Fire stopping across Leith

Fire stopping in Leith, done properly

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations, and what we are called in for most is fire stopping installed outside its tested range and fire sealant pulled out of the opening. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Leith is the same: the right product in a properly prepared joint.

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 Leith, specified fire-rated sealant is installed as the maker’s tested detail describes.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Commercial clients in Leith

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Leith. One quote can cover more than one site, so there’s one set of paperwork to deal with.

How the job changes by surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.

Masonry and concrete

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

Leith: questions and answers

Do you work in occupied care homes around Leith?

Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.

Is hospital work, at somewhere like Western General Hospital (Edinburgh), something you do?

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.

Are you members of a third-party fire-stopping installer scheme?

No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t. Where it isn’t required, we install the specified sealant to the maker’s details.

What site paperwork can you supply?

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.

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. The rating applies to the product as tested.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

What will the job cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Ask the designer to confirm details early on refits
  • Treat an open penetration as a priority repair
  • Check risers and ceiling voids after each round of works
  • Record which product was used where

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.

Fire stopping in Leith: the local picture

Leith has five care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. We install fire-rated sealant to the tested detail where it is specified. The area within 2 miles of Leith holds a good number of hotels. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.

For a unit at a site such as Tower Street Industrial Estate, less than half a mile to the south-east of Leith, new power or data runs between office and warehouse can breach a compartment wall. Colleges such as Royal College of General Practitioners Edinburgh, 2.1 miles south-west of Leith, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. On a hospital site such as Western General Hospital (Edinburgh), 2.8 miles to the south-west of Leith, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Leith is about 3 miles north-east of Edinburgh, in Edinburgh. Commercial clients in Leith can call on us for service penetrations, as part of our coverage of Edinburgh. We work across 174 places in Edinburgh.

Business premises anywhere in EH6, EH5 and EH1 are within our area. For a building on Fyfe Lane, Haig Lane and Mill Lane or nearby, we can quote for service penetrations. Sites close to Leith are covered too, including Timber Bush (1 mile south), North Leith (1 mile south-west), Bonnington (1 mile south-west), Newhaven (1 mile west) and Victoria Park (1 mile west). Further afield, our area takes in Edinburgh (3 miles south-west), West End (3 miles south-west), West Coates (3 miles south-west), Sciennes (3 miles south), Merchiston (3 miles south-west) and Newington (3 miles south). As one of the bigger centres in Edinburgh, Leith has a broad mix of commercial, public and industrial buildings, and we cover them all.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Reviewing a building’s overall fire safety
  • Signing off or certifying a building’s fire stopping
  • Openings that need collars, wraps, batts or boards rather than sealant

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

What we seal

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

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Work on a big city site in Scotland usually involves inductions and permits. Tell us the rules and we’ll work to them.

  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. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Preparing the site

  • Confirm the product named in the specification
  • Send your site hours and access windows
  • Arrange parking or a loading space
