Fire stopping in Greenfield, done properly
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, often unnoticed. Those on your schedule are closed with the specified product. We work on service gaps in risers, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the usual reasons a site gets in touch are fire-stopping items raised at inspection or handover and head-of-wall gaps with no fire seal. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Greenfield it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Large city estates in Scotland, from universities to hospitals and offices, are re-serviced constantly, and new cabling and pipework through compartment walls is a common reason fire stopping gets breached. Intumescent sealant goes in where the specification calls for it, with backing and depth as tested.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Fire stopping around Greenfield: what changes locally
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, using products tested for the way they’re used. Our part is installing the specified fire-rated sealant to its tested detail.
Residences at universities like University of Strathclyde, 1.7 miles north-west of Greenfield, have compartment walls that must be resealed whenever services change. Colleges such as Glasgow Kelvin College - East End Campus (1.3 miles west of Greenfield) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Greenfield is about 3 miles north of Cambuslang, in Glasgow. Across the G32 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Glasgow, 171 places are covered, Greenfield among them.
Work on service penetrations is covered throughout G32, G33 and G31, whatever the building. If your site is on Glen Road, Glen Avenue and Cardowan Road or close by, we can quote for service penetrations. Access to Greenfield is via the A89. Just outside Greenfield, we also work in Budhill (1 mile south-east), Lightburn (1 mile north), Shettleston (1 mile south), Springboig (1 mile north-east) and Cranhill (1 mile north). A short drive away, we cover Glasgow (4 miles west), Hillhead (5 miles west), Dowanhill (5 miles west), Woodlands (4 miles west), Woodside (4 miles west) and North Kelvinside (5 miles west).
What’s near Greenfield
Around Greenfield, our work takes us to commercial buildings near St Andrew's Secondary School and Parkhead Library. Greenfield has its own railway station: Shettleston station. A little further out are The Forge Shopping Centre (1.2 miles west) and Farme Castle (2 miles south-west). For a walk, there’s Hogganfield Loch and Cathkin Braes.
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Openings that need collars, wraps, batts or boards rather than sealant
- Issuing fire ratings or certificates for seals
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you’re not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer before you book.
What we seal
- Service gaps in risers
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
- Small duct penetrations where the tested detail allows
What happens if it’s left?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. Getting access arranged for a building in Greenfield takes time, so deal with all failing joints while access is up.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
What you get with us
- One phone line for London, the South East and Scotland
- A Constructionline member, so easy to vet
- Specification-led, product-correct work
- Work carried out by CSCS-carded applicators

Do you need fire stopping in Greenfield?
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
It’s worth sending us details if you spot any of the following:
- Openings left by services added after handover
- Improvised or mixed-product fire seals
- Old intumescent sealant that has split away
- Unsealed penetrations discovered above suspended ceilings
Hospital estates such as Lightburn Hospital, under half a mile to the north of Greenfield, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
What to look for in a quote
- What level of public liability insurance do they hold?
- The terms of the workmanship guarantee
- How the existing material will be dealt with
- What site paperwork they can supply
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Keep general-purpose fillers away from compartment walls
- Check with the data sheet before painting over fire sealant
- Arrange inspection before areas are covered up
- File the specified details where the next contractor can find them
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate.
Questions we’re asked in Greenfield
Can you work around term dates at a campus such as University of Strathclyde?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a hospital such as Lightburn Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do the same rules apply to fire stopping in Scotland?
Building standards in Scotland are separate from England’s. Wherever the site is, our work follows the specification and the tested detail.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Will fire-rated sealant work on every penetration?
No. A sealant’s evidence covers set services, gaps and wall or floor types. Outside that, a different product is needed, as set out by the designer.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Work on a big city site in Scotland normally involves inductions and permits. Tell us the rules and we’ll work to them.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Tell us what induction or permit system the site runs
- Send your site hours and access windows

How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Location, for remote and island sites
- Working within restricted access windows
- How much there is to seal
- Any access equipment needed
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
What we need to price the job
However big the job, the same details help:
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
