External mastic in Stanley, done properly
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what access is needed. We work on copings & trims, façade panels and concrete & block, and people most often call us about weathered mastic that no longer stretches and sealant pulling away from one side of the joint.
External sealant needs dry surfaces, so outdoor work around Stanley is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
You’re covered for a year from the day we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Signs you need external mastic in Stanley
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Any of these means the joints need attention:
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
- Rigid filler in a joint that should flex
- Sealant pulling away from one side of the joint
Around Stanley, as everywhere, external mastic is only as good as the preparation behind it.
What your quote should include
- Who turns up on the day
- Whether they’re fully insured
- Whether they seal over old material or remove it
- What the quote includes, VAT included or not
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Keep soil, plants and ivy away from the joints
- Point out the joints to other trades
- Keep high-pressure jets off the joints
- Act on the first splits you see
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
What affects the cost of external mastic
Every job gets its own quote. This is what makes a difference:
- How many rooms, windows or areas are involved
- The number and length of the joints
- Any working-time requirements on site
- How easy the joints are to reach
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
To help us quote quickly, please include:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- The address or postcode of the job
- A few pictures by email, if you can
For a quote, send an email to info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.
The process
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 generally takes a few hours to a few days, depending on the length of joint and the access. Outside jobs in Stanley 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.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height

What external mastic looks like in Stanley
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as St Columba's Episcopal Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions from Stanley
What guarantee comes with external mastic in Stanley?
All our work, in Stanley and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is Stanley within the area you cover?
Yes, Stanley is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
How the job changes by surface
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.
