Facade sealing near Thrumster
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Aftercare for building managers
A few simple habits keep the new joints working:
- Brief window cleaners about newly sealed joints
- Check the asbestos register before old mastic is disturbed
- Walk the elevations once or twice a year
- Keep sills, gutters and drainage paths clear
Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards using a matching sealant.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
About our facade sealing in Thrumster
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. If you have facade joints cracked through the middle and old perimeter mastic that has dried out, we can put it right. Facilities teams, main contractors and managing agents in Thrumster tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For a site around Thrumster, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.
Our workmanship is guaranteed for 12 months, in Thrumster as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Mastic packages on Thrumster sites
Thrumster is within about 1 mile of the coast. 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. Scotland has its own building regulations, and in Thrumster warrants come from the local authority verifier. The mastic package follows the approved specification.
Extensions at sites like Wick Town and County Hospital, 3.2 miles north-east of Thrumster, normally sit beside working departments, and the mastic follows strict access rules.
Thrumster is about 20 miles south-east of Thurso, in Highland. Across the KW1 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Highland, 256 places are covered, including Thrumster.
We take on facade joints across the KW1 postcode area, whatever the building. Streets here include Finlayson Place, Bella Mackay Place and Stewart Crescent. If your building is just outside Thrumster, we cover Whiterow (3 miles north-east), Haster (4 miles north), Wick (4 miles north-east), Staxigoe (5 miles north-east) and Ackergillshore (6 miles north). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you speak to us on 01277 525 020 or email drawings and photos.

For rail, the closest station is Wick station, about 3.8 miles north. Other landmarks nearby include Wick Heritage Museum (3.8 miles north-east) and Wick Town and County Hospital (3.2 miles north-east). The countryside around Thrumster includes Loch Hempriggs.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. For work around Thrumster, 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.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Getting the site ready
- Have the specification and drawings to hand
- Share your working hours and any access restrictions
- Agree which areas must stay open

Cost factors for facade joints
We price every job individually. The things that drive the figure:
- Working within restricted access windows
- Any access equipment needed
- Travel to remote or island sites
- The total length or number of joints
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- The postcode of the building
- The asbestos register, for older buildings
- What the building is and how it’s used
- How the joints are reached, and at what height
To get a fixed quote, give us a call on 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.
Questions about Thrumster
Is Thrumster too small for you to travel to?
Not at all. Thrumster is within our area. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.
Would you work within a site like Wick Town and County Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you seal facades in winter?
Rain and frost can pause external sealing. We plan for weather and keep you updated throughout the job.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.
Can you just add new sealant on top?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. That is what makes the new joint last.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
What we’re called out for in Thrumster
When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.
Site and facilities staff are often the first to spot these:
- New sealant peeling off old mastic
- Gaps between rainscreen or cladding panels
- Water coming in around window frames
- Weathered facade joints that have lost their grip
Sites around Thrumster get mastic sealed to the drawings and the programme, nothing improvised.
What your quote should include
- Their public liability cover
- Health and safety accreditation such as CHAS
- How the joint faces will be prepared and primed
- Can the work be phased to keep areas open?
Why act early in Thrumster
Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. For buildings near Thrumster, dealing with all the failing joints at once saves return trips. Send photographs and we’ll quote for everything together.
Pricing facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Different surfaces, different methods
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, often a low-modulus silicone or hybrid.
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.
