External mastic for homes and businesses in Kincorth
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. Common call-outs are for brick movement joints where the sealant has split and rain getting behind render or cladding at a joint, across concrete & block, joints between brick and frames and copings & trims.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. For a tenement in Kincorth, repairs to shared parts are generally agreed between the owners, often through a property factor.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What the job involves on each surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Looking after it afterwards
After the cure time, these simple habits help:
- Show decorators and builders where the movement joints are
- Keep soil, plants and ivy away from the joints
- Deal with leaking gutters that soak the joints below
- Get split or bare joints resealed while the damage is small
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.

External mastic in Kincorth: local notes
Kincorth 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’s 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.
If you live in an older home near Ruthrieston South Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Lochside Academy? Then its movement joints, gutters and trims need looking after like any other building’s.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Kincorth, tell us the floor, how the door entry system works and where we can park nearby.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can

Common problems we fix in Kincorth
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
People usually contact us after spotting one of these:
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
- Movement joints filled with mortar instead of sealant
- Failed seals between different materials
If you let a flat or house near Aberdeen station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Kincorth questions
Do you work for landlords with property near Aberdeen station?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Kincorth?
It normally goes through the owners together, or through the factor if the building has one. 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.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
Do you work at height?
It depends on the building. Tell us the height, the number of joints and what’s below them.
How much does external mastic cost in Kincorth?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
What should I tell you?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
What we cannot put right
To be straight with you, some problems need a different trade:
- Failed render or damaged cladding panels
- Damp that is not coming from the joint
- Movement that is more than a sealant joint can take
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
