About our external mastic in Countesswells
For buildings in Countesswells, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on render & cladding joints, brickwork movement joints and concrete & block, and common reasons people get in touch are hard, crazed mastic that has stopped moving and brick movement joints where the sealant has split.
In and around a place like Countesswells, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
Big or small, it’s backed by our 12-month guarantee in Countesswells and across Aberdeen.

For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
When to call us in Countesswells
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall.
People usually contact us after spotting one of these:
- Moss and dirt in joints with no sealant left
- Weathered mastic that no longer stretches
- Sealant that has lost its bond to the brick or render
- Movement joints filled with mortar instead of sealant

FAQs for Countesswells
I let a flat near Aberdeen station. Can you help?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Do you cover Countesswells for external mastic?
Yes, Countesswells is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
What’s an expansion joint in brickwork?
Walls move with heat, cold and moisture, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before any work starts.
Looking after it afterwards
So the new joints stay in good condition:
- Check the sealant is paintable before painting near it
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
- Get split or bare joints resealed while the damage is small
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.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. Around Countesswells, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- 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.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand.

What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.

External mastic in Countesswells: local notes
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Church Of Scotland, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Hazlehead Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
