Fire stopping in Broad Colney, done properly
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance in Broad Colney and nearby. If you have expanding foam used as fire stopping and unsealed penetrations discovered above suspended ceilings, we can put it right, on linear gaps at wall heads, pipe penetrations and joints between fire-resisting walls and floors alike. Most enquiries from Broad Colney start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Broad Colney, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
A 12-month guarantee applies to all our work in Hertfordshire. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we will come back to it.

FAQs: Broad Colney
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Broad Colney?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Could you schedule work at a campus like University of Hertfordshire for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Do you cover Broad Colney?
Yes. We cover Broad Colney, and the simplest way to start is to speak to us on 01277 525 020 or email a schedule or drawings.

Penetration seals near Broad Colney
Central London is about 17 miles from Broad Colney. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
For a unit at a site such as Colney Fields Shopping Park, 0.6 miles east of Broad Colney, any new service through a fire-resisting wall should be sealed to the tested detail. Halls and meeting rooms at places like Church of St Peter sometimes gain new services, and any compartment wall crossed needs the specified seal.

Different surfaces, different methods
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area and tell you about openings outside the list.
What sealant work can’t fix
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Approving the work on behalf of building control
- Reviewing a building’s overall fire safety
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think.
What we seal
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
Common problems we fix in Broad Colney
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.
Any of the following is a good reason to get the joints checked over:
- Seals disturbed by maintenance and left open
- Expanding foam used as fire stopping
- Fire sealant pulled out of the opening
- Seals that don’t match their tested detail
Wherever services are added at a hospital such as Kingsley Green Hospital, 0.8 miles to the south-west of Broad Colney, the compartment line has to be made good with the specified product.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- What level of public liability insurance do they hold?
- Who will actually carry out the work
- How they’ll work around occupants

Why it’s worth doing now in Broad Colney
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Halls, stores and units around places like Broad Colney may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
