Problem with your movement joints in Cottown? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.

External mastic in Cottown
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. If you’re dealing with panel joints letting water in and hard, crazed mastic that has stopped moving, we can help.
In and around a place like Cottown, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
Whatever the size of the job, it’s backed by our 12-month guarantee in Cottown and across Aberdeenshire.

How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
How the visit works
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take anything from a few hours to several days, depending on the building. Outside jobs in Cottown need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Plan for the work area to be out of bounds to pets and children

Advice
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Walk round the building once a year and look at the joints
- Fix overflowing gutters above sealed joints
- Do not let climbing plants root in the sealant
- Leave the joints unpainted unless we’ve said otherwise
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Questions from Cottown
Is Cottown in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Cottown is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Can you help a landlord with a rental near Kintore station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you reach joints on upper floors?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
Walls and rooflines in Cottown
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Rented homes near Kintore station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Kemnay Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
