Surface by surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
External mastic in Earlston, done properly
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We work on joints between brick and frames, copings & trims and brickwork movement joints, and the jobs we see most are sealant that has lost its bond to the brick or render and gaps where render, brick and frames meet.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why it’s worth doing now in Earlston
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
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 make a difference.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Earlston depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Let us know about parking restrictions
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Do you need external mastic in Earlston?
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The problems people usually mention when they call include:
- Plants rooting in failed movement joints
- Cracked joints where brick meets render or frames
- Hard, crazed mastic that has stopped moving
- Joints where the bead has come unstuck
Schools such as Earlston High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before you book

What external mastic looks like in Earlston
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For landlords with property near Tweedbank station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Earlston Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Never let anyone fill a movement joint with mortar
- Keep high-pressure jets off the joints
- Keep soil, plants and ivy away from the joints
- Have failed joints looked at early
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
