Fire stopping in Dunbeg, done properly

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. If you’re dealing with penetration schedules that need working through and damaged fire seals in risers and voids, we can put it right, whatever the surface. Whoever orders the work in Dunbeg, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In smaller Scottish places like Dunbeg, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What sets the cost

To price the job, we consider:

  • Quantities, in metres or numbers
  • Any access equipment needed
  • The site’s rules and procedures
  • Removal of failed or old sealant

Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • Rough lengths or quantities, or drawings if you have them
  • Your programme or deadline
  • Asbestos survey details if the building is older
  • The product your specification calls for

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Aftercare for building managers

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

  • Don’t let anyone top up a fire seal with the wrong product
  • Get seals inspected before ceilings and boxing close
  • Check risers and ceiling voids after each round of works
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original unless the designer specifies otherwise.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Dunbeg, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Have the specification and drawings to hand
  • Tell staff and tenants when we will be in
  • Tell us which areas need to stay in use

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Signing off or certifying a building’s fire stopping
  • Plastic pipes whose detail calls for a collar or wrap
  • Writing the fire-stopping specification

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly.

Joints and surfaces we work on

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

Dunbeg: questions and answers

Is Dunbeg too small for you to travel to?

No. Small places get the same service as large ones. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

Which Scottish guidance covers penetration seals in Dunbeg?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Is colour matching possible?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Common problems we fix in Dunbeg

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.

Clients usually get in touch after noticing one or more of the following:

  • Hidden openings found during inspections
  • Fire-rated sealant that has cracked or shrunk back
  • Seals disturbed by maintenance and left open
  • Head-of-wall gaps with no fire seal

Halls and meeting rooms at places like Dunstaffnage Chapel sometimes gain new services, and any compartment wall crossed needs the specified seal.

What your quote should include

  • Who will actually carry out the work
  • What the guarantee covers, and for how long
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Proof of insurance
