Facade sealing near Aird

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What we are called out for in Aird

Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

Most enquiries start with one or more of the following:

  • Weathered facade joints that have lost their grip
  • Air leaks through failed facade joints
  • Leaks at window and door perimeters
  • Facade joints cracked through the middle

Projects at schools like Aird Primary School work to term dates, so mastic is programmed tightly.

What your quote should include

  • How they’ll work around occupants
  • Whether old or failed sealant will be cut out, not overlaid
  • What level of public liability insurance do they hold?
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

Facade sealing in Aird

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. We work on cladding panel joints, perimeter joints where frames meet the structure and stone and brick facade joints, and the usual reasons a site gets in touch are facade joints cracked through the middle and old perimeter mastic that has dried out. A specialist sealant contractor works differently from a general builder: in Aird, that means joint design, primers and backing rod as standard.

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

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What sets the cost

Quotes vary with the job. It mainly depends on:

  • The product specified
  • How much there is to seal
  • Travel to remote or island sites
  • Whether old sealant has to be cut out first

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • Any dates the work must fit around
  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Why deal with it now?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. For buildings near Aird, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why clients in Aird choose us

  • Work carried out by CSCS-carded applicators
  • Colours confirmed for the specified product
  • Old sealant cut out, never sealed over
  • RAL and finish matching where the product range allows

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building near Aird, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Tell staff and tenants when we will be in
  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

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.

Aird: questions and answers

Can you take on a job in Aird, on the island?

Yes. Islands are part of our area, Aird included. We group island work where we can and plan around the crossings.

Will you fit the mastic around our build programme in Aird?

Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

What do you charge?

Every job gets its own fixed quote. For yours, call 01277 525 020 or email a schedule or drawings.

Is colour matching possible?

That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Is the work guaranteed?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

Do you seal facades in winter?

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.
