After the work
Once the work is signed off, these steps help:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Ask which product is in place before decorating
- Ask the designer to confirm details early on refits
- Look above ceilings when tiles are lifted for other jobs
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
Fire stopping in Knox Bridge, done properly
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. The enquiries we see most involve penetration schedules that need working through and openings found when ceilings come down for a refit, across joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads. Searching for sealant specialists in Knox Bridge? We have been sealing commercial buildings since 2005.
Barn and farm-building conversions near places like Knox Bridge often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Issuing fire ratings or certificates for seals
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Openings that need collars, wraps, batts or boards rather than sealant
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
Surfaces we seal
- Pipe penetrations
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Jobs in and around smaller places like Knox Bridge are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- 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
- Point out parking and an unloading spot
- Agree which areas must stay open
- Tell us your opening times and when work is allowed
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Related advice
Do you need fire stopping in Knox Bridge?
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.
Clients typically get in touch after noticing one or more of the following:
- Fire-stopping items raised at inspection or handover
- Fire-rated sealant that has cracked or shrunk back
- Unsealed penetrations discovered above suspended ceilings
- Fire stopping installed outside its tested range
For a hotel such as The King's Head Hotel, which lies north of Knox Bridge, penetration seals are worth checking after any refit or services upgrade.

Questions we are asked in Knox Bridge
What happens to BS 476 references for fire stopping in Knox Bridge?
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is a smaller place like Knox Bridge outside your area?
No. Places such as Knox Bridge are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
Is colour matching possible?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
What will the job cost?
Each job is quoted on its own details. To get one, phone 01277 525 020 or send photos by email with a description of the work.

Service penetrations in Knox Bridge buildings
In England, Approved Document B covers fire stopping of openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. Knox Bridge is about 38 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.
Large healthcare estates like Benenden Hospital, 4.4 miles south-east of Knox Bridge, change their services often, so penetration seals are worth checking after M&E work.
