About our facade sealing in Aird Tong

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. If you’re dealing with failed seals around shopfront and entrance frames and cladding panel joints that have opened up, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Aird Tong, that means joint design, primers and backing rod as standard.

Construction around smaller Scottish places like Aird Tong is often one-off schemes: a school, a health centre, a hotel extension or a few houses. The mastic still needs to suit exposed elevations and Scottish weather.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Our process

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Where we can, we combine work around Aird Tong with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints
  • Flag any permit to work we will need

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Aird Tong can sit alongside others in a wider programme across Na h-Eileanan Siar.

What the job involves on each surface

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.

Aird Tong: questions and answers

Will you travel to Aird Tong on the island?

Yes. We work across every Scottish council area, and that includes island locations such as Aird Tong. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Can you take on a job at a hospital such as Western Isles Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Cracked or spalling substrates that need repair before sealing
  • Damp caused by condensation inside the building
  • Joints too narrow for the movement they take, which need redesign

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Where we work in Aird Tong

  • Shopfront frames
  • Coping and flashing joints
  • Cladding panel joints
  • Perimeter joints where frames meet the structure
  • Stone and brick facade joints
  • Window and door perimeters

What happens if it’s left?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. For buildings near Aird Tong, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why us?

  • Standard and matched colours in many product ranges
  • Old sealant cut out, never sealed over
  • CHAS accredited
  • Our applicators hold CSCS cards

Sites and facades in and around Aird Tong

Aird Tong sits close to the coast, within about 1 mile. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Being on an island, Aird Tong means planning around ferry times as well as the weather. Drawings and the programme let us bring every sealant, primer and backing rod the package needs.

On any site in or around Aird Tong, the mastic follows the specification and the programme.

Aird Tong (Gaelic: Aird Thunga) is in Na h-Eileanan Siar. Aird Tong sits inside our coverage and the rest of Na h-Eileanan Siar, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Na h-Eileanan Siar coverage takes in 87 places.

When to call us in Aird Tong

When the sealant tears down its centre, it has usually been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

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

  • Damp patches beside frames after rain
  • Draughts around frames and panels
  • Cladding panel joints that have opened up
  • Perimeter joints where frames meet the structure

Extensions at sites like Western Isles Hospital, 2.6 miles south-west of Aird Tong, usually sit beside working departments, and the mastic follows strict access rules.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Do they follow the manufacturer’s priming guidance?
  • Will failed sealant be removed rather than covered?
  • Who will actually carry out the work
