Flemington questions
Can you help a landlord with a rental near Newton station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do you cover Flemington for external mastic?
Yes. Our work covers the whole of Scotland, and Flemington is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we’ll tell you how long to expect.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render. Exterior sealants come in a good range of colours.
External mastic for homes and businesses in Flemington
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. Typical jobs include plants rooting in failed movement joints and leaking joints around cladding and façade panels, across brickwork movement joints, copings & trims and concrete & block.
Outside joints can only be sealed when they’re dry, so work in Flemington depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Do you need external mastic in Flemington?
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
People normally contact us when they notice one of these:
- Gaps where render, brick and frames meet
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
Letting a property close to Newton station? Then split movement joints are easy to miss on a rental until damp shows inside.

Outside joints around Flemington
Flemington is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Schools such as Rutherglen High School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.
For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Leave the joints unpainted unless we have said otherwise
- Wash walls gently around the sealant
- Clear growth from the base of walls and joints
- Walk round the building once a year and look at the joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What happens on the day
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. Outdoor work around Flemington depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- 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.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
