Thurso: questions and answers
Would you work within a site like Dunbar Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you fit the mastic around our build programme in Thurso?
Yes, we work to the programme and the sequence the site sets. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you look at water coming in around a frame?
Yes. Photos help, and you can call the office on 01277 525 020 or send details through our quote form to arrange a visit. Many frame leaks are sealant failures, though not all, and we’ll be honest about which it is.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you install glazing systems?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
How we handle facade sealing in Thurso
Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. If you’re dealing with hard, chalky sealant that no longer flexes and perimeter joints where frames meet the structure, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Thurso is the same: the right product in a properly prepared joint.
Scottish towns such as Thurso see new housing, schools and health centres alongside work on older stone and harled buildings. The mastic package changes with the building: harl and render on some, cladding and brick on others.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Facades, frames and programmes in Thurso
With the shore within about 1 mile, Thurso counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Thurso is in the east of Scotland, which is drier than the west. Frosty spells still affect external mastic dates. We programme around it with the site team.
Hotels like Station Hotel, under half a mile to the south-east of Thurso, rarely close for long, so refurbishment mastic is phased floor by floor. Hospital estates such as Dunbar Hospital, 0.8 miles south-west of Thurso, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Thurso is in Highland. We cover commercial sites throughout Thurso. Thurso is one of 256 places we cover in Highland.
Anyone looking for facade sealing in KW14 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. For a building on Sir John's Square, Gerry Square and High Street or nearby, send details and we’ll quote for facade joints. Thurso sits on or close to the A9 and A836, useful when we plan access and materials. Sites close to Thurso are covered too, including Scrabster (2 miles north-west), Glengolly (2 miles south-west), Janetstown (3 miles south-west), Murkle (3 miles east) and Forss (4 miles west). As one of the bigger centres in Highland, Thurso has a broad mix of commercial, public and industrial buildings, and we cover them all. Where a site is remote or on an island, travel and materials need planning ahead, so the full address helps from the start.
Near you in Thurso
Thurso has its own railway station: Thurso station. A little further out are Scrabster Castle (0.7 miles north-west) and Thurso Heritage Museum (0.6 miles north-west).
Do you need facade sealing in Thurso?
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
Clients usually get in touch after noticing something like this:
- Staining on stone next to old sealant
- Cladding panel joints that have opened up
- Perimeter joints where frames meet the structure
- Previous reseals run over old sealant
Projects at schools like Thurso High School work to term dates, so mastic is programmed tightly.
What to look for in a quote

- What site paperwork they can supply
- What level of public liability insurance do they hold?
- Whether their applicators hold CSCS cards
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. In a Scottish town such as Thurso, outside work is planned around the weather and inside work around the occupants. Send photos or drawings and we will quote and plan to suit.
- We start with photos, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
What we need from you
- For older buildings, check the asbestos register before work
- Point out any areas we must not close
- Send your site hours and access windows

Quoting for work in Thurso
We price every job individually. The things that drive the figure:
- Induction, permit and paperwork requirements
- Joint width, depth and condition
- Whether old sealant has to be cut out first
- Working within restricted access windows
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- When you need the work done
- Specification clauses that apply
- Whether an asbestos survey exists
- Where the site is, with the postcode
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to phone 01277 525 020 or send photos by email.
Why act early in Thurso
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. If one joint has failed on a building in Thurso, its neighbours, laid at the same time, may not be far off. One programme for all of them saves time.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
What you get with us
- A Constructionline member, so easy to vet
- A range of standard colours, depending on the product
- Our applicators hold CSCS cards
- Colour agreed before work starts

Different surfaces, different methods
Window and door perimeters
Frame materials vary, and so does the preparation. Primer goes on where the manufacturer specifies it for that substrate.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Providing access systems for the work
- Damp caused by condensation inside the building
- Damaged frames that need replacing
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly before you book.
