Cardrona External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Cardrona and across the Scottish Borders. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
Surface by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
About our external mastic in Cardrona
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. We are often asked to deal with gaps where render, brick and frames meet and leaking joints around cladding and façade panels, across concrete & block, brickwork movement joints and joints between brick and frames.
In and around a place like Cardrona, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes anything from a few hours to several days, depending on the building, depending on the size of the job. Around Cardrona, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

Advice
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. Around Cardrona, water from a failed joint in an older stone home can soak into timber and plaster.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk and we will talk you through it.
What you get with us

Walls and rooflines in Cardrona
Plenty of Scottish homes have harled walls, 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.
In and around Cardrona, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. Homes close to William Cree Memorial Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Your questions about external mastic in Cardrona
What guarantee comes with external mastic in Cardrona?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Cardrona for external mastic?
Yes, Cardrona is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
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. We pick a colour that works with both materials.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
What we cannot put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

Quotes for external mastic in Cardrona
Call for a quick quote. What matters most is:
- The old material and how stubborn it is
- How many areas need sealing
- Which sealant suits the joint
- Whether the work is at height
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- A few pictures by email, if you can
- Whether it has been sealed before
- Where the property is
- The problem you’ve noticed
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check the sealant is paintable before painting near it
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Avoid pressure-washing directly into sealant joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
