External mastic in Dreghorn
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. If you’re dealing with rain getting behind render or cladding at a joint and failed sealant between panels on a façade, we can help, on concrete & block, copings & trims and brickwork movement joints alike.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Common problems we fix in Dreghorn
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Common reasons people contact us include:
- Plants rooting in failed movement joints
- Failed sealant between panels on a façade
- Joints where the bead has come unstuck
- Rigid filler in a joint that should flex
Girgenti House, about 3.6 miles north, is one of the historic houses in the wider area around Dreghorn, and older homes nearby need a sealant that suits their walls.
What to look for in a quote
- Whether they seal over old material or remove it
- The length of the guarantee
- Are they insured?
- How the surfaces are prepared before sealing
What happens on the day
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere like Dreghorn may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

External mastic in Dreghorn: local notes
Dreghorn is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Managing a site like Greenwood Academy? Then its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Irvine station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Near you in Dreghorn

Why act early in Dreghorn
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, so it pays to do it properly once. In an older home around Dreghorn, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

How the job changes by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Aftercare tips
After the cure time, these simple habits help:
- Get split or bare joints resealed while the damage is small
- Show decorators and builders where the movement joints are
- Make sure movement joints are not pointed over
- Fix overflowing gutters above sealed joints
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
