Fire stopping for commercial buildings in Stornoway

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you have fire-stopping items raised at inspection or handover and non-fire-rated filler around services, we can help, on cable penetrations, small duct penetrations where the tested detail allows and service gaps in risers alike. A single leaking joint is often how a building in Stornoway first comes to us: we look at the rest while we are there and tell you what we find.

For a building near Stornoway, 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.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email us and we will come back to it.

Do you need fire stopping in Stornoway?

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

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

  • Fire stopping installed outside its tested range
  • Unsealed openings around new pipes and cables
  • Head-of-wall gaps with no fire seal
  • Fire sealant pulled out of the opening

Tenant changes at parks like Gleann Seileach Business Park (0.8 miles north-west of Stornoway) bring new data and services, and openings through fire-resisting walls need the specified seal.

How to choose a sealant contractor

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Approving the work on behalf of building control

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly.

Joints and surfaces we work on

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

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • How much existing material needs removing
  • The size and state of each joint
  • Quantities, in metres or numbers
  • Access and working height

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

Whether it’s one area or a whole building, the same details help:

  • Photos of the joints, close up and from further back
  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Access details, including height

For a fixed quote, give us a call on 01277 525 020 or email us, telling us the site location and the nature of the job. You can also send details through our quote form.

Common questions from Stornoway clients

Do you take on work at healthcare sites like Western Isles Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Gleann Seileach Business Park, near Stornoway, within your area?

Yes, sites like Gleann Seileach Business Park are within our area, along with the rest of Stornoway. Photos and a short description are enough for a first look.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Is fire stopping in Scotland covered by different guidance?

Building standards in Scotland are separate from England’s, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

How much does the work cost?

There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Compartments and services around Stornoway

There are several hotels within about 2 miles of Stornoway. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Being on an island, Stornoway 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.

Hotels such as Royal Hotel (under half a mile south-west of Stornoway) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. On a hospital site such as Western Isles Hospital (0.5 miles north of Stornoway), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Stornoway (Gaelic: Steòrnabhagh) is in Na h-Eileanan Siar. Our applicators travel to Stornoway for work on service penetrations, handled exactly as we handle every other area. Our Na h-Eileanan Siar coverage takes in 87 places, large and small.

Postcode districts covered here: HS1 and HS2. If your site is on Barony Square, Bain Square and Grant Square or close by, send details and we will quote for service penetrations.

Close to Stornoway, our area also takes in Plasterfield (1 mile east), Laxdale (1 mile north), Sandwick (1 mile south-east), Steinis (1 mile east) and Newmarket (1 mile north). As one of the bigger centres in Na h-Eileanan Siar, Stornoway has a broad mix of commercial, public and industrial buildings. Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you give us a call on 01277 525 020 or email a schedule or drawings.

What the job involves on each surface

Drylining partitions

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

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Stornoway, we aim for one trip, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Flag any permit to work we’ll need
  • Make sure the joints can be reached
  • Have the specification and drawings to hand
