Our external mastic service in South Lanarkshire

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. Typical jobs include panel joints letting water in and old sealant gone brittle and cracked, on façade panels, brickwork movement joints and render & cladding joints.

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building and we leave things clean and tidy.

We look at every joint and agree a colour to suit the wall.
We take out the old sealant until the faces are sound.
Backing rod goes in so the sealant can stretch between the two faces.
We prime the faces where required.
We gun in low-modulus sealant and tool it neatly.

Pricing in South Lanarkshire

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

External mastic across South Lanarkshire: local notes

From East Kilbride, Hamilton and Cambuslang to its smaller places, buildings across South Lanarkshire have walls, gutters and rooflines of every age. Each needs a sealant that can move, laid at the right depth.

Our work covers the whole of Scotland, South Lanarkshire included. Longer journeys are planned in advance, and outdoor work around the weather.

East Kilbride: Letting a property close to East Kilbride station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Duncanrig Secondary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Leave it or put it right?

A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it.

What sealant work can’t fix

We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:

Structural movement, which needs a surveyor or engineer
Cracked brickwork or render that needs a builder or plasterer
Failed render or damaged cladding panels

Should I try it myself first?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How the job changes by surface

Render joints

Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.

Brickwork movement joints

People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly where it can be done safely.

What we are called out for in South Lanarkshire

A lot of failed joints come down to preparation: 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.

These are the problems we’re asked about most:

Sealant pulling away from one side of the joint
Moss and dirt in joints with no sealant left
Joints with sealant missing in places
Old sealant gone brittle and cracked

Your questions about external mastic in South Lanarkshire

When will the joints need doing again?

There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.

Do you have insurance?

Yes. We’re fully insured, and we can confirm the details when we quote.

Do you use backing rod?

Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

How long before the joint can be used?

Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.

Can you match the colour of my brickwork?

We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins.

How much does external mastic cost in South Lanarkshire?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
