Fire stopping for Henwood sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How the job changes by surface
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Fire stopping for commercial buildings in Henwood
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on cable penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we are called in for most is seals that don’t match their tested detail and non-fire-rated filler around services. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Henwood it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Barn and farm-building conversions near places like Henwood often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Check risers and ceiling voids after each round of works
- Ask which product is in place before decorating
- Arrange inspection before areas are covered up
- Keep product data and details in the fire safety file
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match.
Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Plastic pipes whose detail calls for a collar or wrap
- Fire doors, dampers or other fire safety equipment
If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
What we’re called out for in Henwood
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.
These are often picked up first by site or facilities staff:
- Seals that don’t match their tested detail
- Fire-rated sealant that has cracked or shrunk back
- Snag lists that include open service penetrations
- Builders’ foam or ordinary silicone in compartment walls
Older community buildings such as Church of St Peter that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Questions to ask before you book
- Their public liability cover
- Their pre-qualification and accreditations
- How they handle RAMS and site documents
- How the joint faces will be prepared and primed
What sets the cost
Before we quote, we look at:
- Working within restricted access windows
- Travel to remote or island sites
- How much existing material needs removing
- The site’s rules and procedures
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Send us:
- A wide shot and a close-up of the area
- Your programme or deadline
- The asbestos register, for older buildings
- Anything awkward about access or site hours
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email a schedule or drawings.
Common questions from Henwood clients
How does the move away from BS 476 affect penetration seals in Henwood?
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.
Will you work in a care home in Henwood without moving residents out?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months.

How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. Jobs in and around smaller places like Henwood are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed
- Warn occupants and staff about the work
Ask for a quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
