Fire stopping for businesses in Harray

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

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Location, for remote and island sites
  • The total length or number of joints
  • How much existing material needs removing
  • The site’s rules and procedures

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Your programme or deadline
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode
  • The asbestos register, for older buildings

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Fire stopping in Harray, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. Most enquiries involve seals that don’t match their tested detail and unsealed openings around new pipes and cables, across small duct penetrations where the tested detail allows, pipe penetrations and cable penetrations. One point of contact handles commercial sealant work in Harray from the first photographs to the final walk-round, whether it’s one building or several.

Hotels and care homes around smaller places like Harray often have services added during refurbishment. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

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

Fire-rated sealing for Harray buildings

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. Our part is installing the specified fire-rated sealant to its tested detail. For an island location such as Harray, work is planned around ferry crossings and the weather. With the specification and photos of the openings, the right fire-rated products travel with us.

Older community buildings such as Grimeston Congregational Chapel that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Harray is about 9 miles north-west of Kirkwall, in the Orkney Islands. Across the KW17 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 51 places in the Orkney Islands, large and small.

Business premises anywhere in KW17 are within our area for service penetrations. Nearby places we also cover include Bimbister (1 mile south), Russland (1 mile west), Grimeston (2 miles south), Hourston (2 miles north-west) and Wasbister (3 miles south-west). For island and remote sites, we plan travel and materials carefully.

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Writing the fire-stopping specification
  • Construction that lacks the fire resistance the seal relies on
  • Fire doors, dampers or other fire safety equipment

If you’re not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Questions we are asked in Harray

Which Scottish guidance covers penetration seals in Harray?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Can you take on a job in Harray, on the island?

Yes. We work across every Scottish council area, and that includes island locations such as Harray. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you work while the building is occupied?

Usually, yes. Phased work can be planned so areas stay in use.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For a building near Harray, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Related advice

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Foam or ordinary sealant is never a fire-seal repair
  • File the specified details where the next contractor can find them
  • Treat an open penetration as a priority repair
  • Have penetrations checked while they can still be seen

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Signs you need fire stopping in Harray

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.

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

  • Fire-stopping items raised at inspection or handover
  • Damaged fire seals in risers and voids
  • Unsealed penetrations discovered above suspended ceilings
  • Seals that don’t match their tested detail

Buildings near Harray get the fire-rated product that’s specified, installed to its tested detail.

What to look for in a quote

  • Proof of insurance
  • Whether their applicators hold CSCS cards
  • How the existing material will be dealt with
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
