Do you need external mastic in Aberdeen?
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
Rented homes near Aberdeen station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

External mastic in Aberdeen, done properly
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. We work on copings & trims, joints between brick and frames and render & cladding joints, and people most often call us about failed seals between different materials and moss and dirt in joints with no sealant left.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. In Aberdeen, those joints dry out over time and let water in behind the render or cladding.
Your job is guaranteed for a year, as with all our work.
The process
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation. Parking in city streets around Aberdeen can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Failed render or damaged cladding panels
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before booking.

External mastic in Aberdeen: local notes
Aberdeen 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. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
For an older house near a landmark such as Rutherford Church And Church Hall, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Aberdeen Grammar School, larger buildings have long runs of movement joint that eventually need resealing.

Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Leave the joints unpainted unless we have said otherwise
- Don’t let climbing plants root in the sealant
- Avoid pressure-washing directly into sealant joints
- Keep water from gutters off the wall
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Private landlords in Aberdeen 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.

Aberdeen questions
Is external mastic in a coastal place like Aberdeen any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
How do repairs to the shared parts of a tenement in Aberdeen get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. A flexible sealant is the right fill.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What affects the cost of external mastic
Every job gets its own quote. This is what makes a difference:
- The amount of work
- Mould in or behind the old joints
- Any working-time requirements on site
- How many areas need sealing
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Pictures of the joints, sent by email
- The type of property
- Whether it has been sealed before
- Roughly how big the job is
