Fire stopping for businesses in Greenigoe

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What sets the cost

These are the things that shape the price:

  • How accessible the joints are
  • The total length or number of joints
  • Distance, for remote addresses
  • Whether old sealant has to be cut out first

There’s no price list, since every building and every scope is different. Call for a quote.

What to include in your enquiry

A good diagnosis starts with the right details. Let us know:

  • Any specification or named product
  • Whether the building will be occupied during the work
  • Your programme or deadline
  • How the joints are reached, and at what height

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

How we handle fire stopping in Greenigoe

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. Those on your schedule are closed with the specified product. If you are dealing with openings left by services added after handover and openings found when ceilings come down for a refit, we can help. A single leaking joint is often how a building in Greenigoe first comes to us: we look at the rest while we’re there and tell you what we find.

Around smaller places such as Greenigoe, 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.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Fire risk assessments, a job for a competent assessor
  • Construction that lacks the fire resistance the seal relies on
  • Deciding what a wall or floor needs, which belongs to the designer

If you are not sure, just phone 01277 525 020 or email us and we will give you a straight answer.

Where we work in Greenigoe

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

Doing it in-house

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

On site: what to expect

Tell us your site hours and access windows and we will 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. Where we can, we combine work around Greenigoe with other jobs nearby. Let us know if your dates have any give.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  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. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Have the specification and drawings to hand

Fire stopping around Greenigoe: what changes locally

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 products tested for that end use. We install fire-rated sealant to that tested detail where it is specified. For an island location such as Greenigoe, work is planned around ferry crossings and the weather. The specification and photos of each penetration let us bring the right products first time.

Hospital estates such as Balfour Hospital (to the north-east of Greenigoe) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Around Greenigoe, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.

Greenigoe is about 3 miles south-west of Kirkwall, in the Orkney Islands. Commercial clients in Greenigoe use us for work on service penetrations. Greenigoe is one of 51 places we cover in the Orkney Islands.

We take on service penetrations across the KW15 postcode area, whatever the building. We also cover Blackhill (2 miles north), Kirkwall (3 miles north-east), Kirbister (3 miles west), Grimbister (4 miles north-west) and Orphir (5 miles west). Where a site is remote or on an island, travel and materials need planning ahead, so include the location in your enquiry.

Around Greenigoe

Other landmarks nearby include Kirkwall Castle (2.8 miles north-east) and Orkney Museum (2.8 miles north-east). The countryside around Greenigoe includes Wideford Hill and Lochs of Griffyelt.

Questions we’re asked in Greenigoe

Will you travel to Greenigoe on the island?

Yes, Greenigoe is within the area we cover. Our area covers all of Scotland, cities, towns and islands alike. Ferry times and the weather set the plan, so we ask for photos and a full list first.

Which Scottish guidance covers penetration seals in Greenigoe?

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. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

Can the sealant be colour-matched?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Surface by surface

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.

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.

Looking after the joints

For the best life from the joints:

  • Get seals inspected before ceilings and boxing close
  • Include service cupboards in routine inspections
  • Put resealing into every M&E and fit-out package
  • Agree the fire-stopping specification before services go in

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
