External mastic in Lightburn
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. If you have gaps where render, brick and frames meet and panel joints letting water in, we can put it right, whatever the surface.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. For a building in Lightburn, access is planned first, and shared parts may need the other owners to agree.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Lightburn questions
How is work on the outside of a tenement in Lightburn normally 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 don’t, and we can quote for the factor or the owners directly.
Is Lightburn in your area for external mastic?
Yes, Lightburn is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
How long does external mastic take?
A typical job takes anything from a few hours to several days, depending on the building, including preparation and clearing up. We will confirm how long when we quote.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Why do you put foam in the joint first?
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.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Where is Mr Mastic based?
We work from Crawley. We cover Lightburn and the rest of Glasgow, along with the rest of our area.
Walls and rooflines in Lightburn
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Your title deeds say which parts are shared.

- The problem you’ve noticed

Signs you need external mastic in Lightburn
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Keep an eye out for these signs:
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
- Movement joints with cracked, split or missing sealant
If you let a flat or house near Carntyne station, outside joints that have cracked can let damp into a rental, so check them between lets.
What your quote should include
- How the joint is cleaned and prepared
- Whether they’re fully insured
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
How to look after the new joints
After the cure time, these simple habits help:
- Avoid pressure-washing directly into sealant joints
- Leave the joints unpainted unless we have said otherwise
- Walk round the building once a year and look at the joints
- Point out the joints to other trades
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.

How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one.
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.
What sealant work can’t fix
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.

The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on the building.

- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Mention any leaks or damp you’ve noticed

- Mention any sign-in or site rules at work premises

Why it’s worth doing now in Lightburn
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Lightburn, damp can travel a long way before it shows.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
