How we handle fire stopping in Mochrum

Facilities managers in Mochrum often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. Most enquiries involve fire sealant pulled out of the opening and unsealed penetrations discovered above suspended ceilings, on service gaps in risers, cable penetrations and joints between fire-resisting walls and floors. Searching for sealant specialists in Mochrum? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Around smaller places such as Mochrum, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What happens if it’s left?

Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable. Around smaller places like Mochrum, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why us?

  • Fully insured
  • CHAS accredited contractor

Common questions from Mochrum clients

Is Mochrum too far out for you?

No. Places such as Mochrum are covered as much as the big towns. We work across every Scottish council area. Good photographs up front let us bring everything on the first visit.

Will you design a fire-stopping scheme for our building in Mochrum?

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.

Is your workmanship covered by a guarantee?

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

Are you fully insured?

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

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

How long does a job like this take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Common problems we fix in Mochrum

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Most enquiries start with something like this:

  • Snag lists that include open service penetrations
  • Builders’ foam or ordinary silicone in compartment walls
  • Damaged fire seals in risers and voids
  • Service penetrations left open after M&E works

Hotels such as Greenmantle Hotel (less than half a mile south of Mochrum) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Questions to ask before you book

  • How joint depth will be controlled
  • Who will actually carry out the work
  • How they handle RAMS and site documents
  • The terms of the workmanship guarantee

Questions to ask before you appoint anyone

From enquiry to sign-off

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Jobs near Mochrum are often grouped with others in the same area. Let us know if your dates have any give.

  1. First we go through the drawings, schedule or specification for the seals.
  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. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work

Where services cross fire walls in Mochrum

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 products tested for that end use. We install fire-rated sealant to that tested detail where it is specified.

For a building such as Kirk of Mochrum, new heating or data runs are the usual reason penetrations need sealing.

Mochrum is about 20 miles south-east of Stranraer, in Dumfries and Galloway. We cover commercial sites throughout Mochrum, whether it’s a single job or part of a planned programme. Mochrum is one of 139 places in Dumfries and Galloway on our list for service penetrations. For work in that direction, see our Glasgow page.

Work on service penetrations is covered throughout DG8, whatever the building. Nearby places we also cover include Elrig (2 miles west), Port William (2 miles south), Monreith (3 miles south), Whauphill (4 miles north-east) and Sorbie (6 miles east). Further afield, our area takes in Newton Stewart (12 miles north), Wigtown (8 miles north-east), Creetown (11 miles north-east), Minnigaff (13 miles north) and Whithorn (7 miles south-east).

Local landmarks in Mochrum

A little further out are Myrton Castle (2.1 miles south-east). The countryside around Mochrum includes White Loch of Myrton and Mochrum Fell.

Different surfaces, different methods

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter.

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
