Questions from Cairston

Is Cairston within the area you cover?

Yes, Cairston is covered. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.

Does living near the coast affect external mastic in Cairston?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and you’ll get one quote.

Is the work guaranteed?

Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.

Do you hold any approvals?

Yes. We are approved under the ARBOMaster scheme.

What should I tell you?

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply drop us a line at info@mrmastic.co.uk.

How much does external mastic cost in Cairston?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

Is there any odour?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

External mastic for homes and businesses in Cairston

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 all tend to fail early. We strip the joint back and start again. If you are dealing with panel joints letting water in and rigid filler in a joint that should flex, we can help, whatever the surface.

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

Whatever the size of the job, it’s backed by our one-year guarantee.

External mastic in Cairston: local notes

Cairston is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Island jobs need planning around ferries and the weather, so the more notice, the better.

Managing a site like stromness primary school? Then its movement joints, gutters and trims need looking after like any other building’s.

Do you need external mastic in Cairston?

Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.

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

  • Moss and dirt in joints with no sealant left
  • Gaps where render, brick and frames meet
  • Old sealant gone brittle and cracked
  • Movement joints filled with mortar instead of sealant

In and around Cairston, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

  • How long the guarantee is

Aftercare tips

So the new joints stay in good condition:

  • Keep water from gutters off the wall
  • Get split or bare joints resealed while the damage is small
  • Ask before painting over external sealant
  • Keep movement joints as flexible joints, not mortar

Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.

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.

Why act early in Cairston

Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way and it means sorting access once. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

What happens on the day

Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. Outside jobs in Cairston need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.

  1. We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. Both sides are cleaned back to sound material and primed if needed.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about any water getting in
  • Let us know about earlier repairs to the joints

Different surfaces, different methods

Brickwork movement joints

Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.

Copings and trims

Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.

How we quote for external mastic

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

  • The size of the job
  • Any mould that needs treating
  • How many areas need sealing
  • Access and height

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

What to tell us for a quote

To help us quote quickly, please include:

  • What’s wrong with the joints now
  • If someone has resealed it before
  • Roughly how big the job is
  • Where the property is

For a quote, send an email to info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.

When something else is needed

It helps to know what we can’t do too:

  • Cracking across the wall rather than at a joint
  • Rising or penetrating damp from elsewhere in the wall
  • Movement that’s more than a sealant joint can take

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.

What we seal

  • Brickwork movement joints
  • Copings & trims
