Fire stopping in Radlett
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you’re dealing with openings left by services added after handover and improvised or mixed-product fire seals, we can put it right, on service gaps in risers, cable penetrations and pipe penetrations alike. A single leaking joint is often how a building in Radlett first comes to us: we look at the rest while we’re there and tell you what we find.
Fire-rated sealing in a place like Radlett is normally a single building at a time. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email us and we’ll come back to it.

Fire-rated sealing for Radlett buildings
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. What we install is set by the specification, and it goes in to the tested detail. At about 16 miles from central London, Radlett is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.
In a school such as St John's Church of England Infant and Nursery School, fire-rated sealant goes in around service penetrations where it is specified. Older community buildings such as St John that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

What else we do in Radlett
Your questions answered
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Radlett?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Do you cover business parks and estates near Radlett, such as Otters Pool Way Industrial Estate?
Yes. Estates, retail parks and business parks around Radlett, Otters Pool Way Industrial Estate among them, are all within reach. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you work in Radlett?
Yes. Radlett is in our area and the rest of Hertfordshire, within our coverage of Greater London, South East England and Scotland. For a quote, speak to us on 01277 525 020 or send photos by email.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Can staff carry on working while you are here?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. If neighbouring businesses or buildings around Radlett need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Before we start on site
- Let building users know which areas are affected
- Tell us what induction or permit system the site runs
- Point out parking and an unloading spot

Advice
What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Signs you need fire stopping in Radlett
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.
Site and facilities staff are often the first to spot these:
- Non-fire-rated filler around services
- Snag lists that include open service penetrations
- Service penetrations left open after M&E works
- Openings found when ceilings come down for a refit
For a unit at a site such as Otters Pool Way Industrial Estate, 2.3 miles south-west of Radlett, new power or data runs between office and warehouse can breach a compartment wall.
What your quote should include
- Proof of insurance
- The terms of the workmanship guarantee
- Are they CHAS accredited or on Constructionline?
- How joint depth will be controlled
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Reviewing a building’s overall fire safety
- Issuing fire ratings or certificates for seals
- Gaps in walls that were never built as compartment walls
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think.
Joints and surfaces we work on
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
Surface by surface
Small ducts
Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.
