How the job changes by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.
External mastic in Laighstonehall, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We work on copings & trims, render & cladding joints and concrete & block, and the jobs we see most are leaking joints around cladding and façade panels and brick movement joints where the sealant has split.
In and around a place like Laighstonehall, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work

Questions from Laighstonehall
Can you do external mastic in Laighstonehall?

Can you help a landlord with a rental near Hamilton West station?

What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
How often do external joints need resealing?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Are you insured?
Yes. Mr Mastic is fully insured.
Signs you need external mastic in Laighstonehall
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
Look out for any of the following:
- Gaps where render, brick and frames meet
- Weathered mastic that no longer stretches
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake
For landlords with property near Hamilton West station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What else we do in Laighstonehall
How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. Outside jobs in Laighstonehall need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Mention any tricky access
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Laighstonehall buildings and the weather
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 failed outside joints work against that.
Managing a site like Earnock High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Cambusnethan House, about 4.8 miles east, is one of the historic houses in the wider area around Laighstonehall.

How to look after the new joints
Aftercare is simple:
- Clear growth from the base of walls and joints
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
