External mastic in Riggend

External mastic in Riggend, done properly

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. Typical jobs include weathered mastic that no longer stretches and movement joints filled with mortar instead of sealant, on joints between brick and frames, copings & trims and façade panels.

In and around a place like Riggend, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.

There’s a 12-month guarantee on every job, large or small.

For landlords and businesses

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

What the job involves on each surface

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.

Copings and trims

A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.

Why deal with it now?

Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Around Riggend, water from a failed joint in an older stone home can soak into timber and plaster.

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk and we’ll talk you through it.

What happens on the day

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  1. We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
  2. The old mastic and anything lodged in the joint is removed.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

How to prepare

  • Keep pets and children clear of the area while we work
  • Tell us about any water getting in
  • Let us know about stairs, lifts or work at height

Advice

Signs you need external mastic in Riggend

Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.

Look out for any of the following:

  • Hard, crazed mastic that has stopped moving
  • Movement joints with cracked, split or missing sealant
  • Rain getting behind render or cladding at a joint
  • Rigid filler in a joint that should flex

If you let a flat or house near Greenfaulds station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Before you book anyone

  • Which colour the sealant will be
  • Is VAT in the price?
  • What guarantee comes with the work
  • Who turns up on the day

Choosing a sealant specialist

Looking after it afterwards

So the new joints stay in good condition:

  • Walk round the building once a year and look at the joints
  • Make sure movement joints aren’t pointed over
  • Get split or bare joints resealed while the damage is small
  • Keep water from gutters off the wall

Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants are not designed to be painted.

Act while the splits are small. At that stage it’s a simple cut out and reseal.

FAQs for Riggend

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

What’s an expansion joint in brickwork?

Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.

Should I point up the gap in my brickwork?

No, not where the gap is a movement joint. Pointing it stops it working. We’ll reseal it with a flexible sealant.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

When is the sealant fully cured?

Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.

How often do external joints need resealing?

That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.

How long will you be here?

It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll give you a better idea when we quote.

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

If you do try it yourself, take your time over the 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.

What external mastic looks like in Riggend

Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.

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