External mastic in Sandyhills, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. If you have hard, crazed mastic that has stopped moving and sealant that has lost its bond to the brick or render, we can help.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. In Sandyhills, access needs planning, and work on shared parts may need the other owners’ agreement.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Different surfaces, different methods
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours to a few days, depending on the length of joint and the access. Parking in city streets around Sandyhills can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks

Sandyhills: your questions answered
How do repairs to the shared parts of a tenement in Sandyhills get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Can you help a landlord with a rental near Shettleston station?
Yes, we work for landlords and letting agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Outside joints around Sandyhills
Sandyhills is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Historic houses such as Provand's Lordship, about 3.5 miles west, show how far back building around Sandyhills goes. For landlords with property near Shettleston station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Eastbank Academy? Then larger buildings have long runs of movement joint that eventually need resealing.

What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- Loose or hollow render, which needs re-rendering
- Cracked brickwork or render that needs a builder or plasterer
- 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 will tell you honestly.
Surfaces we seal
- Façade panels
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Joints between brick and frames
- Copings & trims
Why it’s worth doing now in Sandyhills
Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a tenement flat in Sandyhills, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What you get with us
- White, clear, grey or coloured to suit, where the product allows
- We never seal over old sealant
- We agree the colour with you first
- An ARBOMaster approved applicator

Should I try it myself first?
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 does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Aftercare tips
A little care helps the new joints last. We recommend:
- Keep water from gutters off the wall
- Ask before painting over external sealant
- Show decorators and builders where the movement joints are
- Don’t let climbing plants root in the sealant
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
