Questions we’re asked in Stanmore
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Stanmore?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is Stanmore too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Can the building stay open while you work?
Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
What will the job cost?
Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or email a schedule or drawings with a description of the work.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
About our fire stopping in Stanmore
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. Most enquiries involve old intumescent sealant that has split away and hidden openings found during inspections, across small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads. A specialist sealant contractor works differently from a general builder: in Stanmore, that means joint design, primers and backing rod as standard.
Barn and farm-building conversions near places like Stanmore often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email us and we will come back to it.

Advice
When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Signing off or certifying a building’s fire stopping
- Plastic pipes whose detail calls for a collar or wrap
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think before you book.
Surfaces we seal
- Service gaps in risers
- Linear gaps at wall heads
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
Fire stopping in Stanmore: the local picture
At about 52 miles from central London, Stanmore is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail.
In a building such as Church of St Nicholas, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What we’re called out for in Stanmore
Openings in fire-resisting walls usually appear when services are added or changed. 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. Over a few years of fit-outs, a wall can collect a lot of these.
Clients normally get in touch after noticing one or more of the following:
- Unsealed joints where partitions meet the slab
- Openings left by services added after handover
- Builders’ foam or ordinary silicone in compartment walls
- Fire seals cut back for extra cables and never reinstated
Schools such as Beedon C.E. (Controlled) Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
Questions to ask before you book
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How long is the guarantee, and what does it include?
- The named product and why it was chosen
- Health and safety accreditation such as CHAS
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Look above ceilings when tiles are lifted for other jobs
- Leave fire sealant to cure fully before covering it
- Don’t let anyone top up a fire seal with the wrong product
- Record which product was used where
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.
What the job involves on each surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
