- Failed sealant between panels on a façade
External mastic for homes and businesses in Auchinloch
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 joints between brick and frames, brickwork movement joints and concrete & block, and the jobs we see most are leaking joints around cladding and façade panels and plants rooting in failed movement joints.
Outside joints can only be sealed when they’re dry, so work in Auchinloch depends on the weather. Tell us how to reach each wall, gutter and roofline.
You are covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

External mastic in Auchinloch: local notes
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. Historic houses like Provand's Lordship (about 4.8 miles south-west) are a reminder that the area around Auchinloch has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Lenzie station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Lenzie Old Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Auchinloch is about 2 miles south of Kirkintilloch, in East Dunbartonshire. Jobs in Auchinloch get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. 23 places in East Dunbartonshire are on our list.

Your questions about external mastic in Auchinloch
Do you cover smaller places like Auchinloch?
Yes, Auchinloch is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Lenzie station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch. If it has already been filled, we can usually cut it out and reseal it.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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.
How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.
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.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep high-pressure jets off the joints
- Have failed joints looked at early
- Make sure movement joints aren’t pointed over
- Point out the joints to other trades
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Outdoor work around Auchinloch depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints

Common problems we fix in Auchinloch
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.
Look out for these signs:
- Leaking joints around cladding and façade panels
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Joints where the bead has come unstuck
If you look after a building such as Chryston High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include
- Who does the work, and how experienced they are
- What product goes in the joint
- How the colour is chosen
- What happens if they find a problem under the old sealant
