How we handle external mastic in Coalsnaughton
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you have movement joints filled with mortar instead of sealant and water getting into walls through failed joints, we can help.
External sealant needs dry surfaces, so outdoor work around Coalsnaughton is planned around the weather. Tell us how to reach each wall, gutter and roofline.
Every job is covered by a 12-month guarantee, wherever you are in Clackmannanshire.

Aftercare tips
So the new joints stay in good condition:
- Check the sealant is paintable before painting near it
- Keep water from gutters off the wall
- Show decorators and builders where the movement joints are
- Check external joints each spring
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
What external mastic looks like in Coalsnaughton
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Rented homes near Alloa station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

What else we do in Coalsnaughton
Do you need external mastic in Coalsnaughton?
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.
The most common problems we see are:
- Failed sealant between panels on a façade
- Weathered mastic that no longer stretches
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
In and around Coalsnaughton, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Your questions about external mastic in Coalsnaughton
Will you come out to Coalsnaughton?
Yes. Coalsnaughton is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Coalsnaughton?
Yes, Coalsnaughton is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
What sealant work can’t fix
Before you book, it’s worth knowing the limits:
- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
- Rising or penetrating damp from elsewhere in the wall
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
