External & façade joints in Cowie, Stirling
We cover Cowie for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
What the job involves on each surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
External mastic for homes and businesses in Cowie
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have water getting into walls through failed joints and sealant that has lost its bond to the brick or render, we can put it right, on concrete & block, joints between brick and frames and render & cladding joints alike.
Outside joints can only be sealed when they’re dry, so work in Cowie depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
There’s a 12-month guarantee on every job, whatever its size.

What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before work begins.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, 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.
What external mastic looks like in Cowie
Cowie is close to 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. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Around Cowie, as everywhere, external mastic is only as good as the preparation behind it. For landlords with property near Stirling station, outside joints that have cracked can let damp into a rental, so check them between lets.
Cowie is about 4 miles south-east of Stirling, in Stirling. Across the FK7 area, we cover external mastic for homes and businesses. Our Stirling coverage runs to 55 places, and Cowie is one of them. There’s also a page for Glasgow, roughly 22 miles from Cowie.
All of FK7 is covered for external mastic. We cover properties on Main Street, Station Road and Mount Oliphant and the roads around them.

When it is not the sealant
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
- Subsidence or other structural problems
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.

What affects the cost of external mastic
Your quote is based on your job. We look at:
- The amount of work
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- When we can work, for business premises
What it costs depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Helping us quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- The type of property
- How we’d reach the joints
If you are in Cowie and need external mastic, drop us a line at info@mrmastic.co.uk. Tell us what the problem is and where, and you will get a clear quote before any work starts.
Looking after it afterwards
So the new joints stay in good condition:
- Ask before painting over external sealant
- Deal with leaking gutters that soak the joints below
- Point out the joints to other trades
- Keep high-pressure jets off the joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. Around Cowie, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

Advice
Cowie: your questions answered
Can you help a landlord with a rental near Stirling station?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Is Cowie within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
