Questions we are asked in Blackgang
What happens to BS 476 references for fire stopping in Blackgang?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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 smaller place like Blackgang outside your area?
No. Places such as Blackgang are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
About our fire stopping in Blackgang
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. We work on joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads, and the failures we are asked to look at most are snag lists that include open service penetrations and fire sealant pulled out of the opening. Most enquiries from Blackgang start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Smaller places such as Blackgang still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What happens if it’s left?
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Around Blackgang, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
Why us?
- Fixed quotes based on photographs, drawings or a visit
- CHAS accredited contractor
- 12 months’ guarantee on every job
- Work carried out by CSCS-carded applicators

When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Walls or floors that aren’t fire-resisting to begin with
- Large openings beyond what any sealant detail covers
- Issuing fire ratings or certificates for seals
Not sure which it is? You can phone 01277 525 020 or send photos by email and we will tell you honestly before you book.
Surfaces we seal
- Service gaps in risers
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
How the job changes by surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products.
Risers and ceiling voids
Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.
Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
What we’re called out for in Blackgang
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Typical triggers for a call:
- Hidden openings found during inspections
- Fire seals cut back for extra cables and never reinstated
- Seals that don’t match their tested detail
- Service penetrations left open after M&E works
Large healthcare estates like Whitecroft Hospital, 5.7 miles north of Blackgang, change their services often, so penetration seals are worth checking after M&E work.
Comparing quotes
- Can the work be phased to keep areas open?
- Whether primer will be used where the manufacturer specifies it
- Is the sealant right for the movement and the substrate?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Compartments and services around Blackgang
For England, the fire stopping of penetrations is dealt with in 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. Our part stays the same: the specified product, installed to its tested detail.
Halls and meeting rooms at places like St Andrew's Church sometimes gain new services, and any compartment wall crossed needs the specified seal. Schools such as Niton Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
