How we handle external mastic in Swinton
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on copings & trims, concrete & block and joints between brick and frames, and the jobs we see most are sealant that has lost its bond to the brick or render and leaking joints around cladding and façade panels.
External sealant needs dry surfaces, so outdoor work around Swinton is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
Looking after new joints is easy:
- Keep movement joints as flexible joints, not mortar
- Tell anyone working on the walls about the movement joints
- Check the sealant is paintable before painting near it
- Act on the first splits you see
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.

Swinton: your questions answered
Is Swinton in your area for external mastic?
Yes, Swinton is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Will you come out to Swinton?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, wherever you are.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.
Honest limits
New sealant can’t fix everything, and we will tell you before we start. It won’t solve:
- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Advice
Walls and rooflines in Swinton
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Around Swinton, as everywhere, external mastic is only as good as the preparation behind it. For jobs in and around Swinton, choosing the right material for each joint is as important as a tidy finish.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the 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.
Why it’s worth doing now in Swinton
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last. In an older home around Swinton, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
