What happens on the day
We keep the work tidy and contained to the area we’re working on. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. Outside jobs in Carberry need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- 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
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Keep children and pets away from the work area

Advice
About our external mastic in Carberry
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. If you have moss and dirt in joints with no sealant left and cracked joints where brick meets render or frames, we can put it right, whatever the surface.
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.
Big or small, it’s backed by our one-year guarantee in Carberry and across East Lothian.

Will it make a mess?

When is the sealant fully cured?

Should I try DIY first?

Surface by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Render that’s blown, hollow or coming away
- Structural movement, which needs a surveyor or engineer
- Cracked brickwork or render that needs a builder or plasterer
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
What we seal
- Render & cladding joints
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
- Façade panels
- Copings & trims
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Signs you need external mastic in Carberry
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
Keep an eye out for these signs:
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
- Damp patches traced to an open external joint
If you let a flat or house near Wallyford station, split movement joints are easy to miss on a rental until damp shows inside.

External mastic in Carberry: local notes
Carberry is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Managing a site like Loretto School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Historic houses such as Hamilton House, about 3.2 miles north-east, show how far back building around Carberry goes.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Get split or bare joints resealed while the damage is small
- Keep water from gutters off the wall
- Do not let climbing plants root in the sealant
- Keep movement joints as flexible joints, not mortar
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
