- Movement joints filled with mortar instead of sealant
External mastic in Lauriston
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We are often asked to deal with failed seals between different materials and weathered mastic that no longer stretches, across render & cladding joints, joints between brick and frames and façade panels.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. In Lauriston, work on shared parts of a tenement is usually agreed between owners, often with a factor arranging it.

FAQs for Lauriston
Is external mastic in a coastal place like Lauriston any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
How do repairs to the shared parts of a tenement in Lauriston get organised?
The owners of the flats generally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
How do you reach high-level joints?
It depends on the building. Send us pictures and a rough idea of the height and we will confirm how they can be reached safely.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
Do you come to Lauriston?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
What else we do in Lauriston
The process
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. For a tenement in Lauriston, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Tell us about any water getting in
- Mention any parking rules near the property
- Keep children and pets away from the work area

Advice
For landlords and businesses
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear growth from the base of walls and joints
- Leave the joints unpainted unless we have said otherwise
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
How we quote for external mastic
The quote reflects the job in front of us. We take into account:
- How many rooms, windows or areas are involved
- The size of the job
- Any working-time requirements on site
- Mould in or behind the old joints
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Any access issues, like height or stairs
- Whether it has been sealed before
- What’s wrong with the joints now
- Where the property is
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, send an email to info@mrmastic.co.uk.
When something else is needed
A few problems are outside what sealant work can do:
- Render that’s blown, hollow or coming away
- Subsidence or other structural problems
- Cracking across the wall rather than at a joint
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before booking.
Surfaces we seal
- Brickwork movement joints
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Façade panels
What we’re called out for in Lauriston
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and make things worse.
Any of these means the joints need attention:
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
- Failed sealant between panels on a façade
- Moss and dirt in joints with no sealant left
If you let a flat or house near Edinburgh Waverley station, split movement joints are easy to miss on a rental until damp shows inside.
What to look for in a quote
- Whether VAT is included
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- How the colour is chosen
How the job changes by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
External mastic in Lauriston: local notes
Lauriston is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. For listed homes and conservation areas, check with the council before changing how windows or walls look.
Homes close to Lauriston Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Edinburgh School of Architecture and Landscape Architecture? Then its movement joints, gutters and trims need looking after like any other building’s.
