About our external mastic in Causewayhead
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. If you have gaps where render, brick and frames meet and leaking joints around cladding and façade panels, we can put it right, whatever the surface.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
There’s a 12-month guarantee on every job, whatever its size.

Why act early in Causewayhead
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Around Causewayhead, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

Causewayhead: your questions answered
I let a flat near Stirling station. Can you help?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Do you cover Causewayhead for external mastic?
Yes, Causewayhead is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Do you have insurance?
Yes. We are fully insured.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
How often do external joints need resealing?
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 reseal when it splits.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Common problems we fix in Causewayhead
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
People usually contact us when they notice one of these:
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
If you look after a building such as Wallace High School, larger buildings have long runs of movement joint that eventually need resealing.

The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes a few hours to a few days, depending on the length of joint and the access. For a place like Causewayhead, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.

Outside joints around Causewayhead
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. 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.
Rented homes near Stirling station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the job changes by surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep water from gutters off the wall
- Do not let climbing plants root in the sealant
- Point out the joints to other trades
- Check external joints each spring
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
