Daldowie External Mastic
We cover Daldowie for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
External mastic in Daldowie
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you have brick movement joints where the sealant has split and failed sealant between panels on a façade, we can put it right.
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.
Big or small, it’s backed by our one-year guarantee.

Your questions about external mastic in Daldowie
Do you cover smaller places like Daldowie?
Yes, Daldowie is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do external mastic in Daldowie?
Yes, Daldowie is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
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.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Act on the first splits you see
- Fix overflowing gutters above sealed joints
- Leave the joints unpainted unless we’ve said otherwise
- Point out the joints to other trades
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Signs you need external mastic in Daldowie
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint.
Any of these means the joints need attention:
- Failed seals between different materials
- Panel joints letting water in
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
For landlords with property near Baillieston station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Who turns up on the day
- When the joint can take water or movement
- Which colour the sealant will be
- What insurance they hold
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
What external mastic looks like in Daldowie
The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Managing a site like Uddingston Grammar School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What else we do in Daldowie
Why act early in Daldowie
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
