 12-month guarantee on every job.

How the job changes by surface
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance to keep disruption down.
Your questions about fire rated sealant in Marlpit Hill
Is Marlpit Hill 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.
Do you work in hotels near Marlpit Hill?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Can ordinary silicone be used in a fire-stopping gap?
No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
What does intumescent mean?
An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do you need fire rated sealant in Marlpit Hill?
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.
Look out for any of the following:
- Unsealed gaps where pipes and cables go through a wall
- Open gaps behind door architraves
- Sealant items on a fire risk assessment action list
- Fire seals that have cracked with movement
For site and facilities teams at buildings such as Edenbridge Primary School, service openings in fire-resisting walls need checking after any refurbishment.

When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Assessing a building’s fire safety
- Openings too large for sealant, which need batts, boards or another system
- Issuing a fire rating or certificate for a building
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Pipe & cable gaps
- Flats & HMOs
- Door frames
- Service penetrations
- Plasterboard & masonry
- Linear gaps
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Get damaged fire seals looked at promptly
- Ask which product was used before you paint
- Include hidden areas like risers in routine checks
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
Commercial buildings in Marlpit 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, and gaps around services are often picked up there.

Hotel work can be planned room by room, with out-of-hours working where needed.
Letting a property close to Edenbridge station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Church of St Peter and St Paul are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What else we do in Marlpit Hill
What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. Around Marlpit Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
