About our external mastic in Bridge of Allan
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. Typical jobs include rigid filler in a joint that should flex and joints where the bead has come unstuck, on façade panels, brickwork movement joints and copings & trims.
In and around a place like Bridge of Allan, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
There’s a 12-month guarantee on every job, large or small.

Signs you need external mastic in Bridge of Allan
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Any of these means the joints need attention:
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
If you let a flat or house near Bridge of Allan station, split movement joints are easy to miss on a rental until damp shows inside.

Walls and rooflines in Bridge of Allan
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 sound outside sealant is part of that.
Homes close to St Saviour's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Wallace High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Call for a quick quote. What matters most is:
- The product the joint needs

- If it’s domestic, commercial or a hotel

Keeping the joints in good condition
So the new joints stay in good condition:
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Keep soil, plants and ivy away from the joints
- Make sure movement joints aren’t pointed over
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
Should I try it myself first?
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 biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Bridge of Allan: your questions answered
Can you help a landlord with a rental near Bridge of Allan station?
Yes, we work for landlords and agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Bridge of Allan?
Yes, Bridge of Allan is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint
- Render that is blown, hollow or coming away
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Render & cladding joints
- Brickwork movement joints
- Joints between brick and frames
- Copings & trims
- Façade panels
- Concrete & block
