External Mastic in Piperdam
Sealing brickwork movement joints, render, cladding and façade joints for Piperdam, backed by a 12-month guarantee. Call for a quick quote.
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
- Weeds or debris growing in open joints
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

How we handle external mastic in Piperdam
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. Typical jobs include weeds or debris growing in open joints and failed seals between different materials, across brickwork movement joints, façade panels and render & cladding joints.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What external mastic looks like in Piperdam
Dundee sits on the north bank of the Tay, and much of its older housing is sandstone tenements, so movement joints and outside wall joints on walls facing the water can take plenty of weather. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
If you live in an older home near Lundie Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Deal with leaking gutters that soak the joints below
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
- Act on the first splits you see
Have a quick look at the joints each spring. 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. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Around Piperdam, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.

- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall

Piperdam: your questions answered
Is Piperdam within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Piperdam for external mastic?
Yes. We work across all of Scotland, and Piperdam is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Signs you need external mastic in Piperdam
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
The problems people generally mention when they call include:
- Failed seals between different materials
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
Letting a property close to Invergowrie station? Then split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- Whether all the old sealant comes out first
- Whether the sealant suits the joint
- How long to leave it before use
- Who turns up on the day
