Fire stopping for commercial buildings in Sandwick

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 part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal, not a rule of thumb. If you are dealing with unsealed joints where partitions meet the slab and fire seals cut back for extra cables and never reinstated, we can put it right, on small duct penetrations where the tested detail allows, pipe penetrations and cable penetrations alike. For commercial sealant work in Sandwick, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller places such as Sandwick, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Building owners, agents and FMs in Sandwick

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Where services cross fire walls in Sandwick

Being on an island, Sandwick means planning around ferry times as well as the weather. With the specification and photos of the openings, the right fire-rated products travel with us. 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.

Buildings near Sandwick get the fire-rated product that’s specified, installed to its tested detail. Around Sandwick, fire-stopping design belongs to the designer and building control; installation to the specification is our part.

Sandwick is in the Shetland Islands. We cover Sandwick, with the same fixed quotes and 12-month guarantee as everywhere else. Across the Shetland Islands, 63 places are covered, including Sandwick.

If you need fire stopping in ZE2, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Buildings on Central Park, Parklands and Aestbrek are within our area for service penetrations. Nearby places we also cover include Hoswick (1 mile west), Mail (2 miles north), Levenwick (2 miles south-west), Bremirehoull (3 miles north) and Bigton (3 miles south-west) for service penetrations. Further afield, our area takes in Lerwick (11 miles north), Sound (10 miles north) and Scalloway (10 miles north). Sandwick is one of the busier places in the Shetland Islands, and we take on service penetrations for its commercial and public buildings. For island and remote sites, travel and materials need planning ahead, so the full address helps from the start.

How the job changes by surface

Metal pipes

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

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.

Your questions answered

Do you decide the fire-stopping details for buildings in Sandwick?

No. Fire-stopping design and sign-off belong to the designer, principal 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.

How do Scotland’s building standards affect fire-rated sealant in Sandwick?

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.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Can staff carry on working while you’re here?

In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Is your workmanship covered by a guarantee?

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

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

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.

From enquiry to sign-off

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Tell us who will meet us and how to get in at your building near Sandwick. We’ll confirm the plan with the fixed quote.

  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. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Move anything stored against the joints
  • Point out any areas we must not close

Quoting for work in Sandwick

We price every job individually. The main factors are:

  • How much existing material needs removing
  • How much there is to seal
  • Location, for remote and island sites
  • Phasing around occupants

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Approximate linear metres or a joint schedule
  • Specification clauses that apply
  • Any dates the work must fit around
  • Photos of the joints, close up and from further back

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Reviewing a building’s overall fire safety
  • Signing off or certifying a building’s fire stopping
  • Plastic pipes whose detail calls for a collar or wrap

If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.

Surfaces we seal

  • Linear gaps at wall heads
