Fire stopping in Innellan

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on service gaps in risers, linear gaps at wall heads and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are fire seals cut back for extra cables and never reinstated and old intumescent sealant that has split away. A specialist sealant contractor works differently from a general builder: in Innellan, that means joint design, primers and backing rod as standard.

Around smaller places such as Innellan, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Where services cross fire walls in Innellan

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 products tested for that end use. Our part is installing the specified fire-rated sealant to its tested detail.

Large healthcare estates like Cowal Community Hospital (5 miles north of Innellan) change their services often, so penetration seals are worth checking after M&E work.

Innellan is about 8 miles south-west of Greenock, in Argyll and Bute. Any commercial site in Innellan is covered, for single jobs and planned programmes alike. Innellan is one of 124 places in Argyll and Bute on our list. Sites around Glasgow have their own page, roughly 27 miles from Innellan.

We take on service penetrations across the PA23 postcode area, for business premises of every kind. Among the streets we cover are Newton Road, Shore Road and Wyndham Road. If your building is just outside Innellan, we cover Toward (1 mile south-west), Wemyss Bay (3 miles east), Bullwood (3 miles north), Skelmorlie (3 miles south-east) and Inverkip (4 miles east).

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For work around Innellan, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Send your site hours and access windows
  • Confirm the product named in the specification
  • Let building users know which areas are affected

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • Walls or floors that aren’t fire-resisting to begin with
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Plastic pipes whose detail calls for a collar or wrap

If you’re not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer.

Surfaces we seal

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

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Check risers and ceiling voids after each round of works
  • Keep general-purpose fillers away from compartment walls
  • File the specified details where the next contractor can find them
  • Treat an open penetration as a priority repair

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Different surfaces, different methods

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.

Metal pipes

Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

Why deal with it now?

Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Innellan before they leak.

When to call us in Innellan

Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

Typical triggers for a call:

  • Open linear gaps along the top of fire-resisting walls
  • Seals disturbed by maintenance and left open
  • Seals that don’t match their tested detail
  • Unsealed penetrations discovered above suspended ceilings

Buildings near Innellan get the fire-rated product that’s specified, installed to its tested detail.

How to choose a sealant contractor

Questions we’re asked in Innellan

What do Scotland’s building standards say about service penetrations in Innellan?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using 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.

Is a smaller place like Innellan outside your area?

Not at all. Innellan is within our area. 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.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Can the building stay open while you work?

Normally, yes. Phased work can be planned so areas stay in use.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you offer coloured sealant?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
