Dunshalt External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Dunshalt and across Fife. Fully insured, ARBOMaster approved and guaranteed for a year.
- Joints where the bead has come unstuck
- Water getting into walls through failed joints
- Cracked joints where brick meets render or frames
How we handle external mastic in Dunshalt
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it. Typical jobs include movement joints with cracked, split or missing sealant and panel joints letting water in, across copings & trims, joints between brick and frames and concrete & block.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Keep high-pressure jets off the joints
- Keep water from gutters off the wall
- Check the sealant is paintable before painting near it
- Check external joints each spring
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
When it isn’t the sealant
We won’t take on work that will not last, so these are the limits:
- Cracking across the wall rather than at a joint
- Movement that is more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.

Surface by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out.
What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. Somewhere like Dunshalt may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Keep children and pets away from the work area
- Let us know about parking restrictions
- Tell us about any water getting in

Advice
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Your questions about external mastic in Dunshalt
Do you cover Dunshalt for external mastic?

Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Walls and rooflines in Dunshalt
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For an older house near a landmark such as Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Ladybank station, outside joints that have cracked can let damp into a rental, so check them between lets.
