About our fire stopping in Innermessan

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have openings found when ceilings come down for a refit and fire-rated sealant that has cracked or shrunk back, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Innermessan it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Hotels and care homes around smaller places like Innermessan often have services added during refurbishment. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Backing rod, priming and other preparation
  • How much existing material needs removing
  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • Any specification or named product
  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule
  • The type of building and who uses it

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or send details through our quote form.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

On site: what to expect

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Innermessan, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. First we go through the drawings, schedule or specification for the seals 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.

Before we start on site

  • Share the asbestos register for older buildings
  • Make sure the joints can be reached
  • Arrange parking or a loading space

Where services cross fire walls in Innermessan

In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, with proprietary products, intumescent ones included, tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail. A number of hotels sit less than 2 miles from Innermessan. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

At a college such as Dumfries & Galloway College - Stranraer Campus (2.1 miles south-west of Innermessan), checking penetration seals after summer M&E works is good practice. Industrial units on estates such as Castle Kennedy Industrial Estate (2.4 miles south-west of Innermessan) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Innermessan is about 2 miles north-east of Stranraer, in Dumfries and Galloway. We send applicators to Innermessan for service penetrations. Across Dumfries and Galloway, 139 places are covered, including Innermessan. Glasgow is covered too, around 70 miles from Innermessan.

We take on service penetrations across the DG9 postcode area, for business premises of every kind. Sites close to Innermessan are covered too, including Aird (2 miles south-east), Lime Kiln (2 miles south), Stranraer (2 miles south-west), Castle Kennedy (2 miles south-east) and Cairnryan (3 miles north).

Local landmarks in Innermessan

The nearest railway station is Stranraer station, about 1.7 miles south-west. Nearby you will also find Galloway Community Hospital (2.1 miles south-west) and Stranraer Museum (2 miles south-west). For a walk, there’s White Loch.

Questions about Innermessan

Can you work at a site such as Castle Kennedy Industrial Estate, by Innermessan?

Yes. Our area takes in Innermessan and its surroundings, with estates and business parks such as Castle Kennedy Industrial Estate included. A few photographs and the unit address let us price the work.

Do you seal service penetrations in hotels around Innermessan?

Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

What will the job cost?

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

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Surface 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, so we check each one.

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, with no gaps along the run.

Maintenance after handover

After handover, a little attention goes a long way:

  • Agree the fire-stopping specification before services go in
  • Check with the data sheet before painting over fire sealant
  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep product data and details in the fire safety file

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, so check the product data first.

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

When to call us in Innermessan

Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access normally bring them to light.

Site and facilities staff are often the first to spot these:

  • Snag lists that include open service penetrations
  • Old intumescent sealant that has split away
  • Unsealed joints where partitions meet the slab
  • Expanding foam used as fire stopping

On a hospital site such as Galloway Community Hospital, 2.1 miles to the south-west of Innermessan, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Questions to ask before you book

  • Their public liability cover
  • Can the work be phased to keep areas open?
  • Whether primer will be used where the manufacturer specifies it
  • What site paperwork they can supply
