Fire stopping near Potarch

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a building near Potarch, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Warn occupants and staff about the work
  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints

How we handle fire stopping in Potarch

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on pipe penetrations, small duct penetrations where the tested detail allows and service gaps in risers, and the failures we’re asked to look at most are head-of-wall gaps with no fire seal and seals that don’t match their tested detail. Whether you call it commercial sealant work, mastic application or joint sealing, in Potarch it comes down to the same thing: the right product in a properly prepared joint.

For a building near Potarch, we plan fire-rated sealing so it’s finished in one visit where possible. Send the specification and photographs of the openings, with sizes if you have them.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Common problems we fix in Potarch

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in.

It’s worth sending us details if you spot any of the following:

  • Snag lists that include open service penetrations
  • Expanding foam used as fire stopping
  • Service penetrations left open after M&E works
  • Fire stopping installed outside its tested range

For a hospital such as Kincardine O'Neil Hospital, which lies north-west of Potarch, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

Questions to ask before you appoint anyone

Potarch: questions and answers

Can you take on a job at a hospital such as Kincardine O'Neil Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Which Scottish guidance covers penetration seals in Potarch?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can staff carry on working while you’re here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Do your applicators hold CSCS cards?

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

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Should maintenance staff do it?

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Flag new cables with no seal around them
  • Ask the designer to confirm details early on refits
  • Include service cupboards in routine inspections
  • Have penetrations checked while they can still be seen

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Where services cross fire walls in Potarch

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, using products tested for the way they’re used. We install fire-rated sealant to that tested detail where it is specified.

Buildings near Potarch get the fire-rated product that’s specified, installed to its tested detail.

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Gaps in walls that were never built as compartment walls
  • Fire doors, dampers or other fire safety equipment
  • Approving the work on behalf of building control

If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think.

What we seal

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

Cost factors for service penetrations

Your fixed quote is built from the real scope. It allows for:

  • How much existing material needs removing
  • Whether the work must be split into stages
  • The product specified
  • Joint width, depth and condition

A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

What to include in your enquiry

We can often quote from photographs and a few details. It helps to include:

  • The type of building and who uses it
  • The asbestos register, for older buildings
  • Access details, including height
  • When you need the work done

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or send details through our quote form.
