What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Approving the work on behalf of building control
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Walls or floors that aren’t fire-resisting to begin with

If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Where we work in Moffat

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

Fire stopping in Moffat

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. If you are dealing with openings found when ceilings come down for a refit and fire stopping installed outside its tested range, we can help, on linear gaps at wall heads, cable penetrations and pipe penetrations alike. A single leaking joint is often how a building in Moffat first comes to us: we look at the rest while we’re there and tell you what we find.

Travel to smaller places like Moffat is planned so every penetration is sealed on one trip. Send the specification and photos of the openings, with sizes if you have them.

A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or send photos by email and we’ll arrange a return visit.

Where services cross fire walls in Moffat

There are plenty of hotels within about 2 miles of Moffat. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, and products should be tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail.

Schools such as Moffat Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Hotels such as The Star Hotel (to the south-west of Moffat) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Moffat is about 19 miles north of Dumfries, in Dumfries and Galloway. Looking for fire stopping in Moffat? We can help. Across Dumfries and Galloway, 139 places are covered, Moffat among them. There’s a separate page for Edinburgh, about 43 miles away.

Business premises anywhere in DG10 are within our area for service penetrations. We cover commercial and managed buildings on High Street, Mansfield Place and Star Street. Being close to the A701 and A708, Moffat is easy to get to with materials and equipment. If your building is just outside Moffat, we cover Beattock (2 miles south), Newton Wamphray (7 miles south), Johnstonebridge (8 miles south), Elvanfoot (11 miles north-west) and Crawford (12 miles north-west). Bigger towns within reach include Lockerbie (15 miles south), Lochmaben (14 miles south) and Thornhill (14 miles south-west). As one of the bigger centres in Dumfries and Galloway, Moffat has a broad mix of commercial, public and industrial buildings, and we cover them all.

After the work

For the best life from the joints:

  • Leave fire sealant to cure fully before covering it
  • Agree the fire-stopping specification before services go in
  • Put resealing into every M&E and fit-out package
  • Check risers and ceiling voids after each round of works

During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Signs you need fire stopping in Moffat

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

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

  • Fire sealant pulled out of the opening
  • Openings found when ceilings come down for a refit
  • Non-fire-rated filler around services
  • Openings left by services added after handover

For a hospital such as Moffat Hospital, 0.5 miles east of Moffat, penetration sealing is normally phased ward by ward, with infection-control rules agreed first.

Choosing a commercial sealant contractor

Questions we’re asked in Moffat

Can you seal penetrations in a hotel in Moffat after a refit?

Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Is Moffat too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

How many days will you need on site?

It depends on the scope, but the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we will set out a timescale with the quote.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Joint width, depth and condition
  • The total length or number of joints
  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Where the site is, with the postcode
  • The product your specification calls for
  • When you need the work done
  • Whether the building will be occupied during the work

For a fixed quote, give us a call on 01277 525 020 or send photos by email, telling us the site location and the nature of the job. Our quote form is another easy route.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs near Moffat are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Tell us which areas need to stay in use
  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we’ll be in

Advice

Different surfaces, different methods

Metal pipes

Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
