External mastic for homes and businesses in Warriston
On houses, flats and commercial buildings across Warriston, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on concrete & block, copings & trims and façade panels, and the jobs we see most are joints where the bead has come unstuck and old sealant gone brittle and cracked.
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. For a building in Warriston, access is planned first, and shared parts may need the other owners to agree.
Our work is backed for twelve months, in Warriston and everywhere else we cover.

Why act early in Warriston
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Wind-driven rain gets into any failed joint on the outside of a city building, and in Warriston, damp can spread through stone and plaster before anyone sees it.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
Why us?
- Fully insured
- A sealant colour to suit the surroundings
- Old sealant always removed completely
- You choose the colour before work begins

Warriston buildings and the weather
Warriston is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Your title deeds say which parts are shared.
Managing a site like Drummond Community High School? Then larger buildings have long runs of movement joint that eventually need resealing. Homes close to St Serf's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Aftercare tips
After the cure time, these simple habits help:
- Keep high-pressure jets off the joints
- Act on the first splits you see
- Keep soil, plants and ivy away from the joints
- Check external joints each spring
Don’t paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.

The process
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building. Parking in city streets around Warriston 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.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints

Your questions about external mastic in Warriston
I let a flat near Edinburgh Waverley station. Can you help?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
How is work on the outside of a tenement in Warriston usually 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.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What do you need from me for a quote?
A short description and the location. If we need more, we will ask.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Common problems we fix in Warriston
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
Any of these means the joints need attention:
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
- Movement joints filled with mortar instead of sealant
Letting a property close to Edinburgh Waverley station? Then split movement joints are easy to miss on a rental until damp shows inside.
