About our fire stopping in Hairmyres

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. Those on your schedule are closed with the specified product. We work on small duct penetrations where the tested detail allows, pipe penetrations and cable penetrations, and the usual reasons a site gets in touch are fire-stopping items raised at inspection or handover and improvised or mixed-product fire seals. For commercial sealant work in Hairmyres, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In smaller Scottish places like Hairmyres, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Those penetrations are closed with the product the specification names, built up as tested.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Compartments and services around Hairmyres

A 2-mile radius around Hairmyres takes in several hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. 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, with products tested for that end use. We install what’s specified, to the product’s tested detail.

For a school such as Duncanrig Secondary School, penetration sealing fits best at the end of the summer works. At a college such as Jackton Police Training College, less than half a mile to the south-west of Hairmyres, checking penetration seals after summer M&E works is good practice.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Travel to smaller Scottish places like Hairmyres is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions
  • Explain the parking and delivery arrangements

Common questions from Hairmyres clients

How do the Scottish rules apply to fire-rated sealing in Hairmyres?

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 work at a site such as St James Retail Centre, by Hairmyres?

Yes. We cover Hairmyres and the area around it, including industrial estates, business parks and retail parks such as St James Retail Centre. A few photos and the unit address let us price the work.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Is your workmanship covered by a guarantee?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Different surfaces, different methods

Risers and ceiling voids

Voids hide a lot of unsealed openings. We follow your schedule area by area, and note anything we find that isn’t on it.

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.

Why deal with it now?

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Renewing every failing joint on one visit is the sensible approach for a place like Hairmyres. Photos of each area help us quote the whole job.

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

When to call us in Hairmyres

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.

Common reasons buildings call us in:

  • Snag lists that include open service penetrations
  • Fire-rated sealant that has cracked or shrunk back
  • Hidden openings found during inspections
  • Open linear gaps along the top of fire-resisting walls

Refits at places like St James Retail Centre (under half a mile north of Hairmyres) often reroute services through walls between units.

What to look for in a quote

  • How the joint faces will be prepared and primed
  • Their public liability cover
  • The named product and why it was chosen
  • Whether their applicators hold CSCS cards

How to choose a sealant contractor

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Reviewing a building’s overall fire safety
  • Gaps in walls that were never built as compartment walls
  • Writing the fire-stopping specification

If in doubt, call 01277 525 020 or email us and we will say what we think before you book.

Surfaces we seal

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