Questions we are asked in Brèibhig

Can you work on a hospital site such as St Brendan's Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you travel to Brèibhig on the island?

Yes. We cover the whole of Scotland, and that includes island locations such as Brèibhig. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Can you work plot by plot or floor by floor?

Our work is sequenced around the programme. Areas are sealed as they’re released by the site team.

Do you install fire-rated sealant as part of a package?

It can be part of the package where specified. Record requirements are confirmed at quote stage.

Will you stick to the specified products?

We work to the specification and the manufacturer’s installation guidance. Primers, backing and joint depth follow what the manufacturer sets out.

About our construction mastic in Brèibhig

Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place, and one applicator team gives a consistent finish. Most enquiries involve frame perimeters left unsealed or poorly sealed and external joints sealed in damp or cold conditions that are now failing, on floor and skirting junctions, brick and block movement joints and cladding and panel joints. One point of contact handles commercial sealant work in Brèibhig from the first photos to the final walk-round, whether it’s one building or several.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Brèibhig that means watching the forecast. We build some give into the plan and agree it with the site manager.

The 12-month guarantee covers our workmanship: 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

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Approving fire stopping as compliant
  • Specifying the product where the designer hasn’t
  • Faulty frames rather than failed sealant

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

What we seal

  • Window and door perimeters
  • Internal decorators’ caulk
  • Brick and block movement joints
  • Floor and skirting junctions
  • Cladding and panel joints
  • Sanitary and kitchen joints

General trades versus a specialist

Redoing a failed joint usually costs more than getting it right at the outset, 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.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

What sets the cost

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

  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits
  • The size and state of each joint

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Where the site is, with the postcode
  • Your programme or deadline
  • Any specification or named product
  • The asbestos register, for older buildings

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

When to call us in Brèibhig

Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.

Most enquiries start with something like this:

  • Frame gaps too wide for sealant alone
  • Existing joints on a refurb that need cutting out and resealing
  • Mastic snags holding up handover
  • Different trades sealing to different standards

Hotel extensions and refits, at places such as Craigard Hotel (1.3 miles west of Brèibhig), typically run between busy periods, so the sealing is squeezed into short windows.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • How long is the guarantee, and what does it include?
  • How the joint faces will be prepared and primed
  • Their pre-qualification and accreditations

Our contractor checklist

Our process

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs near Brèibhig are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Getting the site ready

  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work

Advice

Surface by surface

Fire-rated sealant where specified

Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control.

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.

New build and refits around Brèibhig

Brèibhig is within about 1 mile of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. Work on Brèibhig has to fit the ferry timetable and the forecast. We need drawings and a programme early so materials come on the right crossing.

Extensions at sites like St Brendan's Hospital, 1.8 miles west of Brèibhig, normally sit beside working departments, and the mastic follows strict access rules. When a school such as Castlebay Community School is extended or refurbished, the mastic package is often squeezed into the holidays.
