How we handle fire stopping in Cleghorn

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. If you have hidden openings found during inspections and builders’ foam or ordinary silicone in compartment walls, we can help, whatever the surface. A single leaking joint is often how a building in Cleghorn first comes to us: we look at the rest while we’re there and tell you what we find.

Travel to smaller places like Cleghorn is planned so every penetration is sealed on one trip. Send the specification and photographs of the openings, with sizes if you have them.

A 12-month guarantee applies to all our work in South Lanarkshire. Should something we installed fail, call the office on 01277 525 020 or email the details over and we’ll come back to it.

Compartments and services around Cleghorn

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to 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.

In a school such as Lanark Grammar School, fire-rated sealant goes in around service penetrations where it is specified. Shop fits on retail sites such as Braidfute Retail Park, 1.7 miles south-west of Cleghorn, can bring new services through fire-resisting walls between units, to be sealed with the specified product.

Cleghorn is about 5 miles south-east of Carluke, in South Lanarkshire. Any commercial site in Cleghorn is covered, for single jobs and planned programmes alike. Across South Lanarkshire, 134 places are covered, Cleghorn among them. For work in that direction, see our Glasgow page.

If you need fire stopping in ML11, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

Site staff or a sealant specialist?

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.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Common questions from Cleghorn clients

Is Cleghorn too far out for you?

No. Places such as Cleghorn are covered as much as the big towns. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

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

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.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months on every job.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Common problems we fix in Cleghorn

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

Most enquiries start with one or more of the following:

  • Fire sealant pulled out of the opening
  • Improvised or mixed-product fire seals
  • Fire seals cut back for extra cables and never reinstated
  • Non-fire-rated filler around services

For a hospital such as Lockhart Hospital, which lies south-west of Cleghorn, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

What to look for in a quote

  • How long is the guarantee, and what does it include?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will RAMS and insurance details be available?
  • Whether old or failed sealant will be cut out, not overlaid

Questions to ask before you appoint anyone

What happens if it’s left?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Cleghorn before they leak.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Cleghorn, we aim for one trip, so photos, sizes and a full list matter. External joints need a dry spell as well.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows
  • Make sure the joints can be reached

What the job involves on each surface

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
