Keith External Mastic
Movement joints in Keith need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.

- Sealant pulling away from one side of the joint
- Damp patches traced to an open external joint
Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. Around Keith, water from a failed joint in an older stone home can soak into timber and plaster.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

External mastic for homes and businesses in Keith
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. We work on brickwork movement joints, façade panels and render & cladding joints, and common reasons people get in touch are leaking joints around cladding and façade panels and moss and dirt in joints with no sealant left.
Outside joints can only be sealed when they’re dry, so work in Keith depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
All of our work is guaranteed for twelve months, in Keith and everywhere else we cover.

What external mastic looks like in Keith
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. 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 St Rufus Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Keith Grammar School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Do you need external mastic in Keith?
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Most people get in touch when they notice something like this:
- Brick movement joints where the sealant has split
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
For landlords with property near Keith station, split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- Which sealant they’ll use, and why
- What the cure time is
- Are they insured?
- Whether they seal over old material or remove it
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Movement that is more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Concrete & block

- Render & cladding joints
How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Tell us what the building has when you get in touch.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access. Outside jobs in Keith need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
How to prepare
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in

Common questions in Keith
Do you work for landlords with property near Keith station?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Do you cover smaller places like Keith?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is there a guarantee?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
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.
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.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Are you insured?
Yes. We are fully insured.
Can I do it myself?
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, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Leave the joints unpainted unless we have said otherwise
- Make sure movement joints aren’t pointed over
- Deal with leaking gutters that soak the joints below
- Wash walls gently around the sealant
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
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, so it’s worth resealing at the first signs.
