Common questions from Little Dunkeld clients

Is a smaller place like Little Dunkeld outside your area?

Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.

Does your area include sites such as Birnam Industrial Estate, near Little Dunkeld?

Yes. Estates, retail parks and business parks around Little Dunkeld, Birnam Industrial Estate among them, are all within reach. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Can you quote from photos?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Is the BS 476 change in 2029 relevant to fire stopping?

In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029. The European route, BS EN 13501-2, then applies. Your designer will choose products with the right evidence.

Is colour matching possible?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How we handle fire stopping in Little Dunkeld

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Most enquiries involve unsealed penetrations discovered above suspended ceilings and fire stopping installed outside its tested range, across cable penetrations, linear gaps at wall heads and service gaps in risers. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Little Dunkeld, preparation and product choice get the time they need.

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

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Signing off or certifying a building’s fire stopping
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Surfaces we seal

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

Cost factors for service penetrations

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Which sealant the job calls for
  • Location, for remote and island sites
  • How accessible the joints are
  • The total length or number of joints

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • How the joints are reached, and at what height
  • Clear photographs of the problem areas
  • Whether the building will be occupied during the work
  • Specification clauses that apply

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or send photos by email.

Different surfaces, different methods

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.

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.

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Little Dunkeld, we aim for one trip, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Flag any permit to work we’ll need
  • Tell us your opening times and when work is allowed

Where services cross fire walls in Little Dunkeld

The area within 2 miles of Little Dunkeld holds several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. 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.

In a building such as Little Dunkeld Parish Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a unit at a site such as Birnam Industrial Estate, less than half a mile to the south-east of Little Dunkeld, new power or data runs between office and warehouse can breach a compartment wall. For a hotel such as Birnam Hotel, which lies south-east of Little Dunkeld, penetration seals are worth checking after any refit or services upgrade.

Why act early in Little Dunkeld

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Around smaller places like Little Dunkeld, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.

Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
