External mastic in Craigiebank

How we handle external mastic in Craigiebank

Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. If you have leaking joints around cladding and façade panels and hard, crazed mastic that has stopped moving, we can help, on joints between brick and frames, copings & trims and façade panels alike.

On a four-storey tenement, gutter joints are a long way from the street, and a slow drip can stain and soak the stone for a long time before it’s spotted. For a building in Craigiebank, access is planned first, and shared parts may need the other owners to agree.

All of our work is guaranteed for twelve months.

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Common questions in Craigiebank

How is work on the outside of a tenement in Craigiebank usually arranged?

Shared parts of a tenement, such as the roof and outside walls, are normally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.

I let a flat near Dundee station. Can you help?

Yes, we work for letting agents and landlords. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.

Are you fully insured?

Yes, we’re fully insured.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you work at height?

Each building is different. Tell us the height, the number of joints and what’s below them.

How long does external mastic take?

A typical job takes a few hours for a handful of joints, longer for a whole elevation, including the preparation. Your quote will say how long we expect yours to take.

What do you need from me for a quote?

Just the basics: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.

Will it make a mess?

Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.

How to look after the new joints

How long the joints last depends on use and care. Here’s what we suggest:

  • Tell anyone working on the walls about the movement joints
  • Check external joints each spring
  • Leave the joints unpainted unless we’ve said otherwise
  • Have failed joints looked at early

Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.

If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

What happens if it’s left?

Resealing a run of joints in one go is generally better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. For landlords in Craigiebank, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.

What you pay reflects the work, not guesswork. That is why we ask a few questions first.

Do you need external mastic in Craigiebank?

Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.

If you can see any of these, it’s time to have the joints looked at:

  • Rain getting behind render or cladding at a joint
  • Movement joints with cracked, split or missing sealant
  • Sealant pulling away from one side of the joint
  • Joints pointed up with cement by mistake

For site and facilities teams at buildings such as Craigie High School, its movement joints, gutters and trims need looking after like any other building’s.

What your quote should include

  • Whether the sealant suits the joint
  • How the surfaces are prepared before sealing
  • Is VAT in the price?
  • What the cure time is

10 questions to ask before you book

What affects the quote in Craigiebank

Jobs vary more than people expect. The main factors:

  • How easy the joints are to reach
  • Any working-time requirements on site
  • Any mould that needs treating
  • The size of the job

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Asking for a quote

To make quoting easier, please include:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Roughly how big the job is
  • Photos by email, if that is easy
  • The address or postcode of the job

For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work and give you a clear price.

How the job changes by surface

Concrete and blockwork

Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant is not too deep.

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.

External mastic in Craigiebank: local notes

Craigiebank 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. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.

Letting a property close to Dundee station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Craigiebank Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we do, step by step

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours to a few days, depending on the length of joint and the access. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Craigiebank, tell us the floor, how the door entry system works and where we can park nearby.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. The old mastic and anything lodged in the joint is removed.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height
  • Tell us if parking is tricky
