About our external mastic in Glengarnock
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. We work on brickwork movement joints, concrete & block and joints between brick and frames, and the jobs we see most are rain getting behind render or cladding at a joint and old sealant gone brittle and cracked.
Outside joints can only be sealed when they’re dry, so work in Glengarnock depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
All of our work is guaranteed for twelve months, in Glengarnock and everywhere else we cover.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Around Glengarnock, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on

Advice
Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

What we’re called out for in Glengarnock
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Common reasons people contact us are:
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
- Old sealant gone brittle and cracked
For an older house near a landmark such as Kilbirnie Auld Kirk, older walls, gutters and the joints where extensions meet them need a flexible sealant.

- Which sealant they’ll use, and why
- What the quote includes, VAT included or not
- Whether they’re fully insured
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.

How to look after the new joints
Aftercare is simple:
- Keep high-pressure jets off the joints
- Ask before painting over external sealant
- Don’t let climbing plants root in the sealant
- Keep water from gutters off the wall
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.
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.

Of course. Ask your landlord first, and we can send them the quote if that helps.
Walls and rooflines in Glengarnock
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Rented homes near Glengarnock station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
