External Mastic in Birkenshaw
We cover Birkenshaw for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Deal with leaking gutters that soak the joints below
- Point out the joints to other trades
- Clear growth from the base of walls and joints
- Check the sealant is paintable before painting near it
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
External mastic for homes and businesses in Birkenshaw
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We work on brickwork movement joints, concrete & block and render & cladding joints, and common reasons people get in touch are gaps where render, brick and frames meet and movement joints with cracked, split or missing sealant.
Outside joints can only be sealed when they’re dry, so work in Birkenshaw depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
All of our work is guaranteed for twelve months, in Birkenshaw and everywhere else we cover.

Birkenshaw questions
Can you help a landlord with a rental near Uddingston station?
Yes, we work for letting agents and landlords. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Can you do external mastic in Birkenshaw?
Yes, Birkenshaw is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What does external mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Leave it or put it right?
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Any old sealant cut out fully, not covered over
- Approved under the ARBOMaster scheme
- Homes, businesses and hotels
- Arbo and Everbuild products

When to call us in Birkenshaw
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Any of these means the joints need attention:
- Joints pointed up with cement by mistake
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
If you look after a building such as Uddingston Grammar School, its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- How long the guarantee is
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- Which colour the sealant will be
Outside joints around Birkenshaw
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.
Letting a property close to Uddingston station? Then split movement joints are easy to miss on a rental until damp shows inside.

DIY versus a professional finish
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What we do, step by step
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Birkenshaw depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
