About our fire stopping in Bridgend

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 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. So our job is to reproduce that arrangement faithfully. Most enquiries involve openings found when ceilings come down for a refit and seals disturbed by maintenance and left open, across service gaps in risers, joints between fire-resisting walls and floors and linear gaps at wall heads. A specialist sealant contractor works differently from a general builder: in Bridgend, that means joint design, primers and backing rod as standard.

In smaller Scottish places like Bridgend, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Those penetrations are closed with the product the specification names, built up as tested.

A 12-month guarantee applies to all our work in West Lothian. If an installation problem shows up, phone 01277 525 020 or email us and we’ll arrange a return visit.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Where we can, we combine work around Bridgend with other jobs nearby. Tell us how flexible your dates are.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Share your working hours and any access restrictions

Questions about Bridgend

Is Bridgend too far out for you?

No. Small places get the same service as large ones. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

Do you take on work at healthcare sites like St Michael's Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Can you fire stop behind the services contractors?

Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see, and we reseal them to the specified detail.

Can you quote from photographs?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Are you members of a third-party fire-stopping installer scheme?

No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. If your contract requires third-party installer certification, we’re not the right fit for that package.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

How many days will you need on site?

That varies with the scale of the job, though a typical visit usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we’ll set out a timescale with the quote.

When to bring in a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Issuing fire ratings or certificates for seals
  • Plastic pipes whose detail calls for a collar or wrap
  • Fire risk assessments, a job for a competent assessor

If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think before you book.

Surfaces we seal

  • Small duct penetrations where the tested detail allows
  • Cable penetrations
  • Joints between fire-resisting walls and floors
  • Pipe penetrations
  • Linear gaps at wall heads
  • Service gaps in risers

After the work

A few simple habits keep the new joints working:

  • Keep general-purpose fillers away from compartment walls
  • Have penetrations checked while they can still be seen
  • Include service cupboards in routine inspections
  • Put resealing into every M&E and fit-out package

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Surface by surface

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.

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail.

Where services cross fire walls in Bridgend

In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, using products tested for the way they’re used. We install fire-rated sealant to that tested detail where it is specified.

Holiday works at schools like Winchburgh Academy often leave service openings to seal before pupils return. Wherever services are added at a hospital such as St Michael's Hospital, 2.1 miles west of Bridgend, the compartment line has to be made good with the specified product. For a unit at a site such as Greendykes Industrial Estate, 2.9 miles to the south-east of Bridgend, new power or data runs between office and warehouse can breach a compartment wall.
