When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Reviewing a building’s overall fire safety
- Walls or floors that aren’t fire-resisting to begin with
- Plastic pipes whose detail calls for a collar or wrap

How we handle fire stopping in Owlsmoor
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Owlsmoor. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and service gaps in risers, and the failures we’re asked to look at most are seals disturbed by maintenance and left open and fire stopping installed outside its tested range.

Different surfaces, different methods
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
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.
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a job in Owlsmoor, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- 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.
What we need from you
- Tell us your opening times and when work is allowed
- Tell staff and tenants when we will be in
- Tell us what induction or permit system the site runs

Advice
Your questions answered
What happens to BS 476 references for fire stopping in Owlsmoor?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is a hospital such as Broadmoor Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Do you need fire stopping in Owlsmoor?
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
It’s worth sending us details if you spot any of the following:
- Hidden openings found during inspections
- Seals disturbed by maintenance and left open
- Fire sealant pulled out of the opening
- Unsealed joints where partitions meet the slab
Tenant changes at parks like Wellington Business Park, 1.5 miles west of Owlsmoor, bring new data and services, and openings through fire-resisting walls need the specified seal.
Comparing quotes
- Whether their applicators hold CSCS cards
- Do they follow the manufacturer’s priming guidance?
- Their approach to joint depth and backing
- Can the work be phased to keep areas open?
Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. For buildings in places like Owlsmoor, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Compartment walls and floors in Owlsmoor
For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. The area within 2 miles of Owlsmoor holds a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Wherever services are added at a hospital such as Broadmoor Hospital, 0.8 miles north of Owlsmoor, the compartment line has to be made good with the specified product. Hotels such as Dial House Hotel (to the north-west of Owlsmoor) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

We can often quote from photographs and a few details. Please tell us:
