DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
About our external mastic in Gracemount
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. If you have rigid filler in a joint that should flex and damp patches traced to an open external joint, we can put it right, whatever the surface.
Gutters and downpipes on tall city tenements are a long way up, so a leaking joint can run down the stone for months before anyone notices. For a building in Gracemount, access is planned first, and shared parts may need the other owners to agree.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
After the cure time, these simple habits help:
- Avoid pressure-washing directly into sealant joints
- Keep water from gutters off the wall
- Act on the first splits you see
- Check external joints each spring
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

Surface by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Inside a flat in Gracemount, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- 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.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Tell us about any water getting in
- Mention any tricky access
- Mention any parking rules near the property

Advice
Honest limits
New sealant can’t fix everything, and we will tell you before any work starts. It won’t solve:
- Cracked brickwork or render that needs a builder or plasterer
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.

Outside joints around Gracemount
Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Your title deeds say which parts are shared. 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 let a flat or house near Shawfair station, outside joints that have cracked can let damp into a rental, so check them between lets. Historic houses such as Melville Castle, about 2.3 miles south-east, show how far back building around Gracemount goes. Managing a site like Gracemount High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Your questions about external mastic in Gracemount
How is work on the outside of a tenement in Gracemount generally arranged?
Shared parts of a tenement, such as the roof and outside walls, are generally 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.
I let a flat near Shawfair station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
How long does external mastic last?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply send an email to info@mrmastic.co.uk.
