Fire stopping in Port Glasgow, done properly

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. If you have hidden openings found during inspections and open linear gaps along the top of fire-resisting walls, we can put it right, whatever the surface. A single leaking joint is often how a building in Port Glasgow first comes to us: we look at the rest while we’re there and tell you what we find.

When contractors add cables and pipes in a Scottish town building, gaps through fire-resisting walls are often left behind. If fire-rated sealant is the named product, it is installed as tested; if the detail needs a different item, we’ll point that out.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Do you need fire stopping in Port Glasgow?

Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access typically bring them to light.

If one of these sounds familiar, it’s time for a closer look:

  • Openings left by services added after handover
  • Damaged fire seals in risers and voids
  • Fire-rated sealant that has cracked or shrunk back
  • Head-of-wall gaps with no fire seal

Older community buildings such as Clune Park Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Questions to ask before you book

  • What level of public liability insurance do they hold?
  • How they handle RAMS and site documents
  • How they’ll work around occupants
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire risk assessments, a job for a competent assessor
  • Plastic pipes whose detail calls for a collar or wrap

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What we seal

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

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • Location, for remote and island sites
  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • Specialist products, such as fire-rated or hygienic sealants

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Where the site is, with the postcode
  • Specification clauses that apply
  • Rough lengths or quantities, or drawings if you have them
  • Anything awkward about access or site hours

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, ring 01277 525 020 or email us.

Surface by surface

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables, so we check before sealing.

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. We follow whatever the detail requires and flag anything we can’t match.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself usually taking anything from one day to a planned run of visits, depending on the number of seals and the access. Industrial estates and retail parks around towns like Port Glasgow typically have yard space and site rules. Central premises can need a little more planning for parking.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Have the specification and drawings to hand
  • Let us know about inductions and permits
  • Share the asbestos register for older buildings

Ask for a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

Compartments and services around Port Glasgow

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, with proprietary products, intumescent ones included, tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail.

Where a unit on an estate such as Port Glasgow Industrial Estate, less than half a mile to the south of Port Glasgow, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. On a hospital site such as Broadfield Hospital, 1.3 miles to the east of Port Glasgow, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Port Glasgow is about 12 miles north-west of Paisley, in Inverclyde. Businesses, contractors and managing agents in Port Glasgow use us for work on service penetrations. Across Inverclyde, 19 places are covered, including Port Glasgow. Glasgow is covered too, around 16 miles from Port Glasgow.

Business premises anywhere in PA14 and PA15 are within our area for service penetrations. Streets here include Stanton Square, Ardmore Road and Montgomerie Street.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Questions about Port Glasgow

Can you work at a site such as Port Glasgow Industrial Estate, by Port Glasgow?

Yes. We cover Port Glasgow and the area around it, including industrial estates, business parks and retail parks such as Port Glasgow Industrial Estate. Photos and a short description are enough for a first look.

Which Scottish guidance covers penetration seals in Port Glasgow?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

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 external work may be moved if conditions aren’t right. Internal work is far less affected.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

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, since fresh sealant will not bond reliably to aged material.
