Fire stopping in South Norwood
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in South Norwood. If you have fire-rated sealant that has cracked or shrunk back and expanding foam used as fire stopping, we can put it right, on cable penetrations, linear gaps at wall heads and pipe penetrations alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in South Norwood it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Reviewing a building’s overall fire safety
- Gaps in walls that were never built as compartment walls
- Plastic pipes whose detail calls for a collar or wrap
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Questions we are asked in South Norwood
Will you work in a care home in South Norwood without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Does your area include sites such as Chaffinch Business Park, near South Norwood?
Yes. Our area takes in South Norwood and its surroundings, with estates and business parks such as Chaffinch Business Park included. Send details of the unit and the work through our quote form for a quick quote.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact.
Do you certify or sign off fire stopping?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.
What do BS EN 1366-3 and BS EN 13501-2 mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2. That rating only holds when the product is installed to its tested detail.
Different surfaces, different methods
Small ducts
We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Owners, agents and contractors
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in South Norwood can sit alongside others in a wider programme across Greater London.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Ask which product is in place before decorating
- Don’t let anyone top up a fire seal with the wrong product
- Record which product was used where
- Put resealing into every M&E and fit-out package
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there, not months later.
Our process
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. In South Norwood, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out first.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Let us know about inductions and permits
- Have the specification and drawings to hand
- Tell us which areas need to stay in use

Fire-rated sealing for South Norwood buildings
A good number of hotels sit less than 2 miles from South Norwood. 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. The 2 miles around South Norwood include five care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal.
Offices at parks like Chaffinch Business Park (1.1 miles east of South Norwood) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. For a site team at a college like Spurgeon's College (0.7 miles north-west of South Norwood), fire-rated sealing is best scheduled after the summer works. Shop fits in centres such as Whitgift Centre (to the south-west of South Norwood) can bring new services through fire-resisting walls between units, which then need the specified seal.
South Norwood is about 5 miles south-east of Stockwell, in Greater London. We cover commercial sites throughout South Norwood, for single jobs and planned programmes alike. South Norwood is one of 764 places in Greater London on our list. We also cover London, some 7 miles away.

When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
