External mastic in Midstocket, done properly
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 joint doesn’t stand out. We work on copings & trims, render & cladding joints and façade panels, and people most often call us about brick movement joints where the sealant has split and movement joints filled with mortar instead of sealant.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention any parking rules near the property
- Move anything stored near the joints
- Mention any tricky access

Your questions about external mastic in Midstocket
I let a flat near Aberdeen station. Can you help?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Does living near the coast affect external mastic in Midstocket?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.
Do you cover Midstocket?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Façade panels
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints
- Concrete & block
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

What external mastic looks like in Midstocket
Midstocket is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Aberdeen’s nickname, the Granite City, comes from its stone buildings, and sealing against granite needs clean, sound edges and a sealant that suits stone.
Rented homes near Aberdeen station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Oakbank School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around St Ninian's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Surface by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Send us any details you have about the façade.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
Looking after it afterwards
After the cure time, these simple habits help:
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
- Don’t let climbing plants root in the sealant
- Fix overflowing gutters above sealed joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
