Fire stopping in Hillend

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Fire stopping in Hillend, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. If you have expanding foam used as fire stopping and old intumescent sealant that has split away, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hillend, preparation and product choice get the time they need.

Around smaller places such as Hillend, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Compartment walls and floors in Hillend

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, using products tested for the way they’re used. We install what’s specified, to the product’s tested detail.

Campus buildings at universities such as University of Edinburgh - Easter Bush Campus, 1.5 miles south of Hillend, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Holiday works at schools like Gracemount High School often leave service openings to seal before pupils return.

Hillend is about 2 miles south-west of Southhouse, in Midlothian. Anywhere in EH10, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Midlothian, 34 places are covered, Hillend among them.

Work on service penetrations is covered throughout EH10, whatever the building. For a building on Pentland Road and Seafield Moor Road or nearby, we can quote for service penetrations. Nearby places we also cover include Old Pentland (1 mile east), Bilston (1 mile south-east), Loanhead (2 miles east), Burdiehouse (2 miles north-east) and Roslin (2 miles south-east). Further afield, our area takes in Bonnyrigg (4 miles east), Dalkeith (5 miles east), Penicuik (4 miles south), Gorebridge (6 miles south-east), Newtongrange (5 miles east) and Mayfield (6 miles east).

Landmarks near Hillend

The nearest railway station is Slateford station, roughly 3.3 miles north-west.

The countryside around Hillend includes Duddingston Loch and Caerketton Hill.

What happens if it’s left?

Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Hillend, a repair visit takes planning, so it’s better to act early.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

What we’re called out for in Hillend

Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access normally bring them to light.

Most enquiries start with something like this:

  • Unsealed joints where partitions meet the slab
  • Hidden openings found during inspections
  • Penetration schedules that need working through
  • Old intumescent sealant that has split away

In a building such as Fairmilehead Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Our contractor checklist

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Where we can, we combine work around Hillend with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Flag any permit to work we will need
  • Agree which areas must stay open
  • Point out parking and an unloading spot

FAQs: Hillend

Can you work around term dates at a campus such as University of Edinburgh - Easter Bush Campus?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Would you work within a site like Ellen's Glen Community Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Can the sealant be colour-matched?

That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

What do BS EN 1366-3 and BS EN 13501-2 mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. That rating only holds when the product is installed to its tested detail.

What do you charge?

We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.

Do you take on multi-site work?

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

Aftercare for building managers

Problems stay small when the joints are checked regularly. In particular:

  • Flag new cables with no seal around them
  • Keep general-purpose fillers away from compartment walls
  • Arrange inspection before areas are covered up
  • Ask which product is in place before decorating

During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged.

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, not months later.
