Outside joints around Greendykes
Greendykes is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Whitefoord House (about 2.5 miles north-west) are a reminder that the area around Greendykes has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Brunstane station? Then split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Robin Chapel, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Castlebrae Community High School? Then its movement joints, gutters and trims need looking after like any other building’s.

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it.

Inside a flat in Greendykes, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.

Common questions in Greendykes
How is work on the outside of a tenement in Greendykes normally arranged?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Your title deeds will say who owns the windows.
Does the coastal weather in Greendykes affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
How long does the job take?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we will tell you how long to expect.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Walk round the building once a year and look at the joints
- Fix overflowing gutters above sealed joints
- Have failed joints looked at early
- Show decorators and builders where the movement joints are
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. For landlords in Greendykes, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

When it is not the sealant
To be straight with you, there are a few things sealant will not fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
