DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
About our external mastic in Auchinraith
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on copings & trims, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are sealant pulling away from one side of the joint and movement joints filled with mortar instead of sealant.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
Big or small, you get the same one-year guarantee in Auchinraith and across South Lanarkshire.

Work for landlords, hotels and businesses
For anyone letting property in or around Auchinraith, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.

How the visit works
At the end, we look at the finished work together. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. Outdoor work around Auchinraith depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
Getting ready for the visit
- Mention any tricky access
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

What external mastic looks like in Auchinraith
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For landlords with property near Blantyre station, split movement joints are easy to miss on a rental until damp shows inside.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Look over the joints every year, ideally after winter
- Deal with leaking gutters that soak the joints below
- Point out the joints to other trades
- Have failed joints looked at early
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
What we’re called out for in Auchinraith
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 new sealant then lets go long before it should.
Most people get in touch when they notice something like this:
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Panel joints letting water in
- Movement joints filled with mortar instead of sealant
If you look after a building such as John Ogilvie High School, larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- When the joint can take water or movement
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
