External & façade joints in Whauphill, Dumfries and Galloway

- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
External mastic for homes and businesses in Whauphill
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. Typical jobs include joints with sealant missing in places and rigid filler in a joint that should flex, across copings & trims, joints between brick and frames and façade panels.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. In an older home around Whauphill, damp from a failed joint can get into timber and plaster.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

What sealant work cannot fix
In fairness, there are a few things sealant will not fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
- Cracking across the wall rather than at a joint

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Keep soil, plants and ivy away from the joints
- Leave the joints unpainted unless we have said otherwise
- Get split or bare joints resealed while the damage is small
- Show decorators and builders where the movement joints are
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
Common questions in Whauphill
Will you come out to Whauphill?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee comes with external mastic in Whauphill?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint can’t move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
When to call us in Whauphill
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
People usually contact us when they notice something like this:
- Failed sealant between panels on a façade
- Failed seals between different materials
- Sealant pulling away from one side of the joint
- Movement joints with cracked, split or missing sealant
Around Whauphill, as everywhere, external mastic is only as good as the preparation behind it.

Whauphill buildings and the weather
The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For jobs in and around Whauphill, choosing the right material for each joint is as important as a tidy finish.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation. Outside jobs in Whauphill need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
