How we handle external mastic in Dunfermline
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. If you have weathered mastic that no longer stretches and plants rooting in failed movement joints, we can put it right, on copings & trims, concrete & block and render & cladding joints alike.
In a town like Dunfermline, plenty of homes have harled (roughcast) walls, and the joints where harling meets windows, doors and pipes need a sealant that grips and flexes. Gutters and fascias here take plenty of Scottish weather too.
We stand behind the work with a 12-month guarantee.

What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Private landlords in a town like Dunfermline must keep homes wind and watertight under the Repairing Standard. Replacing failed sealant early is simpler than dealing with a complaint.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

How the job changes by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and protects the render itself.
Common questions in Dunfermline
Does living near the coast affect external mastic in Dunfermline?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Is Dunfermline in your area for external mastic?
Yes, Dunfermline is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you work at height?
It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Will the new joint stand out?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
What does external mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Signs you need external mastic in Dunfermline
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
The problems people usually mention when they call include:
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
If you let a flat or house near Dunfermline City station, split movement joints are easy to miss on a rental until damp shows inside.

Dunfermline buildings and the weather
Dunfermline is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you look after a building such as Dunfermline High School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to St Leonard's Parish Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How the visit works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the building in most cases. For a job in Dunfermline, tell us where the work is, how to get in and where to park. Outside work depends on the weather, as sealant needs a dry surface.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Tell us if parking is tricky
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

Advice
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
- Render that is blown, hollow or coming away
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
