- Plants rooting in failed movement joints

- Movement joints with cracked, split or missing sealant
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Warriston may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Related advice
External mastic in Warriston, done properly
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. If you’re dealing with damp patches traced to an open external joint and leaking joints around cladding and façade panels, we can put it right, on joints between brick and frames, brickwork movement joints and concrete & block alike.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Leave it or put it right?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

Warriston: your questions answered
Can you do external mastic in Warriston?
Yes. We work across all of Scotland, and Warriston is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
Will you come out to Warriston?
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.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
What does external mastic cost?
It depends on the job, so we quote each one individually. To get one, email us at info@mrmastic.co.uk and let us know what needs doing and where.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Quotes for external mastic in Warriston
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- How easy the joints are to reach
- The number and length of the joints
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
Asking for a quote
There’s no need for technical detail. Just tell us:
- The problem you’ve noticed
- The type of property
- A few photos by email, if you can
- If someone has resealed it before
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved and give you a clear quote.
Walls and rooflines in Warriston
The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you look after a building such as Currie High School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Curriehill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Other services in Warriston
Signs you need external mastic in Warriston
UV, rain and frost all age exterior sealant. 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.
The most common problems we see are:
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
- Weathered mastic that no longer stretches
- Sealant pulling away from one side of the joint
Homes close to St Mary's Episcopal Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
- What happens if they find a problem under the old sealant
- Which colour the sealant will be
How the job changes by surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
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.
