About our external mastic in Mayfield
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We’re often asked to deal with rain getting behind render or cladding at a joint and joints with sealant missing in places, across brickwork movement joints, concrete & block and render & cladding joints.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. In Mayfield, work on shared parts of a tenement is normally agreed between owners, often with a factor arranging it.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What else we do in Mayfield
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on the building, including the tidy-up. Parking in city streets around Mayfield can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

Advice
Do you need external mastic in Mayfield?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Any of these means the joints need attention:
- Sealant pulling away from one side of the joint
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Weeds or debris growing in open joints
If you look after a building such as Royal Blind School, its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before booking
- Whether all the old sealant comes out first
- What happens if the job turns out different
- Whether they’re fully insured
- When the joint can take water or movement
Your questions about external mastic in Mayfield
Does living near the coast affect external mastic in Mayfield?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
How do repairs to the shared parts of a tenement in Mayfield get organised?
Shared parts of a tenement, such as the roof and outside walls, are normally repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Your title deeds will say who owns the windows.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Are you fully insured?
Yes. Full insurance covers our work.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
Why act early in Mayfield
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Mayfield, damp can travel a long way before it shows.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

What the job involves on each surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Mayfield and across Edinburgh. Several sites can go on one quote, and we’re fully insured for the work.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What external mastic looks like in Mayfield
Mayfield is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you let a flat or house near Edinburgh Waverley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Craigmillar Park Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
