About our external mastic in Maddiston
Ground-floor and low-level joints are straightforward to reach. 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. If you’re dealing with hard, crazed mastic that has stopped moving and gaps where render, brick and frames meet, we can help.
In and around a place like Maddiston, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
The work is covered for a year after we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Point out the joints to other trades
- Have failed joints looked at early
- Keep soil, plants and ivy away from the joints
- Make sure movement joints aren’t pointed over
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Walls and rooflines in Maddiston
Maddiston is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
If you let a flat or house near Polmont station, outside joints that have cracked can let damp into a rental, so check them between lets. Around Maddiston, as everywhere, external mastic is only as good as the preparation behind it.

Maddiston questions
Does the coastal weather in Maddiston affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Maddiston?
Yes. Maddiston is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
How long will you be here?
A typical job takes a few hours for a handful of joints, longer for a whole elevation. We will confirm how long when we quote.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
What happens on the day
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Outside jobs in Maddiston need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions

Advice
What the job involves on each surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out.
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Why it’s worth doing now in Maddiston
Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a place like Maddiston, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
