Facade sealing in Innis nan Lìon

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

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Arranging specialist high-level access, which is planned with the client
  • Cracked or spalling substrates that need repair before sealing

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What we seal

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

Facade sealing in Innis nan Lìon

External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We plan for that and keep you updated. If you have unsightly perimeter sealant on a visible elevation and old perimeter mastic that has dried out, we can help, on cladding panel joints, shopfront frames and perimeter joints where frames meet the structure alike. A single leaking joint is often how a building in Innis nan Lìon first comes to us: we look at the rest while we’re there and tell you what we find.

Construction around smaller Scottish places like Innis nan Lìon is often one-off schemes: a school, a health centre, a hotel extension or a few houses. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

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

How the job changes by surface

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, as the specification sets out.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and we’ll mention any edges that need repair.

Sites around Innis nan Lìon get mastic sealed to the drawings and the programme, nothing improvised. Around Innis nan Lìon, as anywhere, a facade joint depends on its sizing, backing rod and preparation.

Owners, agents and contractors

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

Common questions from Innis nan Lìon clients

Is Innis nan Lìon too far out for you?

No. Places such as Innis nan Lìon are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you fit the mastic around our build programme in Innis nan Lìon?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you seal on top of existing sealant?

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

Do you provide access for facade work?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we’ll agree the approach together.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

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.

Quoting for work in Innis nan Lìon

Before we quote, we look at:

  • Which sealant the job calls for
  • Access and working height
  • The size and state of each joint
  • The total length or number of joints

A quote for facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • The site address and postcode
  • When you need the work done
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to speak to us on 01277 525 020 or email drawings and photos with what you know.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Tell us who will meet us and how to get in at your building near Innis nan Lìon. We will confirm the plan with the fixed quote.

  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. 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. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Share your working hours and any access restrictions
  • Move anything stored against the joints
  • Flag any permit to work we will need
