Fire stopping in Symbister, done properly

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations, and what we’re called in for most is builders’ foam or ordinary silicone in compartment walls and unsealed joints where partitions meet the slab. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Symbister is the same: the right product in a properly prepared joint.

In smaller Scottish places like Symbister, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Those penetrations are closed with the product the specification names, built up as tested.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Why it’s worth doing now in Symbister

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Symbister, a repair visit takes planning, so it’s better to act early.

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 when you are ready.

Building owners, agents and FMs in Symbister

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Symbister can form part of a wider programme across the Shetland Islands.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Our process

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Travel to smaller Scottish places like Symbister is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand

Different surfaces, different methods

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.

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.

When to call us in Symbister

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.

Any of the following is a good reason to get the joints checked over:

  • Fire-rated sealant that has cracked or shrunk back
  • Seals that don’t match their tested detail
  • Open linear gaps along the top of fire-resisting walls
  • Hidden openings found during inspections

For any site around Symbister, we work to the specification and the manufacturer’s installation guidance, leaving design and sign-off with the designer.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • Who will actually carry out the work
  • Their approach to joint depth and backing
  • Which product they’ll use, and why it suits the joint

Fire stopping around Symbister: how the place shapes the job

Island jobs, Symbister among them, are planned around the ferry and the forecast. With the specification and photographs of the openings, the right fire-rated products travel with us. 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, using products tested for the way they’re used. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

For buildings in and around Symbister, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

Quoting for work in Symbister

Quotes vary with the job. It mainly depends on:

  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • Quantities, in metres or numbers
  • Specialist products, such as fire-rated or hygienic sealants

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Whether an asbestos survey exists
  • Specification clauses that apply
  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Symbister: questions and answers

Will you travel to Symbister on the island?

Yes, Symbister is within the area we cover. Every Scottish council area is within our area. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

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

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

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Does weather matter for sealant work?

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

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.
