External & façade joints in Dunecht, Aberdeenshire
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Dunecht. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
- Brick movement joints where the sealant has split
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Make sure movement joints are not pointed over
- Clear growth from the base of walls and joints
- Keep high-pressure jets off the joints
- Point out the joints to other trades
Do not paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
External mastic in Dunecht
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. If you are dealing with old sealant gone brittle and cracked and rain getting behind render or cladding at a joint, we can help.
In and around a place like Dunecht, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
There’s a 12-month guarantee on every job, large or small.

Your questions about external mastic in Dunecht
Do you cover smaller places like Dunecht?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Dunecht?
Yes. Our work covers the whole of Scotland, and Dunecht is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you use backing rod?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
Why it’s worth doing now in Dunecht
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What you get with us
- Any old sealant cut out fully, not covered over
- White, clear, grey or coloured to suit, where the product allows
- Over 20 years’ experience
- 12-month guarantee on every job

How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
The process
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Dunecht depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Outside joints around Dunecht
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Whether the job is in Dunecht itself or nearby, the right material for each joint matters as much as a neat finish.

What we’re called out for in Dunecht
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Look out for these signs:
- Sealant that has lost its bond to the brick or render
- Moss and dirt in joints with no sealant left
- Water getting into walls through failed joints
- Movement joints with cracked, split or missing sealant
Around Dunecht, as everywhere, external mastic is only as good as the preparation behind it.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
