Fire stopping for commercial buildings in Dillarburn

Facilities managers in Dillarburn often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. Most enquiries involve fire stopping installed outside its tested range and unsealed penetrations discovered above suspended ceilings, across pipe penetrations, service gaps in risers and small duct penetrations where the tested detail allows. Looking for mastic applicators who cover Dillarburn? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

In smaller Scottish places like Dillarburn, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

On site: what to expect

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 a building near Dillarburn, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  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.

Before we start on site

  • Share the asbestos register for older buildings
  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use

Questions about Dillarburn

Can you work on a hospital site such as Birkwood Castle?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as Gateside Industrial Estate, by Dillarburn?

Yes. Estates, retail parks and business parks around Dillarburn, Gateside Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Do you cover Dillarburn?

Yes. We take on work across Dillarburn, and the same phone number covers every area.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

How long does a job like this take?

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

Compartments and services around Dillarburn

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, with products tested for that end use. We install what’s specified, to the product’s tested detail.

On a hospital site such as Birkwood Castle (1.6 miles south-west of Dillarburn), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Where a unit on an estate such as Gateside Industrial Estate, which lies south of Dillarburn, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Dillarburn is about 6 miles south of Carluke, in South Lanarkshire. Our applicators travel to Dillarburn for work on service penetrations. We work across 134 places in South Lanarkshire. Our Glasgow page has more on work in that area.

What we are called out for in Dillarburn

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

These are often picked up first by site or facilities staff:

  • Fire stopping installed outside its tested range
  • Openings left by services added after handover
  • Seals disturbed by maintenance and left open
  • Unsealed penetrations discovered above suspended ceilings

For a school such as Lesmahagow High School, penetration sealing fits best at the end of the summer works.

What to look for in a quote

  • Do they follow the manufacturer’s priming guidance?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • The terms of the workmanship guarantee
  • How the existing material will be dealt with

Questions to ask before you appoint anyone

After the work

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Foam or ordinary sealant is never a fire-seal repair
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Get seals inspected before ceilings and boxing close
  • Check risers and ceiling voids after each round of works

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there instead of being left for someone else.

How the job changes by surface

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We confirm material and size first and tell you if sealant isn’t the right product.

Owners, agents and contractors

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

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Fire risk assessments, a job for a competent assessor
  • Large openings beyond what any sealant detail covers
  • Construction that lacks the fire resistance the seal relies on

If in doubt, ring 01277 525 020 or send photos by email and we will say what we think before you book.

Joints and surfaces we work on

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