About our fire stopping in Hoswick

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we’re called in for most is builders’ foam or ordinary silicone in compartment walls and hidden openings found during inspections. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hoswick, preparation and product choice get the time they need.

Around smaller places such as Hoswick, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. 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. That covers our preparation and application, and if something we did falls short, we return to it.

Hoswick: questions and answers

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

Yes. We work across every Scottish council area, and that includes island locations such as Hoswick. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

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

No, that sits with the designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Treat an open penetration as a priority repair
  • File the specified details where the next contractor can find them
  • Put resealing into every M&E and fit-out package
  • Settle who seals which penetrations at the start of a project

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

Why act early in Hoswick

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Around smaller places like Hoswick, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • Walls or floors that aren’t fire-resisting to begin with
  • Plastic pipes whose detail calls for a collar or wrap
  • Writing the fire-stopping specification

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly.

Joints and surfaces we work on

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

What the job involves on each surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers first.

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.

Service penetrations in Hoswick 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. Our part is installing the specified fire-rated sealant to its tested detail. Work on Hoswick has to fit the ferry timetable and the forecast. With the specification and photographs of the openings, the right fire-rated products travel with us.

Buildings near Hoswick get the fire-rated product that’s specified, installed to its tested detail. Wherever the building is near Hoswick, design and sign-off of fire stopping sit with the designer, fire engineer or building control; we install what has been specified.

Hoswick is about 11 miles south of Lerwick, in the Shetland Islands. If you are looking for fire stopping in Hoswick, we can help, as we do across the Shetland Islands. Hoswick is one of 63 places in the Shetland Islands on our list for service penetrations.

Work on service penetrations is covered throughout ZE2, for business premises of every kind. For a building on Greenfield Road and Brakefield Road or nearby, we can quote for service penetrations. If your building is just outside Hoswick, we cover Sandwick (1 mile east), Levenwick (2 miles south), Bigton (3 miles south-west), Mail (3 miles north) and Bremirehoull (3 miles north). Nearby towns on our patch include Lerwick (11 miles north), Sound (11 miles north) and Scalloway (10 miles north). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, 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 Hoswick. That goes into the plan alongside the 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. 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.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open
  • Tell us what induction or permit system the site runs
