Facade sealing across Keyhead

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

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Render or concrete edges that have broken away
  • Damp caused by condensation inside the building
  • Work on the window or framing system itself

If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

What we seal

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

Facade sealing in Keyhead, done properly

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. We work on cladding panel joints, perimeter joints where frames meet the structure and stone and brick facade joints, and the failures we’re asked to look at most are weathered facade joints that have lost their grip and sealant pulling away from frames or panels. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Keyhead, that means joint design, primers and backing rod as standard.

In smaller places such as Keyhead, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

We sign every job 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.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Record the product and colour used on each elevation
  • Avoid harsh cleaners on facade sealant
  • Insist on a full cut-out when joints are renewed
  • Add perimeter sealant to planned maintenance checks

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Where we can, we combine work around Keyhead with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot

Related advice

Surface by surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.

FAQs: Keyhead

Does a coastal location like Keyhead affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Is Keyhead off your patch?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

What do you charge?

Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or email drawings and photos.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

Do you run new sealant over the existing bead?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Cost factors for facade joints

What shapes the price:

  • Phasing around occupants
  • How accessible the joints are
  • Joint width, depth and condition
  • Induction, permit and paperwork requirements

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Specification clauses that apply
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours
  • The asbestos register, for older buildings

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or email drawings and photos.

Facades, frames and programmes in Keyhead

Keyhead is within about 3 miles of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Being in the east of Scotland, Keyhead gets less rain than the west coast. Frosty spells still affect external mastic dates. We agree external dates with the site team and keep internal work ready.

Window perimeters and facade joints around Keyhead need correct width, depth and backing rod as much as a neat finish. On any site in or around Keyhead, the mastic follows the specification and the programme.
