DIY sealant or a professional job?
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. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
About our external mastic in Springboig
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. Common call-outs are for rigid filler in a joint that should flex and damp patches traced to an open external joint, across copings & trims, brickwork movement joints and render & cladding joints.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. In Springboig, work on shared parts of a tenement is generally agreed between owners, often with a factor arranging it.
Our work is backed for twelve months, in Springboig and everywhere else we cover.

Keeping the joints in good condition
Looking after new joints is easy:
- Look over the joints every year, ideally after winter
- Keep high-pressure jets off the joints
- Have failed joints looked at early
- Point out the joints to other trades
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
What external mastic looks like in Springboig
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. With historic houses such as Provand's Lordship (about 3.1 miles west) nearby, there’s older building stock in the area around Springboig as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around St Serf's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as St Andrew's Secondary School, larger buildings have long runs of movement joint that eventually need resealing.

Questions from Springboig
Can you do external mastic in Springboig?
Yes. We work across all of Scotland, and Springboig is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
How is work on the outside of a tenement in Springboig normally arranged?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Springboig.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
How long does external mastic take?
It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
Do you need external mastic in Springboig?
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
- Panel joints letting water in
For landlords with property near Shettleston station, split movement joints are easy to miss on a rental until damp shows inside.
Before you book anyone
- When the joint can take water or movement
- Whether the sealant suits the joint
- What preparation is included
- Whether they seal over old material or remove it
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. In a tenement flat in Springboig, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before we start.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a handful of joints, longer for a whole elevation. Inside a flat in Springboig, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- 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.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

How the job changes by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
What affects the cost of external mastic
Your quote is based on your job. We look at:
- Access and height
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Mould in or behind the old joints
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know
To make quoting easier, please include:
- Any previous sealing or DIY work
- The address or postcode of the job
- The rough size of the job
- What’s wrong with the joints now
