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

- Cracked joints where brick meets render or frames
- Panel joints letting water in
What we’re called out for in Greenhills
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Look out for these signs:
- Old sealant gone brittle and cracked
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
For landlords with property near East Kilbride station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic for homes and businesses in Greenhills
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. Typical jobs include water getting into walls through failed joints and moss and dirt in joints with no sealant left, on concrete & block, render & cladding joints and brickwork movement joints.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Work for landlords, hotels and businesses
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.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours for a handful of joints, longer for a whole elevation. For a place like Greenhills, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property

Advice
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Outside joints around Greenhills
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. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
If you look after a building such as Duncanrig Secondary School, its movement joints, gutters and trims need looking after like any other building’s.

When it isn’t the sealant
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints

Common questions in Greenhills
Can you help a landlord with a rental near East Kilbride station?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Do you cover smaller places like Greenhills?
Yes. Greenhills is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move, and it should be sealed with a flexible sealant.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new sealant bonds properly.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can you reach joints on upper floors?
It depends on the building. Send us photos and a rough idea of the height and we will confirm how they can be reached safely.
Why it’s worth doing now in Greenhills
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. In an older home around Greenhills, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
