- Joints with sealant missing in places
- Weathered mastic that no longer stretches
- Gaps where render, brick and frames meet
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Fix overflowing gutters above sealed joints
- Don’t let climbing plants root in the sealant
- Never let anyone fill a movement joint with mortar
- Act on the first splits you see
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
External mastic for homes and businesses in Colinton
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on copings & trims, concrete & block and render & cladding joints, and the jobs we see most are gaps where render, brick and frames meet and plants rooting in failed movement joints.
On a four-storey tenement, gutter joints are a long way from the street, and a slow drip can stain and soak the stone for a long time before it’s spotted. In Colinton, access needs planning, and work on shared parts may need the other owners’ agreement.
Our work is backed for twelve months, in Colinton and everywhere else we cover.

Colinton questions
Do you cover Colinton for external mastic?
Yes. We work across all of Scotland, and Colinton is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
How is work on the outside of a tenement in Colinton normally arranged?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t.
Where do you work from?
Mr Mastic is based in Crawley. We cover Colinton and the rest of Edinburgh, along with the rest of our area.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we’ll tell you how long to expect.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Walls and rooflines in Colinton
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. Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. 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.
In the older streets around Colinton Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Kingsknowe station, split movement joints are easy to miss on a rental until damp shows inside.

Around Colinton

The countryside around Colinton includes Duddingston Loch and Craiglockhart Hill.
Do you need external mastic in Colinton?
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
It’s worth asking for a quote if you see:
- Failed sealant between panels on a façade
- Weathered mastic that no longer stretches
- Cracked joints where brick meets render or frames
- Sealant pulling away from one side of the joint
If you look after a building such as Army School of Bagpipe Music and Highland Drumming, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.

What affects the quote in Colinton
There’s no set price list. The quote depends on:
- The old material and how stubborn it is
- Any mould that needs treating
- Any working-time requirements on site
- The size of the job
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours for a handful of joints, longer for a whole elevation. Parking in city streets around Colinton can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
