How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. Outdoor work around Kinmundy depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

External mastic in Kinmundy
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. We work on render & cladding joints, joints between brick and frames and concrete & block, and common reasons people get in touch are leaking joints around cladding and façade panels and weeds or debris growing in open joints.
Outside joints can only be sealed when they’re dry, so work in Kinmundy depends on the weather. Let us know about access to every wall and roofline.
You are covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
After the cure time, these simple habits help:
- Point out the joints to other trades
- Have failed joints looked at early
- Keep water from gutters off the wall
- Walk round the building once a year and look at the joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
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.
How the job changes by surface
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. We reseal them with a sealant suited to the panel material.
Kinmundy buildings and the weather
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. 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.
Homes close to Newmachar Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as New Machar Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What we cannot put right
New sealant cannot fix everything, and we’ll tell you before we start. Sealant won’t put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
- Subsidence or other structural problems
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.
What we seal
- Façade panels
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Concrete & block
- Brickwork movement joints
Common problems we fix in Kinmundy
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Signs it’s time to call us include:
- Weathered mastic that no longer stretches
- Failed seals between different materials
- Plants rooting in failed movement joints
- Joints pointed up with cement by mistake
Rented homes near Dyce station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Leave it or put it right?
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What you get with us
- Anti-fungal silicone where joints get wet
- A choice of colours where the product allows
- We never seal over old sealant
- Fully insured
