External mastic in Stoneywood
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Typical jobs include cracked joints where brick meets render or frames and old sealant gone brittle and cracked, on copings & trims, joints between brick and frames and concrete & block.
In and around a place like Stoneywood, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.

Outside joints around Stoneywood
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In the older streets around Church Of Scotland, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Bucksburn Academy? Then larger buildings have long runs of movement joint that eventually need resealing.

Leave it or put it right?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. In an older home around Stoneywood, damp from a failed joint can get into timber and plaster.

The process
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. Outdoor work around Stoneywood 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.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Mention any tricky access

Advice
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.

What else we do in Stoneywood
When to call us in Stoneywood
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Keep an eye out for these signs:
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
Rented homes near Dyce station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before you book

Stoneywood: your questions answered

Where are you based?

What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
