Fire stopping for Dumfries sites

Fire stopping for commercial buildings in Dumfries

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. If you are dealing with service penetrations left open after M&E works and head-of-wall gaps with no fire seal, we can put it right, on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and service gaps in risers alike. Most enquiries from Dumfries start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

After refits and M&E works in buildings around Dumfries, gaps around new services are a common finding. If fire-rated sealant is the named product, it is installed as tested; if the detail needs a different item, we will point that out.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What we’re called out for in Dumfries

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

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

  • Fire-rated sealant that has cracked or shrunk back
  • Fire seals cut back for extra cables and never reinstated
  • Penetration schedules that need working through
  • Expanding foam used as fire stopping

For a unit at a site such as St. Mary's Industrial Estate, under half a mile north-east of Dumfries, new power or data runs between office and warehouse can breach a compartment wall.

Before you book anyone

  • How the joint faces will be prepared and primed
  • How long is the guarantee, and what does it include?
  • Who will actually carry out the work
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

Cost factors for service penetrations

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Backing rod, priming and other preparation
  • The total length or number of joints
  • Which sealant the job calls for
  • Location, for remote and island sites

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • When you need the work done
  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Fire stopping around Dumfries: points for this area

A 2-mile radius around Dumfries takes in several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. 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 products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

Hotels such as Queensberry Hotel, less than half a mile south of Dumfries, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Workshops and IT rooms at colleges like Dumfries & Galloway College - Dumfries Campus, 1.8 miles south-east of Dumfries, are re-serviced often, leaving penetrations to seal.

Dumfries is in Dumfries and Galloway. Our applicators travel to Dumfries for work on service penetrations, handled exactly as we handle every other area. Our Dumfries and Galloway coverage takes in 139 places. We also cover Glasgow, some 60 miles away.

Anyone looking for fire stopping in DG1 and DG2 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Industrial estates and retail parks around towns like Dumfries usually have yard space and site rules. Town-centre premises may need parking planned.

  1. First we go through the drawings, schedule or specification for the seals 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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Tell us which areas need to stay in use
  • Let us know about inductions and permits
  • Make sure the joints can be reached

Surface by surface

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits.

When something else is needed

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

  • Fire risk assessments, a job for a competent assessor
  • Plastic pipes whose detail calls for a collar or wrap
  • Construction that lacks the fire resistance the seal relies on

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

What we seal

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

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. A leaking joint can damage finishes, stock and fittings inside. Putting it right early limits the damage.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

FAQs: Dumfries

Do you seal service penetrations in hotels around Dumfries?

Yes, where the specification calls for fire-rated sealant. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

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

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.

Can you quote from photographs?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you work in Dumfries?

Yes. We cover Dumfries, and the simplest way to start is to give us a call on 01277 525 020 or email a schedule or drawings.

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.

Is the work guaranteed?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
