Fire stopping in Wigtown

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Site teams most often ask us about unsealed joints where partitions meet the slab and damaged fire seals in risers and voids, on cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations. Whoever orders the work in Wigtown, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In smaller Scottish places like Wigtown, 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.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Building owners, agents and FMs in Wigtown

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

What we can’t put right

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Construction that lacks the fire resistance the seal relies on
  • Issuing fire ratings or certificates for seals

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Leave it or put it right?

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Wigtown, a repair visit takes planning, so it’s better to act early.

A quote for service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

Service penetrations in Wigtown buildings

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, and products should be tested for their end use. We install fire-rated sealant to that tested detail where it is specified.

Halls and meeting rooms at places like Sacred Heart Church sometimes gain new services, and any compartment wall crossed needs the specified seal. Buildings near Wigtown get the fire-rated product that’s specified, installed to its tested detail.

Wigtown is about 24 miles east of Stranraer, in Dumfries and Galloway.

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. For a building near Wigtown, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  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. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Agree which areas must stay open
  • Let building users know which areas are affected
  • Share your working hours and any access restrictions

Advice

Common questions from Wigtown clients

Do you decide the fire-stopping details for buildings in Wigtown?

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.

What do Scotland’s building standards say about service penetrations in Wigtown?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. Design sits with the designer and the verifier; installation to the tested detail is our part.

How many days will you need on site?

It depends on the scope, but the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Aftercare for building managers

To get the most from the new sealant:

  • Get seals inspected before ceilings and boxing close
  • Flag new cables with no seal around them
  • Settle who seals which penetrations at the start of a project
  • Ask which product is in place before decorating

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way unless the designer specifies otherwise.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

How the job changes by surface

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
