External & façade joints in Cambuslang, South Lanarkshire
Our applicators work in Cambuslang on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

- Brick movement joints where the sealant has split
- Plants rooting in failed movement joints
Why act early in Cambuslang
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. If you live in a flat in Cambuslang, failed sealant can send water to the neighbours below, which turns a small job into a bigger one.
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Why us?
- A 12-month guarantee on all work
- An ARBOMaster approved applicator
- Anti-fungal sanitary silicone in wet areas
- Neat joints and a tidy finish

How we handle external mastic in Cambuslang
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. Typical jobs include rain getting behind render or cladding at a joint and plants rooting in failed movement joints, on joints between brick and frames, render & cladding joints and brickwork movement joints.
Scottish weather is hard on outside joints, and a town like Cambuslang gets its share of wind and rain. Gaps in gutter joints, fascias and wall joints are where damp starts.
The work is covered for a year after we finish. If anything is not right with it, email us at info@mrmastic.co.uk.

Common problems we fix in Cambuslang
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Most people get in touch after spotting something like this:
- Sealant pulling away from one side of the joint
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
Historic houses such as Provand's Lordship, about 4.7 miles north-west, show how far back building around Cambuslang goes.

Cambuslang: your questions answered
Can you do external mastic in Cambuslang?
Yes, Cambuslang is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
I let a flat near Newton station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
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.
How long should I leave it?
It depends on the product. We tell you how long to leave it before we go.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How to look after the new joints
After the cure time, these simple habits help:
- Keep movement joints as flexible joints, not mortar
- Keep soil, plants and ivy away from the joints
- Wash walls gently around the sealant
- Leave the joints unpainted unless we’ve said otherwise
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.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Landlords, agents and businesses in Cambuslang
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
What we do, step by step
On the day, we look over the joints with you first. Surfaces next to the work are protected before work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Parking around Cambuslang is rarely difficult, though older streets in the centre can be tight. If you are in a flat with a shared stair or a door entry system, let us know when you book.
- 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.

Advice
Outside joints around Cambuslang
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Carmyle Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Newton station? Then split movement joints are easy to miss on a rental until damp shows inside.
