Glensburgh External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Glensburgh and across Falkirk. Fully insured, ARBOMaster approved and guaranteed for a year.
- Panel joints letting water in
- Joints with sealant missing in places
- Damp patches traced to an open external joint
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Damp that is not coming from the joint
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
Joints and surfaces we work on
- Brickwork movement joints
- Concrete & block
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
- Façade panels
External mastic in Glensburgh, done properly
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we will confirm what access is needed. We work on façade panels, concrete & block and joints between brick and frames, and the jobs we see most are movement joints filled with mortar instead of sealant and sealant that has lost its bond to the brick or render.
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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on the building. Outside jobs in Glensburgh need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Common questions in Glensburgh
Do you work for landlords with property near Falkirk Grahamston 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 will give you a clear quote.
Do you cover smaller places like Glensburgh?
Yes, Glensburgh is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is normally a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.
Are you insured?
Yes. Full insurance covers our work.
How much does external mastic cost in Glensburgh?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Glensburgh buildings and the weather
Glensburgh is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For landlords with property near Falkirk Grahamston station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

When to call us in Glensburgh
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Keep an eye out for these signs:
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
Schools such as Graeme High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. In an older home around Glensburgh, damp from a failed joint can get into timber and plaster.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Have failed joints looked at early
- Fix overflowing gutters above sealed joints
- Leave the joints unpainted unless we’ve said otherwise
- Do not let climbing plants root in the sealant
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
