External mastic in Braidwood
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. We’re often asked to deal with weathered mastic that no longer stretches and movement joints filled with mortar instead of sealant, across concrete & block, render & cladding joints and brickwork movement joints.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Aftercare tips
After the cure time, these simple habits help:
- Have failed joints looked at early
- Check the sealant is paintable before painting near it
- Keep soil, plants and ivy away from the joints
- Check external joints each spring
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
Outside joints around Braidwood
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.
Rented homes near Carluke station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Schools such as Carluke High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How it works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules

What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. In an older home around Braidwood, damp from a failed joint can get into timber and plaster.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

FAQs for Braidwood
Do you cover smaller places like Braidwood?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Carluke station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
How long does the job take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the building. We will give you a better idea when we quote.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
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.
