Fire stopping across Geirinis

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Fire stopping in Geirinis

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you are dealing with seals disturbed by maintenance and left open and head-of-wall gaps with no fire seal, we can help. Whoever orders the work in Geirinis, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Hotels and care homes around smaller places like Geirinis often have services added during refurbishment. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or send details through our quote form and we will arrange a return visit.

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Fire risk assessments, a job for a competent assessor
  • Issuing fire ratings or certificates for seals
  • Writing the fire-stopping specification

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think.

What we seal

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

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Where we can, we combine work around Geirinis with other jobs nearby. Let us know if your dates have any give.

  1. We read the specification, drawings or penetration schedule you send 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. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Have the specification and drawings to hand
  • Make sure the joints can be reached
  • Share the asbestos register for older buildings

Service penetrations in Geirinis buildings

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

Buildings near Geirinis get the fire-rated product that’s specified, installed to its tested detail. For any site around Geirinis, we work to the specification and the manufacturer’s installation guidance, leaving design and sign-off with the designer.

Geirinis (Gaelic: Gerinish) is in Na h-Eileanan Siar. Anywhere in HS8, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 87 places in Na h-Eileanan Siar, from busy centres to rural villages.

We take on service penetrations across the HS8 postcode area, whatever the building. If your site is on Cille Bha'nain and Dun Mor or close by, send details and we will quote for service penetrations. We also cover Creag Ghoraidh (4 miles north), Grimsay (5 miles north-east), Balivanich (8 miles north), Baile a' Mhanaich (8 miles north) and Dalabrog (13 miles south). Where a site is remote or on an island, travel and materials need planning ahead.

Surface by surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness first.

Small ducts

We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.

Questions about Geirinis

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

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.

Do you work on the island where Geirinis is?

Yes. We work across every Scottish council area, and that includes island locations such as Geirinis. We group island work where we can and plan around the crossings.

What will the job cost?

Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or email the details over with a description of the work.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member.

When to bring in a specialist

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.

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.

Cost factors for service penetrations

Each job is priced on its own details. The things that drive the figure:

  • How much existing material needs removing
  • The site’s rules and procedures
  • How accessible the joints are
  • Working within restricted access windows

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • The postcode of the building
  • Access details, including height
  • What the building is and how it’s used
  • When you need the work done

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