Common problems we fix in Birdston

Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.

Any of these means the joints need attention:

  • Sealant that has lost its bond to the brick or render
  • Brick movement joints where the sealant has split
  • Joints pointed up with cement by mistake
  • Gaps where render, brick and frames meet

If you live in an older home near Kirkintilloch, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Before booking anyone

  • When the joint can take water or movement
  • Whether they’re fully insured
  • Whether they seal over old material or remove it
  • How hidden problems are handled

Choosing a sealant specialist

External mastic for homes and businesses in Birdston

We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. Common call-outs are for rain getting behind render or cladding at a joint and leaking joints around cladding and façade panels, on render & cladding joints, concrete & block and brickwork movement joints.

In and around a place like Birdston, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.

You get a 12-month guarantee, the same in Birdston as everywhere else we work.

What we can’t put right

It helps to know what we cannot do:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Cracked brickwork or render that needs a builder or plasterer

If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

Surfaces we seal

  • Copings & trims
  • Façade panels
  • Joints between brick and frames
  • Render & cladding joints
  • Concrete & block
  • Brickwork movement joints

Should I try it myself first?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

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.

What external mastic looks like in Birdston

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Birdston is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.

Rented homes near Lenzie station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Kirkintilloch High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How do I get a quote for external mastic in Birdston?

It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.

I rent my home. Can I book you?

What is a movement joint?

It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.

How long should I leave it?

Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.

What affects the cost of external mastic

Every job gets its own quote. These are the things that affect it:

  • How many areas need sealing
  • The number and length of the joints
  • Whether old sealant or filler has to be cut out
  • The type of sealant required

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

Asking for a quote

When you call or email, it’s useful to know:

  • The problem you’ve noticed
  • Whether it’s a home or a business
  • Where the job is, and your postcode
  • How we’d reach the joints

To get a quote, drop us a line at info@mrmastic.co.uk with the location and a short description of the problem. You will have a clear quote before any work starts.

Why deal with it now?

Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. Around Birdston, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What we do, step by step

On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Around Birdston, distance and access matter more than parking. Tell us how to find the property and how to reach the work.

  1. First, the joints are inspected and the access agreed.
  2. Every bit of old sealant and any mortar or debris is cut out.
  3. The faces are brushed clean and primed where the product requires it.
  4. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.
