Fire stopping for Greenhill sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Common problems we fix in Greenhill
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Things that usually lead to an enquiry:
- Openings left by services added after handover
- Openings found when ceilings come down for a refit
- Unsealed joints where partitions meet the slab
- Fire sealant pulled out of the opening
On a site such as Blackford Business Park, which lies south-east of Greenhill, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

About our fire stopping in Greenhill
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Greenhill and nearby. The enquiries we see most involve seals that don’t match their tested detail and old intumescent sealant that has split away, across service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows. A specialist sealant contractor works differently from a general builder: on jobs in Greenhill, preparation and product choice get the time they need.
Tenement blocks and converted stone buildings in Scottish cities often hide old service routes through walls and floors. Wall type and service type decide the product, so both are checked before sealing, and design questions go to the designer or verifier.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

On site: what to expect
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For premises in Greenhill, tell us about access times, shared entrances and any building rules, so the work can be phased and areas kept in use.
- We read the specification, drawings or penetration schedule you send.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints

Surface by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail.
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 usually a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Getting access arranged for a building in Greenhill takes time, so deal with all failing joints while access is up.
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Plastic pipes whose detail calls for a collar or wrap
- Gaps in walls that were never built as compartment walls
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, speak to us on 01277 525 020 or use the quote form and we will say what we think before you book.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Common questions from Greenhill clients
Can work in a care setting near Greenhill go ahead while residents are there?
Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Which Scottish guidance covers penetration seals in Greenhill?
Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.
Do you guarantee your work?
Yes. Workmanship is guaranteed for 12 months on every job.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Other services in Greenhill
Compartments and services around Greenhill
Four care or nursing homes sit less than 2 miles from Greenhill. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, using products tested for the way they’re used. Where fire-rated sealant is specified, that’s what we install, to the tested detail.
For a site team at a college like Royal College of General Practitioners Edinburgh (1.5 miles north of Greenhill), fire-rated sealing is best scheduled after the summer works. Hospital estates such as Astley Ainslie Hospital, 0.5 miles to the south-east of Greenhill, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
