About our external mastic in Penpont

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 joint does not stand out. If you’re dealing with failed sealant between panels on a façade and hard, crazed mastic that has stopped moving, we can put it right.

Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.

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

Your questions about external mastic in Penpont

Do you cover Penpont for external mastic?

Yes. We work across all of Scotland, and Penpont is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.

Will you come out to Penpont?

Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.

What does external mastic cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.

Do you work at height?

It depends on the building. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.

Is it messy?

No. We protect the surfaces around the joints, and we tidy up before we go.

When will the joints need doing again?

That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.

I rent my home. Can I book you?

Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

Why do you put foam in the joint first?

That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.

What we do, step by step

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. 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 will reach them.
  2. The old mastic and anything lodged in the joint is removed.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Preparing for the visit

  • Mention any parking rules near the property
  • Tell us about any water getting in
  • Mention any sign-in or site rules at work premises

What we are called out for in Penpont

Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.

Signs it’s time to call us include:

  • Sealant that has lost its bond to the brick or render
  • Weathered mastic that no longer stretches
  • Brick movement joints where the sealant has split
  • Rain getting behind render or cladding at a joint

Schools such as Wallace Hall Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Before booking anyone

  • Who does the work, and how experienced they are
  • Whether all the old sealant comes out first
  • How the colour is chosen
  • How hidden problems are handled

10 questions to ask before you book

What external mastic looks like in Penpont

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

If you live in an older home near Penpont Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Quotes for external mastic in Penpont

Some jobs are bigger than they look, and some smaller. What affects the quote:

What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

Leave it or put it right?

A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. 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.

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Honest limits

To be straight with you, some problems need a different trade:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Cracks in the bricks or render themselves, away from the joints
  • Render that’s blown, hollow or coming away

Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Surfaces we seal

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

Surface by surface

Joints between dissimilar materials

Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
