External mastic in Whitehills

Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We work on façade panels, concrete & block and brickwork movement joints, and people most often call us about joints pointed up with cement by mistake and failed sealant between panels on a façade.

External sealant needs dry surfaces, so outdoor work around Whitehills is planned around the weather. Tell us how to reach each wall, gutter and roofline.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.

Why deal with it now?

It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Around Whitehills, 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.

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear quote before work begins.

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How the visit works

There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the building. Outdoor work around Whitehills depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.

  1. We inspect the joints and agree which need resealing and how they’ll be reached.
  2. Old sealant and any debris are cut and raked out.
  3. Both sides are cleaned back to sound material and primed if needed.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Tell us about access, such as stairs, a lift or high-level joints
  • Where the joints are inside, avoid wetting them before we arrive

What the job involves on each surface

Cladding and façade panels

Cladding and façade panels are generally separated by sealed joints. We reseal them with a sealant suited to the panel material.

Concrete and blockwork

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

Whitehills: your questions answered

Do you cover Whitehills for external mastic?

Yes, Whitehills is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.

Do you cover smaller places like Whitehills?

Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you seal joints between render and window frames?

Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.

Is it OK to seal over old sealant?

No, because it fails. The old sealant always comes out first.

Can you reach joints on upper floors?

Each building is different. Tell us the height, the number of joints and what’s below them, and we’ll confirm what access is needed.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that normally means someone at home.

How long should I leave it?

That depends on the sealant used, so please follow the time we give you.

Do you guarantee your work?

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

When to call us in Whitehills

The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.

People usually contact us after spotting one of these:

  • Plants rooting in failed movement joints
  • Rain getting behind render or cladding at a joint
  • Sealant that has lost its bond to the brick or render
  • Hard, crazed mastic that has stopped moving

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

Before booking anyone

  • Is the old sealant removed completely?
  • What insurance they hold
  • Which colour the sealant will be
  • Whether the sealant suits the joint

Our hiring checklist

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Ask before painting over external sealant
  • Get split or bare joints resealed while the damage is small
  • Keep water from gutters off the wall
  • Show decorators and builders where the movement joints are

Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.

An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
