- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
- Failed render or damaged cladding panels

External mastic for homes and businesses in Maxton
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. We work on brickwork movement joints, copings & trims and concrete & block, and people most often call us about weeds or debris growing in open joints and leaking joints around cladding and façade panels.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
Whatever the size of the job, you get the same 12-month guarantee.

When to call us in Maxton
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
These are the problems we are asked about most:
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
Around Maxton, as everywhere, external mastic is only as good as the preparation behind it.

Maxton questions
Can you do external mastic in Maxton?
Yes. Our work covers the whole of Scotland, and Maxton is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Will you come out to Maxton?
Yes. Maxton is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
How much does external mastic cost in Maxton?
Size, access and the old material all affect the cost. Ask us for a quote.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

How the job changes by surface
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before sealing.
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Show decorators and builders where the movement joints are
- 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
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What external mastic looks like in Maxton
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you live in an older home near Maxton Kirk, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. Outside jobs in Maxton need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- 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.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Clear the area around the work
