Facade sealing in Dunnet, done properly
External joints face UV, rain, temperature swings and building movement all year. 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. If you are dealing with facade joints cracked through the middle and unsightly perimeter sealant on a visible elevation, we can put it right. Searching for sealant specialists in Dunnet? We have been sealing commercial buildings since 2005.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Dunnet that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
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.

How the job changes by surface
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.
New build and refits around Dunnet
The sea is no more than about 1 mile from Dunnet. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Projects in Dunnet follow Scotland’s building regulations, with the local authority acting as verifier. The mastic follows the specification that goes with the warrant.
Older buildings in the area around Dunnet, such as Castle of Mey (4.5 miles east of Dunnet), need care when sealed: the product has to suit soft or historic materials. Hotels like Northern Sands Hotel (to the south-west of Dunnet) rarely close for long, so refurbishment mastic is phased floor by floor.
Dunnet is about 7 miles east of Thurso, in Highland. We send applicators to Dunnet for facade joints. Across Highland, 256 places are covered, Dunnet among them.
Work on facade joints is covered throughout KW14, whatever the building. Just outside Dunnet, we also work in Brough (2 miles north), Castletown (3 miles south-west), Scarfskerry (3 miles north-east), Rattar (3 miles north-east) and Murkle (4 miles south-west). 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.
Near you in Dunnet
A little further out are Westside Croft (0.5 miles north-west) and Castle of Mey (4.5 miles east). Open spaces near Dunnet include St John's Loch.
Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Where we can, we combine work around Dunnet with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Preparing the site
- Warn occupants and staff about the work
- Arrange parking or a loading space
- Make sure the joints can be reached

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Cracked or spalling substrates that need repair before sealing
- Movement beyond what any sealant can handle
Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
Surfaces we seal
- Coping and flashing joints
- Stone and brick facade joints
- Window and door perimeters
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Shopfront frames
Owners, agents and contractors
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Dunnet. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Questions about Dunnet
Can being near the sea in Dunnet affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Dunnet off your patch?
No. Places such as Dunnet are covered as much as the big towns. We work across every Scottish council area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What do you charge?
Every job gets its own fixed quote. To get one, ring 01277 525 020 or send photos by email with a description of the work.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Doing it in-house
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Investigate damp beside windows promptly
- Confirm the survey covers external sealants in older buildings
- Avoid patch repairs on failed facade joints
- Avoid harsh cleaners on facade sealant
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.
