About our fire stopping in Lochans

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on pipe penetrations, service gaps in risers and cable penetrations, and the failures we are asked to look at most are improvised or mixed-product fire seals and unsealed openings around new pipes and cables. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lochans, that means joint design, primers and backing rod as standard.

Hotels and care homes around smaller places like Lochans 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When to call us in Lochans

Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access usually bring them to light.

If one of these sounds familiar, it’s time for a closer look:

  • Fire seals cut back for extra cables and never reinstated
  • Non-fire-rated filler around services
  • Penetration schedules that need working through
  • Old intumescent sealant that has split away

Workshops and IT rooms at colleges like Dumfries & Galloway College - Stranraer Campus, 2.2 miles north of Lochans, are re-serviced often, leaving penetrations to seal.

Before you book anyone

  • What level of public liability insurance do they hold?
  • Do they follow the manufacturer’s priming guidance?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will RAMS and insurance details be available?

Choosing a commercial sealant contractor

When something else is needed

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Approving the work on behalf of building control
  • Plastic pipes whose detail calls for a collar or wrap
  • Gaps in walls that were never built as compartment walls

If you’re not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer.

Where we work in Lochans

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

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Lochans: questions and answers

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

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Lochans off your patch?

No. Places such as Lochans are covered as much as the big towns. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

When is resealing likely to be due?

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

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure.

Service penetrations in Lochans 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, using products tested for the way they’re used. We install what’s specified, to the product’s tested detail.

Industrial units on estates such as Castle Kennedy Industrial Estate (to the north of Lochans) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Wherever services are added at a hospital such as Galloway Community Hospital (2.1 miles north of Lochans) the compartment line has to be made good with the specified product.

Lochans is about 3 miles south of Stranraer, in Dumfries and Galloway. We send applicators to Lochans for service penetrations, handled exactly as we handle every other area. Across Dumfries and Galloway, 139 places are covered, including Lochans. We also cover Glasgow, around 74 miles from Lochans.

Commercial sites across DG9 are covered for service penetrations. We cover commercial and managed buildings on Main Street, Mount Terrace and Cairn Terrace and the roads nearby. Nearby places we also cover include Lime Kiln (2 miles north-east), Stranraer (3 miles north), Aird (3 miles north-east), Stoneykirk (3 miles south-east) and Castle Kennedy (3 miles north-east).

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Tell us who will meet us and how to get in at your building near Lochans. We will confirm the plan with the fixed quote.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  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. We apply the specified sealant to the depth and around the services as the detail shows.
  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

Advice

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Lochans can form part of a wider programme across Dumfries and Galloway.

What sets the cost

These are the things that shape the price:

  • Distance, for remote addresses
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • The product your specification calls for
  • What the building is and how it’s used
  • Your programme or deadline
  • Approximate linear metres or a joint schedule

To get a fixed quote, give us a call on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.
