External & façade joints in Hamiltonhill, Glasgow
We cover Hamiltonhill for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
Signs you need external mastic in Hamiltonhill
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Any of these means the joints need attention:
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
Managing a site like St Aloysius' College? Then larger buildings have long runs of movement joint that eventually need resealing.

How we handle external mastic in Hamiltonhill
On houses, flats and commercial buildings across Hamiltonhill, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have damp patches traced to an open external joint and panel joints letting water in, we can put it right.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. In Hamiltonhill, those joints dry out over time and let water in behind the render or cladding.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Can I do it myself?
If you do try it yourself, take your time over the 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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Inside a flat in Hamiltonhill, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Tell us about any water getting in

Related advice
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Get split or bare joints resealed while the damage is small
- Leave the joints unpainted unless we have said otherwise
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
What the job involves on each surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Questions from Hamiltonhill
How is work on the outside of a tenement in Hamiltonhill usually arranged?
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, and we can quote for the factor or the owners directly.
Can you help a landlord with a rental near Possilpark & Parkhouse 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 send you a clear quote.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

What we can’t put right
To be straight with you, some problems need a different trade:

- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracking across the wall rather than at a joint
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

What external mastic looks like in Hamiltonhill

In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
