External mastic for homes and businesses in Cawdor
For buildings in Cawdor, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Common call-outs are for rigid filler in a joint that should flex and sealant that has lost its bond to the brick or render, across copings & trims, joints between brick and frames and brickwork movement joints.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
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.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
- Never let anyone fill a movement joint with mortar
- Don’t let climbing plants root in the sealant
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation from start to finish. Outside jobs in Cawdor need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- 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.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

Walls and rooflines in Cawdor
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Around Cawdor, as everywhere, external mastic is only as good as the preparation behind it.

What else we do in Cawdor
What we are called out for in Cawdor
Some movement joints have been pointed up with mortar. The joint can’t move, so the wall cracks somewhere else instead.
The problems people generally mention when they call include:
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
- Failed seals between different materials
For landlords with property near Nairn station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Render that’s blown, hollow or coming away
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.
What we seal
- Façade panels
- Joints between brick and frames
- Copings & trims
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
Surface by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
Cawdor: your questions answered
Is Cawdor within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Nairn station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk and let us know what needs doing and where.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What affects the cost of external mastic
The quote reflects the job in front of us. We look at:
- Whether the work is at height
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before any work starts.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- The problem you’ve noticed
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
