Facade sealing in Ardheisker

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

Facade sealing in Ardheisker

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, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. If you are dealing with failed sealant on precast panel joints and hard, chalky sealant that no longer flexes, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ardheisker, that means joint design, primers and backing rod as standard.

Sites near smaller places like Ardheisker can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

How a job runs

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Ardheisker, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed
  • Let building users know which areas are affected

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Replacing glass or failed glazing units
  • Joints too narrow for the movement they take, which need redesign
  • Damp caused by condensation inside the building

If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think.

Joints and surfaces we work on

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

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Whether old sealant has to be cut out first
  • Location, for remote and island sites
  • How much there is to seal
  • Backing rod, priming and other preparation

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • Clear photographs of the problem areas
  • Any specification or named product
  • Whether the building will be occupied during the work
  • The site address and postcode

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or use the quote form if you’d rather talk the job through.

Your questions answered

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

Yes, Ardheisker is within the area we cover. We work across every Scottish council area. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.

Can you work to our programme on a site in or near Ardheisker?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you work on upper floors?

We agree access with the client at the start. Let us know what access is in place or planned.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Which sealant do you use on facades?

The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Facade sealing around Ardheisker: what changes locally

Ardheisker sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. For an island location such as Ardheisker, work is planned around ferry crossings and the weather. With drawings and the programme in hand, the whole mastic package comes with us.

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

What we are called out for in Ardheisker

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.

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

  • Sealant pulling away from frames or panels
  • Hard, chalky sealant that no longer flexes
  • Cladding panel joints that have opened up
  • Patch repairs that keep failing

For contractors building in or near Ardheisker, we seal to the drawings, the specification and the programme.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • Whether old or failed sealant will be cut out, not overlaid
  • How the joint faces will be prepared and primed
  • How they handle RAMS and site documents

Choosing a commercial sealant contractor

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Don’t wait for a second leak before calling
  • Check the asbestos register before old mastic is disturbed
  • Add perimeter sealant to planned maintenance checks
  • Plan facade sealing alongside redecoration

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.

Why act early in Ardheisker

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
