Fire stopping in Three Chimneys, done properly
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 pipe penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads, and what we are called in for most is service penetrations left open after M&E works and fire stopping installed outside its tested range. Looking for mastic applicators who cover Three Chimneys? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Barn and farm-building conversions near places like Three Chimneys 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.
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’re clear about what is covered before work starts.

Service penetrations in Three Chimneys buildings
Three Chimneys lies roughly 40 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
For a hospital such as Benenden Hospital (2.3 miles south of Three Chimneys), penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
Three Chimneys is about 11 miles south of Maidstone, in Kent. Anywhere in TN27, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. If others near Three Chimneys need work, visits can be combined. You will have a fixed quote before work starts.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Send your site hours and access windows
- Tell staff and tenants when we’ll be in
- Arrange parking or a loading space
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small. Halls, stores and units around places like Three Chimneys may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Your questions answered
Is Three Chimneys off your patch?
No. Places such as Three Chimneys are covered as much as the big towns. 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 does the BS 476 change mean for fire-rated sealant in Three Chimneys?
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.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Ask the designer to confirm details early on refits
- Don’t let anyone top up a fire seal with the wrong product
- Keep product data and details in the fire safety file
- Report damaged or disturbed seals as soon as they’re spotted
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.
