How we handle fire stopping in Crossmichael

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. The enquiries we see most involve unsealed penetrations discovered above suspended ceilings and fire-rated sealant that has cracked or shrunk back, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and linear gaps at wall heads. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Crossmichael, preparation and product choice get the time they need.

Hotels and care homes around smaller places like Crossmichael often have services added during refurbishment. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email us and we will come back to it.

Compartments and services around Crossmichael

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, with proprietary products, intumescent ones included, tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

Hotels like Culgruff House Hotel (under half a mile east of Crossmichael) are refurbished in phases, and each phase can open up compartment walls. Industrial units on estates such as Abercromby Industrial Park, 2.5 miles south-east of Crossmichael, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Crossmichael is about 16 miles south-west of Dumfries, in Dumfries and Galloway. We send applicators to Crossmichael for service penetrations, handled exactly as we handle every other area. We work across 139 places in Dumfries and Galloway, from busy centres to rural villages. We also cover Glasgow, around 62 miles from Crossmichael.

Work on service penetrations is covered throughout DG7, whatever the building. For a building on Main Street, St Michael's Road and St Michael's Crescent or nearby, send details and we will quote for service penetrations. Nearby places we also cover include Glenlochar (1 mile south), Castle Douglas (3 miles south-east), Kirkpatrick Durham (4 miles north-east), Bridge of Dee (4 miles south) and Kelton Hill (4 miles south) for service penetrations. Nearby towns on our patch include Kirkcudbright (10 miles south), Dalbeattie (7 miles south-east) and Gatehouse of Fleet (10 miles south-west).

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Jobs near Crossmichael are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
  • Send your site hours and access windows

Advice

Should maintenance staff do it?

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Different surfaces, different methods

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.

How the quote is worked out

We price every job individually. The main factors are:

  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits
  • Specialist products, such as fire-rated or hygienic sealants
  • Access and working height

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What to include in your enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Access details, including height
  • What the building is and how it’s used
  • The product your specification calls for
  • A wide shot and a close-up of the area

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Walls or floors that aren’t fire-resisting to begin with
  • Large openings beyond what any sealant detail covers
  • Fire risk assessments, a job for a competent assessor

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

FAQs: Crossmichael

Is Crossmichael too small for you to travel to?

No. Places such as Crossmichael are covered as much as the big towns. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

How do the Scottish rules apply to fire-rated sealing in Crossmichael?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months on every job.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Common problems we fix in Crossmichael

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.

Things that typically lead to an enquiry:

  • Openings found when ceilings come down for a refit
  • Fire seals cut back for extra cables and never reinstated
  • Penetration schedules that need working through
  • Unsealed joints where partitions meet the slab

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