Fire stopping near Scalloway

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

For managing agents and facilities managers

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

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Fire stopping in Scalloway

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. Most enquiries involve expanding foam used as fire stopping and openings left by services added after handover, across joints between fire-resisting walls and floors, cable penetrations and pipe penetrations. For commercial sealant work in Scalloway, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

For a building near Scalloway, we plan fire-rated sealing so it’s finished in one visit where possible. Photos of the gaps, the services and the wall or floor type help us bring the right products.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Cost factors for service penetrations

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • The total length or number of joints
  • Travel to remote or island sites
  • Removal of failed or old sealant
  • Access and working height

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Details that help us quote

Diagnosis starts before we arrive. Tell us:

  • The asbestos register, for older buildings
  • Approximate linear metres or a joint schedule
  • When you need the work done
  • Specification clauses that apply

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Approving the work on behalf of building control
  • Large openings beyond what any sealant detail covers
  • Gaps in walls that were never built as compartment walls

If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Where we work in Scalloway

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

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. 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.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Surface by surface

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.

Service penetrations in Scalloway buildings

Island jobs, Scalloway among them, are planned around the ferry and the forecast. The specification and photographs of each penetration let us bring the right products first time. 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, using products tested for the way they’re used. We install fire-rated sealant to that tested detail where it is specified.

For a building such as Methodist Church, new heating or data runs are the usual reason penetrations need sealing. In a hotel such as Scalloway Hotel (less than half a mile south of Scalloway), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Large healthcare estates like Gilbert Bain Hospital (to the east of Scalloway) change their services often, so penetration seals are worth checking after M&E work.

Scalloway is in the Shetland Islands. Our applicators travel to Scalloway for work on service penetrations. 63 places across the Shetland Islands fall within our area, including Scalloway.

Business premises anywhere in ZE1 are within our area for service penetrations. Buildings on Main Street, Craigpark Road and Meadowfield Road are within our area. Being close to the B9074, Scalloway is easy to get to with materials and equipment. Sites close to Scalloway are covered too, including Gulberwick (2 miles east), Hamnavoe (3 miles south-west), Veensgarth (3 miles north-east), Sound (4 miles east) and Toogs (4 miles south-west).

Your questions answered

Which Scottish guidance covers penetration seals in Scalloway?

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 Scalloway inside the area you cover, given it’s on an island?

Yes. Islands are part of our area, Scalloway included. We group island work where we can and plan around the crossings.

Is any job too small?

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

Can the sealant be colour-matched?

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

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How long does a job like this take?

That varies with the scale of the job, though a typical visit typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building near Scalloway, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification
  • Move anything stored against the joints
