Fire stopping in Birch, done properly
Facilities managers in Birch often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. We work on joints between fire-resisting walls and floors, service gaps in risers and pipe penetrations, and the usual reasons a site gets in touch are damaged fire seals in risers and voids and unsealed penetrations discovered above suspended ceilings. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Birch is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Birch, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Your questions answered
What happens to BS 476 references for fire stopping in Birch?
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 hospital such as Essex County Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Flag new cables with no seal around them
- Have penetrations checked while they can still be seen
- Record which product was used where
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Older rural buildings around Birch move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

What else we do in Birch
When to call us in Birch
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, 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.
Any of the following is a good reason to get the joints checked over:
- Service penetrations left open after M&E works
- Fire seals cut back for extra cables and never reinstated
- Snag lists that include open service penetrations
- Old intumescent sealant that has split away
In a school such as Birch Church of England Voluntary Aided Primary School, fire-rated sealant goes in around service penetrations where it is specified.

How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Birch are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- 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.
Getting the site ready
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints
- Share your working hours and any access restrictions
