External & façade joints in Woodside, Glasgow
Our applicators work in Woodside on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
- Plants rooting in failed movement joints
External mastic in Woodside, done properly
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. Typical jobs include movement joints with cracked, split or missing sealant and rigid filler in a joint that should flex, across brickwork movement joints, render & cladding joints and façade panels.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. In Woodside, those joints dry out over time and let water in behind the render or cladding.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Woodside questions
Can you help a landlord with a rental near Charing Cross (Glasgow) station?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Who arranges sealant work on the shared parts of a tenement in Woodside?
It normally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
How do you reach high-level joints?
That depends on the building and the joints. Where joints can be reached safely, we’ll do them. Give us some details and we’ll confirm the access.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
When it isn’t the sealant
It helps to know what we cannot do too:
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.
What we seal
- Joints between brick and frames
- Façade panels
- Copings & trims
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
Walls and rooflines in Woodside
The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. Glasgow’s tenements are largely red and blond sandstone, and porous sandstone needs a sealant that won’t mark it.
For an older house near a landmark such as St Vincent Street Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like College of Piping? Then larger buildings have long runs of movement joint that eventually need resealing.

Why it’s worth doing now in Woodside
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. In a tenement flat in Woodside, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.

- How easy the joints are to reach

What we’re called out for in Woodside
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
People normally contact us after spotting something like this:
- Weathered mastic that no longer stretches
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
If you let a flat or house near Charing Cross (Glasgow) station, outside joints that have cracked can let damp into a rental, so check them between lets.

How to look after the new joints
Looking after new joints is easy:
- Fix overflowing gutters above sealed joints
- Tell anyone working on the walls about the movement joints
- Keep soil, plants and ivy away from the joints
- Never let anyone fill a movement joint with mortar
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
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. All told, the work takes a few hours to a few days, depending on the length of joint and the access. For a tenement in Woodside, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
