Surface by surface
Metal pipes
Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, with backing added if the detail requires it.
Fire stopping in Hither Green
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow. We work on joints between fire-resisting walls and floors, cable penetrations and small duct penetrations where the tested detail allows, and what we’re called in for most is hidden openings found during inspections and openings left by services added after handover. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hither Green, preparation and product choice get the time they need.
In a London area such as Hither Green, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email us and we’ll arrange a return visit.

Common questions from Hither Green clients
Will you work in a care home in Hither Green without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you approve fire stopping for building control?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.
Do you work in Hither Green?
Yes. Hither Green is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or email us.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Compartments and services around Hither Green
A 2-mile radius around Hither Green takes in a good number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We seal to the specification and the product’s tested detail, working within the building’s permits.
Colleges such as Christ the King Sixth Form College, 0.9 miles to the north of Hither Green, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Where a unit on an estate such as Chiltonian Industrial Estate, under half a mile to the south-east of Hither Green, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. In a retail centre such as Lewisham Shopping Centre, 0.9 miles north-west of Hither Green, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Writing the fire-stopping specification
- Construction that lacks the fire resistance the seal relies on
- Reviewing a building’s overall fire safety
If in doubt, call the office on 01277 525 020 or email us and we will say what we think before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Flag new cables with no seal around them
- Agree the fire-stopping specification before services go in
- Get seals inspected before ceilings and boxing close
- Foam or ordinary sealant is never a fire-seal repair
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match.
What happens if it’s left?
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme. Getting scaffold, permits or access booked in Hither Green takes effort, so it makes sense to deal with every failing joint while access is in place.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
