Fire stopping across Riverhead
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Work in places the size of Riverhead is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance
- Send your site hours and access windows

Fire stopping for commercial buildings in Riverhead
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Site teams most often ask us about service penetrations left open after M&E works and unsealed penetrations discovered above suspended ceilings, on cable penetrations, linear gaps at wall heads and service gaps in risers. A single leaking joint is often how a building in Riverhead first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Buildings in a smaller place such as Riverhead that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Approving the work on behalf of building control
- Large openings beyond what any sealant detail covers
- Fire risk assessments, a job for a competent assessor
Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
Surfaces we seal
- Cable penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Pipe penetrations
After the work
Once the work is signed off, these steps help:
- Foam or ordinary sealant is never a fire-seal repair
- Have penetrations checked while they can still be seen
- Report damaged or disturbed seals as soon as they’re spotted
- Settle who seals which penetrations at the start of a project
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.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.
What we are called out for in Riverhead
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
Look out for the following:
- Hidden openings found during inspections
- Fire-rated sealant that has cracked or shrunk back
- Head-of-wall gaps with no fire seal
- Unsealed openings around new pipes and cables
Schools such as Amherst School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
- What level of public liability insurance do they hold?
- Will RAMS and insurance details be available?

Compartments and services around Riverhead
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail. At about 19 miles from central London, Riverhead is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Hospital estates such as Sevenoaks Hospital (to the east of Riverhead) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing.
