External mastic for homes and businesses in Stenton
For buildings in Stenton, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you have weeds or debris growing in open joints and panel joints letting water in, we can help, whatever the surface.
In and around a place like Stenton, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
- Walls that need new movement joints cut into them
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.
Joints and surfaces we work on
- Render & cladding joints
- Copings & trims
- Joints between brick and frames
- Façade panels
- Brickwork movement joints
- Concrete & block
Surface by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
What external mastic looks like in Stenton
Stenton is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In the older streets around Stenton Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What we’re called out for in Stenton
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Keep an eye out for these signs:
- Hard, crazed mastic that has stopped moving
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
Letting a property close to East Linton station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before you book
- Is the old sealant removed completely?
- How hidden problems are handled
- How the colour is chosen
- Whether VAT is included
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Look over the joints every year, ideally after winter
- Point out the joints to other trades
- Avoid pressure-washing directly into sealant joints
- Deal with leaking gutters that soak the joints below
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Stenton questions
Is external mastic in a coastal place like Stenton any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near East Linton station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Can you reach joints on upper floors?
It depends on the building. Send us photos and a rough idea of the height, and we’ll confirm what access is needed.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
How it works
When we arrive, we start by going over the job with you, so there are no surprises. 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. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
