Facade sealing in Cairston

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing in Cairston, done properly

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. We work on shopfront frames, coping and flashing joints and perimeter joints where frames meet the structure, and what we are called in for most is water coming in around window frames and air leaks through failed facade joints. Whoever orders the work in Cairston, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Sites near smaller places like Cairston can mean longer travel, so the mastic is planned with as few trips as the job allows. Send drawings, photos and the programme so everything needed arrives on the first day.

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

What happens if it’s left?

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice. Around smaller places like Cairston, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

How the job changes by surface

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and areas needing repair are flagged.

Cladding panel joints

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

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Contractors’ notes for Cairston

With the shore within about 1 mile, Cairston counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. Projects in Cairston follow Scotland’s building regulations, with the local authority acting as verifier. The mastic follows the specification that goes with the warrant.

On a campus such as Robert Gordon University Orkney Project, 1.4 miles south-west of Cairston, new teaching buildings and residences are typically built and refurbished around the academic year. Projects at schools like stromness primary school work to term dates, so mastic is programmed tightly.

Cairston is about 11 miles west of Kirkwall, in the Orkney Islands. Cairston sits inside our coverage and the rest of the Orkney Islands, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 51 places across the Orkney Islands fall within our area, including Cairston.

Postcode districts covered here: KW16 for facade joints. Sites close to Cairston are covered too, including Stromness (1 mile south-west), Clouston (2 miles east), Stenness (2 miles east), Wasbister (3 miles north) and Grimeston (4 miles north-east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

What we are called out for in Cairston

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

These are often picked up first by site or facilities staff:

  • Failed seals around shopfront and entrance frames
  • Unsightly perimeter sealant on a visible elevation
  • Previous reseals run over old sealant
  • Leaks at window and door perimeters

Hotels like The Stromness Hotel (1.4 miles south-west of Cairston) rarely close for long, so refurbishment mastic is phased floor by floor.

Questions about Cairston

Our building in Cairston is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Do you work on the island where Cairston is?

Yes, Cairston is within the area we cover. We cover the whole of Scotland. Ferry times and the weather set the plan, so we ask for photographs and a full list first.

How do we ask for a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email the details over. Include photographs or drawings if you have them.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we’ll set out a timescale with the quote.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Looking after the joints

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

  • Share access with other external trades
  • Investigate damp beside windows promptly
  • Insist on a full cut-out when joints are renewed
  • Keep the sealant details on the building file

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade rather than sitting against the joints.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Cairston, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Getting the site ready

  • Point out parking and an unloading spot
  • Move anything stored against the joints
  • Let us know about inductions and permits
