Fire stopping for businesses in Thomshill

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle fire stopping in Thomshill

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. Most enquiries involve expanding foam used as fire stopping and openings left by services added after handover, on small duct penetrations where the tested detail allows, cable penetrations and joints between fire-resisting walls and floors. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Thomshill is the same: the right product in a properly prepared joint.

Around smaller places such as Thomshill, 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.

Our workmanship is guaranteed for 12 months, in Thomshill as everywhere else we work. If our installation lets you down in that time, we return and fix it.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. For work around Thomshill, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. The specification and schedule come first, so we know which details apply.
  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.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Preparing the site

  • Make sure the joints can be reached
  • Confirm the product named in the specification
  • Agree which areas must stay open

Advice

Common problems we fix in Thomshill

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.

Common reasons buildings call us in:

  • Expanding foam used as fire stopping
  • Fire stopping installed outside its tested range
  • Service penetrations left open after M&E works
  • Fire sealant pulled out of the opening

On estates like Troves Industrial Estate, which lies north-east of Thomshill, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Questions about Thomshill

Is a smaller place like Thomshill outside your area?

Not at all. Thomshill is within our area. Every Scottish council area is within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you take on work at healthcare sites like Dr Gray's Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

How many days will you need on site?

That varies with the scale of the job, but the work normally 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.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Can you reseal penetrations after our M&E works?

Yes. Share the penetration schedule and product details and a fixed quote follows. We can follow the services contractor floor by floor so areas aren’t left open.

What the job involves on each surface

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter, so we check before sealing.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance along with any permits your site needs.

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 typically a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Thomshill before they leak.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Where services cross fire walls in Thomshill

Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, and products should be tested for their end use. We install what’s specified, to the product’s tested detail.

For a building such as Birnie Kirk, new heating or data runs are the usual reason penetrations need sealing. Schools such as Elgin High School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Thomshill is about 3 miles south of Elgin, in Moray. Across the IV30 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Thomshill is one of 59 places in Moray on our list. For work in that direction, see our Aberdeen page, about 54 miles away.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
