Fire stopping for Blackhall sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping in Blackhall

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on service gaps in risers, linear gaps at wall heads and pipe penetrations, and the failures we’re asked to look at most are snag lists that include open service penetrations and improvised or mixed-product fire seals. Facilities teams, main contractors and managing agents in Blackhall tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Scotland’s non-domestic Technical Handbook says a service penetration ought to match, as a minimum, how long the wall or floor resists fire. In Blackhall, penetrations get the fire-rated sealant the specification asks for, built to its tested arrangement.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Compartments and services around Blackhall

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, using products tested for the way they’re used. Where fire-rated sealant is specified, that’s what we install, to the tested detail. The 2 miles around Blackhall include six care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product.

For a hospital such as Western General Hospital (Edinburgh), 0.8 miles to the east of Blackhall, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. Hotels like Village Hotel (1 mile north-east of Blackhall) are refurbished in phases, and each phase can open up compartment walls. For a site team at a college like Edinburgh College - Granton Campus (1.3 miles north of Blackhall), fire-rated sealing is best scheduled after the summer works.

Blackhall is about 2 miles north-west of Edinburgh, in Edinburgh. Commercial clients in Blackhall use us for work on service penetrations. We work across 174 places in Edinburgh.

When something else is needed

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Fire doors, dampers or other fire safety equipment
  • Gaps in walls that were never built as compartment walls
  • Issuing fire ratings or certificates for seals

If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Why it’s worth doing now in Blackhall

A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail. In a tenement or shared city building, water from a failed joint can reach other owners’ property, which makes early repair simpler for everyone. Fixing it promptly keeps repairs small.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Why appoint us

  • Specification-led, product-correct work
  • One phone line for London, the South East and Scotland
  • Health and safety: CHAS accredited
  • Fully insured, including public liability cover

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Check risers and ceiling voids after each round of works
  • Brief every trade that openings they make must be sealed
  • Don’t let anyone top up a fire seal with the wrong product
  • Report damaged or disturbed seals as soon as they’re spotted

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

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.

FAQs: Blackhall

Would you work within a site like Western General Hospital (Edinburgh)?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What do Scotland’s building standards say about service penetrations in Blackhall?

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. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

What do you charge?

There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Surface by surface

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, along the full length of the run.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.

On site: what to expect

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Work on a big city site in Scotland typically involves inductions and permits. Tell us the rules and we will work to them.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification
  • Move anything stored against the joints
