About our external mastic in Kirk Yetholm
Low-level joints can usually 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’s needed to reach them safely. If you are dealing with joints pointed up with cement by mistake and old sealant gone brittle and cracked, we can help, whatever the surface.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
Every job comes with our 12-month guarantee.

Common problems we fix in Kirk Yetholm
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Signs it’s time to call us include:
- Joints where the bead has come unstuck
- Gaps where render, brick and frames meet
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
If you live in an older home near Kirk Yetholm Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Can I do it myself?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. For a place like Kirk Yetholm, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints

Walls and rooflines in Kirk Yetholm
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. 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.

FAQs for Kirk Yetholm
What guarantee comes with external mastic in Kirk Yetholm?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Kirk Yetholm in your area for external mastic?
Yes. We work across all of Scotland, and Kirk Yetholm is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Clear growth from the base of walls and joints
- Show decorators and builders where the movement joints are
- Leave the joints unpainted unless we’ve said otherwise
- Act on the first splits you see
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, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
What affects the cost of external mastic
The quote reflects the job in front of us. We take into account:
- Whether there’s mould to deal with
- The size of the job
- The product the joint needs
- Whether old sealant or filler has to be cut out
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start.
What we need to know
There’s no need for technical detail. Just tell us:
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Access, such as stairs, a lift or height
- Roughly how big the job is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
