Fire stopping in Exnaboe, done properly

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. If you are dealing with builders’ foam or ordinary silicone in compartment walls and fire-stopping items raised at inspection or handover, we can put it right. For commercial sealant work in Exnaboe, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Refurbishments in small hotels, schools and care homes around places like Exnaboe can leave gaps around new services. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Fire stopping in Exnaboe: the local picture

Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, 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. Work on Exnaboe has to fit the ferry timetable and the forecast. The specification and photographs of each penetration let us bring the right products first time.

Around Exnaboe, fire-stopping design belongs to the designer and building control; installation to the specification is our part.

Exnaboe is about 19 miles south of Lerwick, in the Shetland Islands. We cover commercial sites throughout Exnaboe. 63 places across the Shetland Islands fall within our area, Exnaboe among them.

What we are called out for in Exnaboe

Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.

If one of these sounds familiar, it’s time for a closer look:

  • Hidden openings found during inspections
  • Unsealed openings around new pipes and cables
  • Old intumescent sealant that has split away
  • Builders’ foam or ordinary silicone in compartment walls

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

Our contractor checklist

Quoting for work in Exnaboe

Each job is priced on its own details. The main factors are:

  • Any access equipment needed
  • Phasing around occupants
  • The site’s rules and procedures
  • Which sealant the job calls for

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

What we need to price the job

There’s no need for a formal survey. A few details are enough to get going:

  • The site address and postcode
  • Specification clauses that apply
  • Access details, including height
  • Clear photos of the problem areas

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or use the quote form if you’d rather talk the job through.

Commercial clients in Exnaboe

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Exnaboe can sit alongside others in a wider programme.

Surface 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

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Issuing fire ratings or certificates for seals
  • Construction that lacks the fire resistance the seal relies on
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.

Surfaces we seal

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

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Tell us who will meet us and how to get in at your building near Exnaboe. That goes into the plan alongside the quote.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  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.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements
  • Flag any permit to work we will need

Getting a fixed quote

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or send photos by email.

FAQs: Exnaboe

What do Scotland’s building standards say about service penetrations in Exnaboe?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. Design sits with the designer and the verifier; installation to the tested detail is our part.

Do you design the fire stopping for buildings in Exnaboe?

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.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
