Fire stopping for Greendykes sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

FAQs: Greendykes

Can you work on a hospital site such as Royal Infirmary of Edinburgh (Little France)?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Can you work in a care home near Greendykes with residents in?

Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.

Will you just go over the old sealant?

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

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Can you send site paperwork?

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.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Fire stopping in Greendykes

It helps to set out our role at the start. 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 on buildings around Greendykes. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and pipe penetrations, and what we are called in for most is fire-stopping items raised at inspection or handover and fire seals cut back for extra cables and never reinstated. Whether you call it commercial sealant work, mastic application or joint sealing, in Greendykes it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Under Scotland’s building standards, a service penetration should keep at least the fire resistance duration of the wall or floor it passes through. For a building in Greendykes, specified fire-rated sealant is installed as the maker’s tested detail describes.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

After the work

Keep the joints in good shape with a few simple steps:

  • Foam or ordinary sealant is never a fire-seal repair
  • Check with the data sheet before painting over fire sealant
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Include service cupboards in routine inspections

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. 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

Metal pipes

Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening.

Do you need fire stopping in Greendykes?

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Things that normally lead to an enquiry:

  • Openings found when ceilings come down for a refit
  • Seals disturbed by maintenance and left open
  • Old intumescent sealant that has split away
  • Builders’ foam or ordinary silicone in compartment walls

Refits at places like Craigmillar Shopping Centre (to the north-west of Greendykes) often reroute services through walls between units.

Choosing a commercial sealant contractor

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Where services cross fire walls in Greendykes

There are plenty of hotels within about 2 miles of Greendykes. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. The 2 miles around Greendykes include six care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.

For a hospital such as Royal Infirmary of Edinburgh (Little France), 0.6 miles to the south-west of Greendykes, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. For a building such as Robin Chapel, new heating or data runs are the usual reason penetrations need sealing.

Greendykes is about 3 miles east of Edinburgh, in Edinburgh. Anywhere in EH16, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Greendykes is one of 174 places we cover in Edinburgh.

Commercial sites across EH16, EH15 and EH22 are covered. If your site is on Hay Avenue, Aspen Road and Friary Road or close by, send details and we will quote for service penetrations. With the A6095 nearby, Greendykes is straightforward for us to reach. Close to Greendykes, our area also takes in The Wisp (1 mile south-east), Niddrie Mains (1 mile north-east), Niddrie (1 mile east), Craigmillar (1 mile west) and Bingham (1 mile north).

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. For premises in Greendykes, tell us about access times, shared entrances and any building rules, so the work can be phased and areas kept in use.

  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 so the seal starts clean.
  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.

What we need from you

  • Tell us what induction or permit system the site runs
  • Warn occupants and staff about the work
  • Explain the parking and delivery arrangements

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Signing off or certifying a building’s fire stopping
  • Fire risk assessments, a job for a competent assessor
  • Large openings beyond what any sealant detail covers

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

Joints and surfaces we work on

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