Fire stopping in Cullivoe

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, give us a call on 01277 525 020 or send details through our quote form with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. Site teams most often ask us about fire sealant pulled out of the opening and service penetrations left open after M&E works, on pipe penetrations, small duct penetrations where the tested detail allows and service gaps in risers. Most enquiries from Cullivoe start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a building near Cullivoe, 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Why deal with it now?

Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Cullivoe, a repair visit takes planning, so it’s better to act early.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Your questions answered

How do the Scottish rules apply to fire-rated sealing in Cullivoe?

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.

Can you produce the fire-stopping design for a job in Cullivoe?

No. The designer or fire engineer sets the detail and building control accepts it. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Can the sealant be colour-matched?

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

Can you quote from photos?

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

What the job involves on each surface

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we will say if that applies.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Fire-rated sealing for Cullivoe buildings

In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, and products should be tested for their end use. We install what’s specified, to the product’s tested detail. Being on an island, Cullivoe means planning around ferry times as well as the weather. With the specification and photographs of the openings, the right fire-rated products travel with us.

Halls and meeting rooms at places like St Olaf's Church sometimes gain new services, and any compartment wall crossed needs the specified seal. Buildings near Cullivoe get the fire-rated product that’s specified, installed to its tested detail.

Cullivoe is in the Shetland Islands. We cover commercial sites throughout Cullivoe. Cullivoe is one of 63 places we cover in the Shetland Islands.

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Fire doors, dampers or other fire safety equipment
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Signing off or certifying a building’s fire stopping

If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer before you book.

Where we work in Cullivoe

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

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • File the specified details where the next contractor can find them
  • Foam or ordinary sealant is never a fire-seal repair
  • Have penetrations checked while they can still be seen
  • Check with the data sheet before painting over fire sealant

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. For work around Cullivoe, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Point out any areas we must not close
  • Send your site hours and access windows
  • Make sure the joints can be reached
