Fire stopping for commercial buildings in Burnham Green
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. What we bring is careful installation of the specified sealant, to the maker’s guidance. We work on linear gaps at wall heads, service gaps in risers and cable penetrations, and the usual reasons a site gets in touch are service penetrations left open after M&E works and hidden openings found during inspections. Looking for mastic applicators who cover Burnham Green? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Barn and farm-building conversions near places like Burnham Green 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: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Put resealing into every M&E and fit-out package
- Ask which product is in place before decorating
- Arrange inspection before areas are covered up
- Report damaged or disturbed seals as soon as they’re spotted
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Walls or floors that aren’t fire-resisting to begin with
- Issuing fire ratings or certificates for seals
- Deciding what a wall or floor needs, which belongs to the designer
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly before you book.

Your questions answered
Do you cover business parks and estates near Burnham Green, such as Little Ridge Industrial Estate?
Yes, sites like Little Ridge Industrial Estate are within our area, along with the rest of Burnham Green. Photos and a short description are enough for a first look.
Is Burnham Green off your patch?
Not at all. Burnham Green is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you hold third-party fire-stopping installer certification?
No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we’ll say so straight away rather than waste your time.
Is the BS 476 change in 2029 relevant to fire stopping?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, though transitional rules apply. Scotland follows its own Technical Handbook, with clause 2.1.14 covering service penetrations.
Is the work guaranteed?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. Converted and older buildings near places like Burnham Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Fire stopping of openings and penetrations in England falls under Approved Document B.

How the job changes by surface
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness first.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
Diagnose, treat, sign off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Jobs in and around smaller places like Burnham Green are typically planned as a single visit, so photos and measurements up front really help. 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Let us know about inductions and permits
- Let building users know which areas are affected
- Share the asbestos register for older buildings
