External mastic in Garthdee, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. Typical jobs include sealant pulling away from one side of the joint and panel joints letting water in, across joints between brick and frames, concrete & block and render & cladding joints.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. In Garthdee, work on shared parts of a tenement is generally agreed between owners, often with a factor arranging it.
Big or small, you get the same one-year guarantee.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building, and the area is left clean. In a city area like Garthdee, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.

Common problems we fix in Garthdee
Every building moves. 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.
These are the problems we are asked about most:
- Cracked joints where brick meets render or frames
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
- Movement joints filled with mortar instead of sealant

Outside joints around Garthdee
Garthdee is close to 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. 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.
Historic houses such as Friendville, about 0.7 miles north, show how far back building around Garthdee goes, and older homes nearby need a sealant that suits their walls. If you look after a building such as Airyhall Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracking across the wall rather than at a joint
- Damp that isn’t coming from the joint

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Private landlords in Garthdee must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.
Why book with us
- A choice of colours where the product allows
- Tidy, careful work
- Homes, businesses and hotels
- Anti-fungal silicone where joints get wet
How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.
FAQs for Garthdee
How is work on the outside of a tenement in Garthdee generally arranged?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can you help a landlord with a rental near Aberdeen station?
Yes, we work for letting agents and landlords. 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 work begins.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Is there a guarantee?
Yes. All our work carries our 12-month guarantee.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Do you work at height?
It depends on the building. Send us pictures and a rough idea of the height.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Get split or bare joints resealed while the damage is small
- Walk round the building once a year and look at the joints
- Never let anyone fill a movement joint with mortar
- Ask before painting over external sealant
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
