Fire stopping in Collieston

How a job runs

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Collieston, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Agree which areas must stay open
  • Send any specification or drawings in advance
  • Tell us your opening times and when work is allowed

Advice

Fire stopping for commercial buildings in Collieston

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about openings found when ceilings come down for a refit and openings left by services added after handover, across cable penetrations, joints between fire-resisting walls and floors and pipe penetrations. A specialist sealant contractor works differently from a general builder: on jobs in Collieston, preparation and product choice get the time they need.

Travel to smaller places like Collieston is planned so every penetration is sealed on one trip. Send the specification and photographs of the openings, with sizes if you have them.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or send photos by email and we’ll come back to it.

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Writing the fire-stopping specification
  • Construction that lacks the fire resistance the seal relies on
  • Signing off or certifying a building’s fire stopping

If you are not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer.

Surfaces we seal

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

What the job involves on each surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

Cables and cable bundles

New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Where services cross fire walls in Collieston

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, with proprietary products, intumescent ones included, tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

For a building such as Parish Church of Slains, new heating or data runs are the usual reason penetrations need sealing.

What happens if it’s left?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Around smaller places like Collieston, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.

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

Your questions answered

Which Scottish guidance covers penetration seals in Collieston?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

Is a smaller place like Collieston outside your area?

Not at all. Collieston is within our area. We work across every Scottish council area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months on every job.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

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.

Can you quote from photos?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

What we are called out for in Collieston

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.

Look out for the following:

  • Fire stopping installed outside its tested range
  • Fire-stopping items raised at inspection or handover
  • Head-of-wall gaps with no fire seal
  • Openings found when ceilings come down for a refit

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

What your quote should include

  • Will CSCS-carded applicators be on site?
  • What the guarantee covers, and for how long
  • Will failed sealant be removed rather than covered?
  • Their plan for phasing and protecting the area
