Fire stopping in Cadder

Fire stopping for commercial buildings in Cadder

Facilities managers in Cadder often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on small duct penetrations where the tested detail allows, service gaps in risers and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are seals disturbed by maintenance and left open and fire-stopping items raised at inspection or handover. Facilities teams, main contractors and managing agents in Cadder tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Refurbishments in small hotels, schools and care homes around places like Cadder can leave gaps around new services. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Surface by surface

Drylining partitions

Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Travel to smaller Scottish places like Cadder is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  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.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Confirm the product named in the specification
  • Flag any permit to work we’ll need

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Why it’s worth doing now in Cadder

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Cadder before they leak.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

Why appoint us

  • Our applicators hold CSCS cards
  • One phone line for London, the South East and Scotland
  • Joints cleaned back to sound surfaces
  • Work to your specification and the manufacturer’s guidance

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Reviewing a building’s overall fire safety
  • Gaps in walls that were never built as compartment walls
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Where we work in Cadder

  • Pipe penetrations
  • Small duct penetrations where the tested detail allows

  • Service gaps in risers
  • Linear gaps at wall heads
  • Cable penetrations

Fire-rated sealing for Cadder buildings

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 proprietary products, intumescent ones included, tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

For a site team at a college like New College Lanarkshire - Kirkintilloch Campus, which lies north-east of Cadder, fire-rated sealing is best scheduled after the summer works. For an estates team at a campus like University of Strathclyde, which lies south of Cadder, summer M&E works are normally followed by a round of penetration sealing.

Common problems we fix in Cadder

Some service penetrations were never sealed at all. Inspections, refurbishments and ceiling access typically bring them to light.

Look out for the following:

  • Improvised or mixed-product fire seals
  • Openings found when ceilings come down for a refit
  • Non-fire-rated filler around services
  • Snag lists that include open service penetrations

For a unit at a site such as Low Moss Industrial Estate, under half a mile east of Cadder, new power or data runs between office and warehouse can breach a compartment wall.

Choosing a commercial sealant contractor

Your questions answered

How do the Scottish rules apply to fire-rated sealing in Cadder?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Can you work at a site such as Low Moss Industrial Estate, by Cadder?

Yes. Estates, retail parks and business parks around Cadder, Low Moss Industrial Estate among them, are all within reach. To start, just speak to us on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What about RAMS and site documents?

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.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.
