Fire stopping in Stranraer: the local picture

A good number of hotels sit less than 2 miles from Stranraer. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, with products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

At a college such as Dumfries & Galloway College - Stranraer Campus, under half a mile to the south-east of Stranraer, checking penetration seals after summer M&E works is good practice. In a hotel such as The George Hotel, which lies east of Stranraer, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. On estates like Castle Kennedy Industrial Estate, which lies south-east of Stranraer, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Stranraer is in Dumfries and Galloway. Businesses, contractors and managing agents in Stranraer use us for work on service penetrations, as part of our coverage of Dumfries and Galloway. Stranraer is one of 139 places we cover in Dumfries and Galloway. Glasgow is covered too, some 72 miles away.

Work on service penetrations is covered throughout DG9, whatever the building. Among the streets we cover are High Street, Market Street and Hanover Square, and sites on any of them can send details for a fixed quote. You’ll find Stranraer on or near the A75 and A77, so getting applicators and materials to site is simple.

Fire stopping for commercial buildings in Stranraer

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. Most enquiries involve unsealed penetrations discovered above suspended ceilings and non-fire-rated filler around services, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and cable penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Stranraer is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Fire-rated sealing in Stranraer follows the specification set by the designer: design and sign-off sit with the designer, fire engineer or the local authority verifier, and we install what is specified. Any record-keeping you need is agreed at quote stage.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Stranraer

What shapes the price:

  • The size and state of each joint
  • Distance, for remote addresses
  • The total length or number of joints
  • The site’s rules and procedures

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • What the building is and how it’s used
  • The postcode of the building
  • Clear photos of the problem areas
  • Approximate linear metres or a joint schedule

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email us if you’d rather talk the job through.

When something else is needed

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

  • Fire doors, dampers or other fire safety equipment
  • Plastic pipes whose detail calls for a collar or wrap
  • Walls or floors that aren’t fire-resisting to begin with

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

What we seal

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

What the job involves on each surface

Cables and cable bundles

New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail.

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.

Why it’s worth doing now in Stranraer

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Buildings in towns like Stranraer often have joints of similar age across a whole building or estate. Doing them together saves return visits.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Failed material removed, not covered up
  • Fixed quotes based on photos, drawings or a visit
  • A Constructionline member, so easy to vet
  • Sealing commercial buildings since 2005

On site: what to expect

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. If you manage more than one building in Stranraer, they can be grouped. Give us access times for each.

  1. The specification and schedule come first, so we know which details apply.
  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 first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Send any specification or drawings in advance
  • Flag any permit to work we’ll need
  • Point out any areas we must not close

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Advice

Building owners, agents and FMs in Stranraer

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Questions we are asked in Stranraer

Can you work around term dates at a campus such as Dumfries & Galloway College - Stranraer Campus?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work on a hospital site such as Galloway Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Will fire-rated sealant work on every penetration?

No. Sealant is the right product only where the tested detail says so. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards.
