About our external mastic in Eddleston
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. We work on façade panels, copings & trims and concrete & block, and people most often call us about failed sealant between panels on a façade and brick movement joints where the sealant has split.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
You are covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure movement joints aren’t pointed over
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
- Clear growth from the base of walls and 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.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.

External mastic in Eddleston: local notes
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Eddleston, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It generally takes anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can

FAQs for Eddleston
Is external mastic in Eddleston guaranteed?
All our work, in Eddleston and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Eddleston for external mastic?
Yes, Eddleston 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.
Can a movement joint be filled with mortar?
No. Cement or mortar can’t stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Where are you based?
We work from Crawley. We cover Eddleston and the rest of the Scottish Borders, along with the rest of our area.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.

Signs you need external mastic in Eddleston
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Keep an eye out for any of the following:
- Water getting into walls through failed joints
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Old sealant gone brittle and cracked
Homes close to Eddleston Parish Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What the job involves on each surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
When something else is needed
We will always be straight with you, so here’s what sealant can’t fix:
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
