External & façade joints in Armadale, West Lothian
Our applicators work in Armadale on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Act on the first splits you see
- Walk round the building once a year and look at the joints
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
How we handle external mastic in Armadale
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. We work on joints between brick and frames, brickwork movement joints and copings & trims, and common reasons people get in touch are brick movement joints where the sealant has split and movement joints filled with mortar instead of sealant.
Outside joints can only be sealed when they’re dry, so work in Armadale depends on the weather. Tell us how to reach each wall, gutter and roofline.
Whatever the size of the job, you get the same one-year guarantee in Armadale and across West Lothian.

Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before the bead.
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 movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
What you pay reflects the work, not guesswork. That is why we ask a few questions first.

Questions from Armadale
Do you cover Armadale for external mastic?
Yes, Armadale is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Will you come out to Armadale?
Yes. Armadale is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
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 do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then drop us a line at info@mrmastic.co.uk.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Honest limits
New sealant can’t fix everything, and we’ll tell you before any work starts. It won’t solve:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that’s more than a sealant joint can take
- Failed render or damaged cladding panels
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before booking.

How it works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

What external mastic looks like in Armadale
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.
If you look after a building such as Armadale Academy, larger buildings have long runs of movement joint that eventually need resealing.

When to call us in Armadale
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Any of these means the joints need attention:
- Water getting into walls through failed joints
- Joints with sealant missing in places
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
For landlords with property near Armadale station, outside joints that have cracked can let damp into a rental, so check them between lets.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
