External mastic in Pathhead
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 where a rigid filler would soon crack. Common call-outs are for brick movement joints where the sealant has split and water getting into walls through failed joints, on façade panels, brickwork movement joints and concrete & block.
Outside joints can only be sealed when they’re dry, so work in Pathhead depends on the weather. Let us know about access to every wall and roofline.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Around Pathhead, water from a failed joint in an older stone home can soak into timber and plaster.

How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. Around Pathhead, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

How long before the joint can be used?
Cure times vary by product. Before we leave, we will tell you the cure time.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
How to look after the new joints
To keep the joints looking good and working properly:
- Have failed joints looked at early
- Check external joints each spring
- Ask before painting over external sealant
- Never let anyone fill a movement joint with mortar
Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Outside joints around Pathhead
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.

The problems people normally mention when they call include:
- Failed seals between different materials
- Joints with sealant missing in places
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
For landlords with property near Gorebridge station, split movement joints are easy to miss on a rental until damp shows inside.
