External mastic across Pencaitland and nearby, with every bit of old sealant taken out first and a 12-month guarantee.

  • Rain getting behind render or cladding at a joint

External mastic for Pencaitland homes and businesses

Different surfaces, different methods

Render joints

The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.

Concrete and blockwork

Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.

External mastic for homes and businesses in Pencaitland

Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. If you have weathered mastic that no longer stretches and joints where the bead has come unstuck, we can put it right, on copings & trims, façade panels and joints between brick and frames alike.

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

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Your questions about external mastic in Pencaitland

Do you cover smaller places like Pencaitland?

Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.

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

Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.

What is a movement joint?

It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.

Do you use backing rod?

Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.

Will it make a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

How long does the job take?

Typically it takes a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we will tell you how long to expect.

Will there be a smell?

That depends on the sealant. Some products have a noticeable smell, others very little.

Will the old sealant be removed?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

What happens if it’s left?

Sealing over the top of old mastic doesn’t hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. In a place like Pencaitland, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

How we quote for external mastic

Call for a quick quote. The main things that affect it are:

  • The size of the job
  • The old material and how stubborn it is
  • Which sealant suits the joint
  • Any mould that needs treating

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

What to tell us for a quote

To make quoting easier, please include:

  • If someone has resealed it before
  • The problem you’ve noticed
  • Whether it’s a home or a business
  • How many joints, rooms or windows are involved

If you’re in Pencaitland and need external mastic, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

What we do, step by step

Once we are on site, we check the joints match what you told us. 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. For a place like Pencaitland, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. We start by walking round the building and agreeing the joints and the access.
  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. The exterior sealant is applied, tooled and checked along its length.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Mention if the joints have been sealed before
  • Mention any leaks or damp you’ve noticed

Honest limits

New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant will not put right:

  • 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
  • Render that is blown, hollow or coming away

If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.

What we seal

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

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

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.

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.
