How we handle external mastic in Scotstounhill
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. Typical jobs include joints pointed up with cement by mistake and sealant that has lost its bond to the brick or render, across copings & trims, brickwork movement joints and joints between brick and frames.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. In Scotstounhill, work on shared parts of a tenement is usually agreed between owners, often with a factor arranging it.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

How the visit works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. The work usually takes a few hours for a handful of joints, longer for a whole elevation. Parking in city streets around Scotstounhill 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.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Mention any tricky access

Why act early in Scotstounhill
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a tenement flat in Scotstounhill, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What you get with us
- Domestic, commercial and hotel work
- Full insurance on every job
- A 12-month guarantee on all work
- Sanitary silicone with an anti-fungal additive in wet areas

Aftercare tips
A little care helps the new joints last. Our advice:
- Leave the joints unpainted unless we have said otherwise
- Look over the joints every year, ideally after winter
- Point out the joints to other trades
- Never let anyone fill a movement joint with 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.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
Outside joints around Scotstounhill
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Jordanhill College, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near St David's Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Scotstounhill: your questions answered
I let a flat near Scotstounhill station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
How is work on the outside of a tenement in Scotstounhill generally arranged?
It normally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, large or small.
Do you need external mastic in Scotstounhill?
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
People normally contact us when they notice one of these:
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
- Joints pointed up with cement by mistake
If you let a flat or house near Scotstounhill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Surface by surface
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant is not too deep.
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
