About our external mastic in Greenigoe
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on joints between brick and frames, façade panels and copings & trims, and the jobs we see most are sealant pulling away from one side of the joint and rigid filler in a joint that should flex.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
The work is covered for a year after we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Common problems we fix in Greenigoe
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
The problems people usually mention when they call are:
- Failed seals between different materials
- Joints pointed up with cement by mistake
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
Around Greenigoe, as everywhere, external mastic is only as good as the preparation behind it.

Walls and rooflines in Greenigoe
Greenigoe is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For jobs in and around Greenigoe, choosing the right material for each joint is as important as a tidy finish.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
FAQs for Greenigoe
Is Greenigoe in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Greenigoe is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Is external mastic in a coastal place like Greenigoe any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
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.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. Outside jobs in Greenigoe need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First, the joints are inspected and the access agreed.
- 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.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Clear items away from the joints we’re working on
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed

How the job changes by surface
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Looking after it afterwards
So the new joints stay in good condition:
- Never let anyone fill a movement joint with mortar
- Have failed joints looked at early
- Leave the joints unpainted unless we’ve said otherwise
- Point out the joints to other trades
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
Why act early in Greenigoe
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Around Greenigoe, water from a failed joint in an older stone home can soak into timber and plaster.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.
