Facades, frames and programmes in Kalliness

Kalliness sits close to the coast, within about 1 mile. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Island jobs, Kalliness among them, are planned around the ferry and the forecast. With drawings and the programme in hand, the whole mastic package comes with us.

Window perimeters and facade joints around Kalliness need correct width, depth and backing rod as much as a neat finish.

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in 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 Kalliness are often grouped with others in the same area. Let us know if your dates have any give.

  1. First we review photos, 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. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Point out any areas we must not close
  • Explain the parking and delivery arrangements

Why act early in Kalliness

Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Why us?

  • CHAS accredited contractor
  • One contact handling all your sites
  • Work to your specification and the manufacturer’s guidance
  • Colours confirmed for the specified product

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Kalliness can form part of a wider programme across the Shetland Islands.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

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.

How the job changes by surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building and need a durable external sealant.

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.

What we’re called out for in Kalliness

When the sealant tears down its centre, it has normally 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.

Clients usually get in touch after noticing one or more of the following:

  • Cladding panel joints that have opened up
  • Weathered joints at frame-to-structure perimeters
  • Staining on stone next to old sealant
  • Damp patches beside frames after rain

Sites around Kalliness get mastic sealed to the drawings and the programme, nothing improvised.

What to look for in a quote

  • Their plan for phasing and protecting the area
  • What level of public liability insurance do they hold?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether old or failed sealant will be cut out, not overlaid

Common questions from Kalliness clients

Is Kalliness inside the area you cover, given it’s on an island?

Yes. Islands are part of our area, Kalliness included. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.

Can being near the sea in Kalliness affect the sealant we need?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Do you use silicone for external joints?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, depending on the substrate and the specification.

Do you install glazing systems?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
