Fire stopping in Great Bardfield
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about openings found when ceilings come down for a refit and head-of-wall gaps with no fire seal, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and service gaps in risers. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Great Bardfield, preparation and product choice get the time they need.
Rural conversions around Great Bardfield can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How a job runs
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Great Bardfield may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Clear stock, furniture or equipment away from the joints
- Point out parking and an unloading spot

What the job involves on each surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork typically needs a different solution set by the designer and we flag that rather than guess.
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail.
When to call us in Great Bardfield
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.
Any of the following is a good reason to get the joints checked over:
- Unsealed openings around new pipes and cables
- Improvised or mixed-product fire seals
- Expanding foam used as fire stopping
- Snag lists that include open service penetrations
In a building such as Parish Church of St Mary the Virgin, any service penetration through a fire-resisting wall should be sealed to the specified detail.
What your quote should include
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?
- How the existing material will be dealt with
FAQs: Great Bardfield
What happens to BS 476 references for fire stopping in Great Bardfield?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is Great Bardfield off your patch?
Not at all. Great Bardfield is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Leave it or put it right?
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. Halls, stores and units around places like Great Bardfield may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Looking after the joints
Regular inspection catches problems early. Specifically:
- Treat an open penetration as a priority repair
- Agree the fire-stopping specification before services go in
- Keep product data and details in the fire safety file
- Put resealing into every M&E and fit-out package
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
Fire stopping in Great Bardfield: the local picture
Approved Document B is the English guidance that covers fire stopping around openings and penetrations.

Our part stays the same: the specified product, installed to its tested detail. At about 38 miles from central London, Great Bardfield is within reach of the capital.

Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
