How we handle fire stopping in Trinity

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you have unsealed openings around new pipes and cables and snag lists that include open service penetrations, we can put it right, whatever the surface. Whoever orders the work in Trinity, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Older stone and tenement buildings in Scotland’s cities have typically been re-serviced many times. Before sealing, we confirm the wall or floor and the services passing through, so the product matches the detail, and design questions go to the designer or verifier.

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

Fire stopping around Trinity: how the place shapes the job

A 2-mile radius around Trinity takes in plenty of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. Five care or nursing homes sit less than 2 miles from Trinity. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.

For a site team at a college like Royal College of General Practitioners Edinburgh, 1.6 miles to the south of Trinity, fire-rated sealing is best scheduled after the summer works. On a hospital site such as Western General Hospital (Edinburgh) (1.6 miles south-west of Trinity), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Trinity is about 2 miles north of Edinburgh, in Edinburgh. If you’re looking for fire stopping in Trinity, we can help. Trinity is one of 174 places we cover in Edinburgh for service penetrations.

We take on service penetrations across the EH5, EH6 and EH3 postcode area, whatever the building. Among the streets we cover are York Road, Park Road and Clark Road. Being close to the A901 and A903, Trinity is easy to get to with materials and equipment. If your building is just outside Trinity, we cover Goldenacre (1 mile south-west), Warriston (1 mile south), Boswall (1 mile west), Inverleith (1 mile south-west) and Granton (1 mile west). Bigger towns within reach include Sciennes (3 miles south), Merchiston (3 miles south), Newington (3 miles south), Queensferry (8 miles west), Burgh Muir (3 miles south) and South Portobello (4 miles south-east).

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Gaps in walls that were never built as compartment walls
  • Issuing fire ratings or certificates for seals
  • Reviewing a building’s overall fire safety

If you are not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer before you book.

What we seal

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

What happens if it’s left?

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Failed sealant in a shared building in Trinity can affect more than one owner, which makes early repair simpler for everyone. Acting early avoids disputes and bigger repairs.

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

Why us?

  • Old sealant cut out, never sealed over
  • A fixed quote before work starts
  • Public liability insurance in place
  • Commercial sealant work since 2005

Your questions answered

Can work in a care setting near Trinity go ahead while residents are there?

Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.

Can you work at a site such as North Leith Sands Industrial Estate, by Trinity?

Yes. Our area takes in Trinity and its surroundings, with estates and business parks such as North Leith Sands Industrial Estate included. Photos and a short description are enough for a first look.

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months.

Do you work in Scotland as well as England?

Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor.

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How long does a job like this take?

It depends on the scope, though a typical visit typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we will set out a timescale with the quote.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Quoting for work in Trinity

Quotes vary with the job. It mainly depends on:

  • Induction, permit and paperwork requirements
  • Specialist products, such as fire-rated or hygienic sealants
  • Access and working height
  • Removal of failed or old sealant

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Before you send an enquiry

However big the job, the same details help:

  • Asbestos survey details if the building is older
  • Any specification or named product
  • Photos of the joints, close up and from further back
  • The postcode of the building

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Signs you need fire stopping in Trinity

Openings in fire-resisting walls normally appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

Any of the following is a good reason to get the joints checked over:

  • Service penetrations left open after M&E works
  • Fire sealant pulled out of the opening
  • Snag lists that include open service penetrations
  • Unsealed penetrations discovered above suspended ceilings

Shop fits in centres such as Granton Retail Park (to the west of Trinity) can bring new services through fire-resisting walls between units, which then need the specified seal.

What your quote should include

  • Their public liability cover
  • The terms of the workmanship guarantee
  • Which product they’ll use, and why it suits the joint
  • Health and safety accreditation such as CHAS

Our contractor checklist

What the job involves on each surface

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork normally needs a different solution set by the designer.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Work on a big city site in Scotland usually involves inductions and permits. Tell us the rules and we will work to them.

  1. We start with your penetration schedule, drawings or specification.
  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.
  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.

Getting the site ready

  • Confirm the product named in the specification
  • Tell staff and tenants when we will be in
  • Point out parking and an unloading spot
