About our external mastic in Ellon
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on render & cladding joints, façade panels and brickwork movement joints, and people most often call us about sealant that has lost its bond to the brick or render and water getting into walls through failed joints.
In and around a place like Ellon, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
All our work is covered by a one-year guarantee.

Questions from Ellon
Do you cover Ellon for external mastic?
Yes, Ellon is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Is there a guarantee on external mastic in Ellon?
All our work, in Ellon and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Should I try it myself first?
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, and the work is guaranteed for a year.
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.
Honest limits
To be straight with you, some problems need a different trade:
- Cracked brickwork or render that needs a builder or plasterer
- Movement that’s more than a sealant joint can take
- Walls that need new movement joints cut into them
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Other services in Ellon
Outside joints around Ellon
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
If you look after a building such as Ellon Academy, its movement joints, gutters and trims need looking after like any other building’s.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get split or bare joints resealed while the damage is small
- Keep movement joints as flexible joints, not mortar
- Don’t let climbing plants root in the sealant
- Tell anyone working on the walls about the movement joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Common problems we fix in Ellon
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 rips as the joint opens.
Any of these means the joints need attention:
- Failed seals between different materials
- Rain getting behind render or cladding at a joint
- Rigid filler in a joint that should flex
- Failed sealant between panels on a façade
In and around Ellon, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

The process
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Ellon depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
