Your questions about external mastic in Penninghame
Do you cover smaller places like Penninghame?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is external mastic in Penninghame guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we’ll do them. Give us some details and we’ll confirm the access.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Where are you based?
We work from Crawley. We cover Penninghame and the rest of Dumfries and Galloway.
Can you seal over the old sealant?
No. The old sealant always comes out first.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint does not draw the eye.
External mastic in Penninghame
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, and when it fails, the wall takes the strain and water finds a way in. We work on copings & trims, joints between brick and frames and façade panels, and people most often call us about joints where the bead has come unstuck and brick movement joints where the sealant has split.
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.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

How the visit 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. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like Penninghame may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- 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.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules

What affects the quote in Penninghame
The quote reflects the job in front of us. We look at:
- The number and length of the joints
- The number of rooms or windows
- Working hours on commercial sites
- The product the joint needs
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

What external mastic looks like in Penninghame
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. Penninghame is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
Around Penninghame, as everywhere, external mastic is only as good as the preparation behind it.
Penninghame is about 21 miles east of Stranraer, in Dumfries and Galloway. Homes, rented property, offices and hotels in Penninghame can book us for external mastic, old or new, large or small. Every job comes with our 12-month guarantee. We cover 138 towns and villages across Dumfries and Galloway, from the larger towns to small villages. We also work in Glasgow, about 60 miles from Penninghame.

Around Penninghame
Around Penninghame, our work takes us to homes and buildings near Wood of Cree and the streets around them. Nearby you will also find Newton Stewart Hospital (3.2 miles south-east) and Machermore Castle (3.7 miles south-east). Not far away are Wood of Cree RSPB reserve and Loch Eldrig.
Honest limits
It helps to know what we cannot do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Copings & trims
- Façade panels
- Render & cladding joints
- Joints between brick and frames
- Brickwork movement joints
- Concrete & block
What we are called out for in Penninghame
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
It’s worth asking for a quote if you see:
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
- Rigid filler in a joint that should flex
- Leaking joints around cladding and façade panels
For an older house near a landmark such as All Saints Episcopal Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a place like Penninghame, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
Why book with us
- We are fully insured
- Anti-fungal silicone where joints get wet
- A choice of colours where the product allows
- Colour agreed with you before any work starts

Aftercare tips
So the new joints stay in good condition:
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we’ve said otherwise
- Clear growth from the base of walls and joints
- Get split or bare joints resealed while the damage is small
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
