Drumoyne External Mastic
Our applicators work in Drumoyne on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Leaking joints around cladding and façade panels
External mastic in Drumoyne, done properly
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. Typical jobs include sealant that has lost its bond to the brick or render and weathered mastic that no longer stretches, across joints between brick and frames, copings & trims and brickwork movement joints.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. In Drumoyne, those joints dry out over time and let water in behind the render or cladding.
Whatever the size of the job, you get the same 12-month guarantee.

When it is not the sealant
New sealant cannot fix everything, and we’ll tell you before we start. It will not solve:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Façade panels
- Copings & trims
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
Surface by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Point out the joints to other trades
- Check external joints each spring
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Quotes for external mastic in Drumoyne
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- Which sealant suits the joint
- How many areas need sealing
- Any working-time requirements on site

- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Where the property is

What we do, step by step
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Parking in city streets around Drumoyne can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
Getting a quote
Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand, and we will take it from there.
Advice
Common problems we fix in Drumoyne
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Common reasons people contact us include:
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Plants rooting in failed movement joints
If you look after a building such as Govan High School, larger buildings have long runs of movement joint that eventually need resealing.

Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Your title deeds say which parts are shared. Historic houses like Pollok House (about 2 miles south) are a reminder that the area around Drumoyne has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
