Should I try DIY first?

How we handle external mastic in Barrhill
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include joints where the bead has come unstuck and rain getting behind render or cladding at a joint, across concrete & block, render & cladding joints and joints between brick and frames.
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.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

External mastic in Barrhill: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For an older house near a landmark such as Former Arnsheen Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Barrhill station, split movement joints are easy to miss on a rental until damp shows inside.
Barrhill is about 17 miles north-east of Stranraer, in South Ayrshire. Barrhill gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Barrhill is one of 52 places in South Ayrshire we cover.

How we quote for external mastic
Call for a quick quote. What matters most is:
- The old material and how stubborn it is
- Any working-time requirements on site
- Whether the work is at height
- Which sealant suits the joint
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- The rough size of the job
- Whether it has been sealed before
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
If you are in Barrhill and need external mastic, send an email to info@mrmastic.co.uk. Tell us what the problem is and where, and you will get a clear quote before we start.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Tell anyone working on the walls about the movement joints
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
- Make sure movement joints aren’t pointed over
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.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
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, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Clear the area around the work

What else we do in Barrhill
Landlords, agents and businesses in Barrhill
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.
Why it’s worth doing now in Barrhill
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.
