Fire stopping in Longwick, done properly
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. Site teams most often ask us about seals that don’t match their tested detail and unsealed openings around new pipes and cables, on pipe penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows. Looking for mastic applicators who cover Longwick? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
In places the size of Longwick, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Fire stopping in Longwick: the local picture
Longwick is about 37 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. 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. What we install is set by the specification, and it goes in to the tested detail.
In a school such as Longwick Church of England Combined School, fire-rated sealant goes in around service penetrations where it is specified. Theatres, wards and plant rooms at sites like The Paddocks Hospital, 1.6 miles east of Longwick, all have compartment walls crossed by services.

Longwick: questions and answers
Is a smaller place like Longwick outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
What happens to BS 476 references for fire stopping in Longwick?
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.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
After the work
For the best life from the joints:
- Don’t let anyone top up a fire seal with the wrong product
- Look above ceilings when tiles are lifted for other jobs
- Check with the data sheet before painting over fire sealant
- Brief every trade that openings they make must be sealed
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there, not months later.

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 we will confirm the paperwork you need with the quote.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Deciding what a wall or floor needs, which belongs to the designer
- Large openings beyond what any sealant detail covers
- Issuing fire ratings or certificates for seals
If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.
What we seal
- Service gaps in risers
- Pipe penetrations
- Linear gaps at wall heads
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
When to call us in Longwick
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Most enquiries start with something like this:
- Penetration schedules that need working through
- Openings left by services added after handover
- Open linear gaps along the top of fire-resisting walls
- Hidden openings found during inspections
Older community buildings such as Owlswick Chapel 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
- Proof of insurance
- How long is the guarantee, and what does it include?
- How they’ll work around occupants
- How they handle RAMS and site documents
