Facade sealing across Strathy

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

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

About our facade sealing in Strathy

Facade sealants sit in the sun, rain and frost every day. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. We work on perimeter joints where frames meet the structure, stone and brick facade joints and shopfront frames, and the usual reasons a site gets in touch are failed seals around shopfront and entrance frames and gaps between rainscreen or cladding panels. Whoever orders the work in Strathy, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Strathy that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How the job changes by surface

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex.

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair.

What affects the price in Strathy

What shapes the price:

  • Location, for remote and island sites
  • How much there is to seal
  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first

A quote for facade joints depends on quantities, condition and access. Call for a quote.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • How the joints are reached, and at what height
  • The type of building and who uses it
  • Any specification or named product
  • The postcode of the building

For a fixed quote, call the office on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Travel to smaller Scottish places like Strathy is planned so the job is finished in one visit where possible, 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 both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000

Why deal with it now?

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Around smaller places like Strathy, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

Why us?

  • CSCS-carded applicators
  • Colour options checked against the specified product
  • CHAS accredited contractor
  • Fixed quotes based on photographs, drawings or a visit

Facades, frames and programmes in Strathy

Strathy sits close to the coast, within about 1 mile. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. In Strathy, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. The mastic package follows the approved specification.

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

Strathy is about 17 miles west of Thurso, in Highland. Any commercial site in Strathy is covered, for single jobs and planned programmes alike. Our Highland coverage takes in 256 places.

We take on facade joints across the KW14 postcode area, whatever the building. If your building is just outside Strathy, we cover Portskerra (3 miles east), Melvich (3 miles east), Reay (8 miles east), Am Blàran Odhar (8 miles west) and Forss (13 miles east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you call 01277 525 020 or email a schedule or drawings.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Check the asbestos register before old mastic is disturbed
  • Keep sills, gutters and drainage paths clear
  • Investigate damp beside windows promptly
  • Share access with other external trades

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

Questions about Strathy

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

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 Strathy too far out for you?

Not at all. Strathy is within our area. 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.

Can you find out why a window is leaking?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we’ll be honest about which it is.

Do you use silicone for external joints?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

Do you offer coloured sealant?

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

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.
