New Aberdeen External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for New Aberdeen, backed by a one-year guarantee. Ask us for a quote.
- Sealant pulling away from one side of the joint
- Moss and dirt in joints with no sealant left
- Failed seals between different materials
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before we start.
What you get with us
- ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet

- Quality sealants from Arbo and Everbuild
External mastic in New Aberdeen, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. Typical jobs include gaps where render, brick and frames meet and moss and dirt in joints with no sealant left, on façade panels, concrete & block and render & cladding joints.
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. In New Aberdeen, access needs planning, and work on shared parts may need the other owners’ agreement.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

New Aberdeen buildings and the weather
New Aberdeen is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Provost Skene's House (about 0.2 miles west) nearby, there’s older building stock in the area around New Aberdeen as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Robert Gordon's College, larger buildings have long runs of movement joint that eventually need resealing. Homes close to St Peter's RC Church and Presbytery include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
New Aberdeen is about 1 mile east of Aberdeen, in Aberdeen. New Aberdeen gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. New Aberdeen is one of 63 towns and villages in Aberdeen we cover for external mastic.
Work in AB11, AB24 and AB25 works the same way as everywhere else we cover. If you need external mastic at a property on Shoe Lane, Shore Lane and Water Lane or a nearby road, our applicators can take on the job.

Your questions about external mastic in New Aberdeen
Do you work for landlords with property near Aberdeen station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Does living near the coast affect external mastic in New Aberdeen?
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.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
How we quote for external mastic
There’s no set price list. What we look at:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- The type of sealant required
- Whether the work is at height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
To make quoting easier, please include:
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- Roughly how big the job is
- How we’d reach the joints

Surface by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Landlord and commercial work in New Aberdeen
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
When it isn’t the sealant
We won’t take on work that won’t last, so these are the limits:
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Joints between brick and frames
- Brickwork movement joints
- Concrete & block
- Copings & trims
- Render & cladding joints
- Façade panels
What we’re called out for in New Aberdeen
Buildings move more than people expect. 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.
If you can see any of these, it’s time to have the joints looked at:
- Joints where the bead has come unstuck
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
For landlords with property near Aberdeen station, outside joints that have cracked can let damp into a rental, so check them between lets.

How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. For a tenement in New Aberdeen, 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.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- 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.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
