Fire stopping near Clachan Seil

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in Clachan Seil, done properly

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations, and the failures we are asked to look at most are seals that don’t match their tested detail and fire sealant pulled out of the opening. Searching for sealant specialists in Clachan Seil? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Hotels and care homes around smaller places like Clachan Seil often have services added during refurbishment. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What sets the cost

We price every job individually. The main factors are:

  • Which sealant the job calls for
  • How much existing material needs removing
  • Backing rod, priming and other preparation
  • Phasing around occupants

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Details that help us quote

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

  • The product your specification calls for
  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours

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 call 01277 525 020 or send photos by email.

Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

How a job runs

We begin with a short walk round with whoever looks after the building, 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. Travel to smaller Scottish places like Clachan Seil is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  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. 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

  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we’ll be in
  • Share the asbestos register for older buildings

Why act early in Clachan Seil

A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. For buildings near Clachan Seil, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Questions about Clachan Seil

How do Scotland’s building standards affect fire-rated sealant in Clachan Seil?

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. Design sits with the designer and the verifier; installation to the tested detail is our part.

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

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

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’ll confirm with the quote.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Do you cover Clachan Seil?

Yes. Sites across Clachan Seil are covered.

How the job changes by surface

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, with no gaps along the run.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
