Bridge of Cally External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Bridge of Cally and across Perth and Kinross. Fully insured, ARBOMaster approved and guaranteed for a year.
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
- Damp patches traced to an open external joint
How we handle external mastic in Bridge of Cally
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. If you’re dealing with gaps where render, brick and frames meet and movement joints with cracked, split or missing sealant, we can help, on copings & trims, render & cladding joints and concrete & block alike.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
Each job carries a 12-month guarantee, whatever its size.

When something else is needed
A few problems are outside what sealant work can do:
- Rising or penetrating damp from elsewhere in the wall
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer

Signs you need external mastic in Bridge of Cally
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Common reasons people contact us are:
- Movement joints filled with mortar instead of sealant
- Water getting into walls through failed joints
- Weathered mastic that no longer stretches
- Plants rooting in failed movement joints
In the older streets around Netherton Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Outside joints around Bridge of Cally
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In and around Bridge of Cally, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

How the job changes by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Why act early in Bridge of Cally
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. 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.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we have said otherwise
- Do not let climbing plants root in the sealant
- Keep high-pressure jets off the joints
Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
What happens on the day
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work usually takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Bridge of Cally may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Questions from Bridge of Cally
Is external mastic in Bridge of Cally guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Bridge of Cally?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.
How much does external mastic cost in Bridge of Cally?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Do you work for letting agents?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
