Fire stopping in Westergate
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations, and the failures we’re asked to look at most are fire-rated sealant that has cracked or shrunk back and open linear gaps along the top of fire-resisting walls. Facilities teams, main contractors and managing agents in Westergate tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Westergate, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Your questions answered
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Westergate?
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.
Can you seal penetrations in a hotel in Westergate after a refit?
Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.
Fire stopping in Westergate: the local picture
The 2 miles around Westergate include five care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Schools such as Aldingbourne Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. At a university such as University of Chichester, which lies south-west of Westergate, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Westergate is about 3 miles north of Bognor Regis, in West Sussex.

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. If neighbouring businesses or buildings around Westergate need work too, visits can be combined. Tell us your site hours and we will plan around them.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- 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.
Before we start on site
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000
- Confirm the product named in the specification

Advice
Quoting for work in Westergate
Each job is priced on its own details. The things that drive the figure:
- Site requirements such as inductions and permits
- Phasing around occupants
- Access and working height
- Quantities, in metres or numbers
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
- The asbestos register, for older buildings
- Access details, including height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
What we’re called out for in Westergate
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.
If one of these sounds familiar, it’s time for a closer look:
- Fire stopping installed outside its tested range
- Unsealed openings around new pipes and cables
- Snag lists that include open service penetrations
- Damaged fire seals in risers and voids
On a site such as The Woodhorn Business Centre (1.6 miles west of Westergate), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
Comparing quotes
- What site paperwork they can supply
- Will failed sealant be removed rather than covered?
- Are they CHAS accredited or on Constructionline?
- Will CSCS-carded applicators be on site?
Why deal with it now?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Different surfaces, different methods
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.

When to bring in a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
