Fire stopping across Addiewell

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

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 we will confirm the paperwork you need with the quote.

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.

About our fire stopping in Addiewell

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. Site teams most often ask us about expanding foam used as fire stopping and unsealed penetrations discovered above suspended ceilings, on service gaps in risers, linear gaps at wall heads and cable penetrations. Whoever orders the work in Addiewell, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a building near Addiewell, 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.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Leave it or put it right?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Questions about Addiewell

Is Addiewell too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What do Scotland’s building standards say about service penetrations in Addiewell?

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. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Is it fine to apply new sealant on top of old?

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

What do you charge?

It depends on the job: quantities, access, the product and any phasing. Call for a quote.

Can staff carry on working while you are here?

Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Quoting for work in Addiewell

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • How accessible the joints are
  • Whether the work must be split into stages
  • Quantities, in metres or numbers
  • Which sealant the job calls for

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Any specification or named product

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call 01277 525 020 or email a schedule or drawings.

How the job changes by surface

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically and tell you about openings outside the list.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.

What we’re called out for in Addiewell

Openings in fire-resisting walls typically appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

Clients typically get in touch after noticing something like this:

  • Fire stopping installed outside its tested range
  • Openings found when ceilings come down for a refit
  • Fire-stopping items raised at inspection or handover
  • Expanding foam used as fire stopping

On a site such as West Calder Business Centre, which lies east of Addiewell, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • What site paperwork they can supply
  • Their pre-qualification and accreditations
  • Their plan for phasing and protecting the area

Questions to ask before you appoint anyone

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. Travel to smaller Scottish places like Addiewell is planned so the job is finished in one visit where possible, which is why we ask for photographs 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.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Arrange parking or a loading space
  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance
