Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping in Portnahaven

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Portnahaven and nearby. We work on cable penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and the failures we are asked to look at most are expanding foam used as fire stopping and penetration schedules that need working through. One point of contact handles commercial sealant work in Portnahaven from the first photos to the final walk-round, whether it’s one building or several.

For a building near Portnahaven, we plan fire-rated sealing so it’s finished in one visit where possible. Send the specification and photographs of the openings, with sizes if you have them.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Surface by surface

Drylining partitions

Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range.

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.

Diagnose, treat, sign off

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs near Portnahaven are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Let us know about inductions and permits
  • Agree which areas must stay open
  • Arrange parking or a loading space

What affects the price in Portnahaven

The price varies from site to site. Expect it to depend on:

  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first
  • The site’s rules and procedures
  • How accessible the joints are

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • Any specification or named product

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email us.

Portnahaven: questions and answers

Do you decide the fire-stopping details for buildings in Portnahaven?

No, that sits with the designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

How do Scotland’s building standards affect fire-rated sealant in Portnahaven?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What do you charge?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

How many days will you need on site?

It depends on the scope, but the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you need fire stopping in Portnahaven?

A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position and has to be removed.

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

  • Seals disturbed by maintenance and left open
  • Penetration schedules that need working through
  • Expanding foam used as fire stopping
  • Seals that don’t match their tested detail

Around Portnahaven, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Are they CHAS accredited or on Constructionline?
  • The named product and why it was chosen
  • Whether old or failed sealant will be cut out, not overlaid

How to choose a sealant contractor

Looking after the joints

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Put resealing into every M&E and fit-out package
  • Get seals inspected before ceilings and boxing close
  • Check with the data sheet before painting over fire sealant
  • Record which product was used where

Give the sealant its full cure time before ceilings, boxing or decoration go over it. 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 compared with dozens found at once.

Fire-rated sealing for Portnahaven 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 products tested for that end use. We install fire-rated sealant to that tested detail where it is specified.

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

Portnahaven (Gaelic: Port na h-Abhainne) is in Argyll and Bute. Businesses, contractors and managing agents in Portnahaven use us for work on service penetrations. Portnahaven is one of 124 places we cover in Argyll and Bute for service penetrations.

Work on service penetrations is covered throughout PA47, for business premises of every kind. For a building on High Street, Shore Street and Church Street or nearby, send details and we’ll quote for service penetrations. Just outside Portnahaven, we also work in Bun Othan (1 mile south), Port Charlotte (6 miles north-east), Bowmore (10 miles north-east), Imeraval (12 miles east) and Port Ellen (13 miles east). Where a site is remote or on an island, travel and materials need planning ahead, so include the location in your enquiry.
