External & façade joints in Thomshill, Moray
Specialist external mastic for Thomshill: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
- Sealant that has lost its bond to the brick or render
DIY sealant or a professional job?
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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
About our external mastic in Thomshill
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you have rain getting behind render or cladding at a joint and cracked joints where brick meets render or frames, we can help, on brickwork movement joints, joints between brick and frames and copings & trims alike.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Questions from Thomshill
Can you do external mastic in Thomshill?
Yes. Our work covers the whole of Scotland, and Thomshill is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Will you come out to Thomshill?

What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk and let us know what needs doing and where.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Why do you put foam in the joint first?
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.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Walls and rooflines in Thomshill
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Homes close to Birnie Kirk include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. If you let a flat or house near Elgin station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Honest limits
We’ll always be straight with you, so here’s what sealant can’t fix:
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Brickwork movement joints
- Concrete & block
- Copings & trims
- Façade panels
- Render & cladding joints
- Joints between brick and frames
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Walk round the building once a year and look at the joints
- Wash walls gently around the sealant
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
The process
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. Around Thomshill, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at every joint and agree a colour to suit the wall.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky

Signs you need external mastic in Thomshill
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
The problems people generally mention when they call include:
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
Managing a site like Elgin High School? Then its movement joints, gutters and trims need looking after like any other building’s.
