- Hard, crazed mastic that has stopped moving
About our external mastic in Lilybank
External mastic is a job where short cuts show quickly. 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 rain getting behind render or cladding at a joint and leaking joints around cladding and façade panels, across joints between brick and frames, façade panels and brickwork movement joints.
On a four-storey tenement, gutter joints are a long way from the street, and a slow drip can stain and soak the stone for a long time before it’s spotted. In Lilybank, access needs planning, and work on shared parts may need the other owners’ agreement.
Whatever the size of the job, it’s backed by our 12-month guarantee.

The process
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building in most cases. For a tenement in Lilybank, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- 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.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

When to call us in Lilybank
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Any of these means the joints need attention:
- Weeds or debris growing in open joints
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Failed seals between different materials
For landlords with property near Carntyne station, split movement joints are easy to miss on a rental until damp shows inside.

Questions from Lilybank
Is Lilybank in your area for external mastic?
Yes, Lilybank is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
How is work on the outside of a tenement in Lilybank generally arranged?
It generally 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 don’t.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
What colours does the sealant come in?
The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Failed render or damaged cladding panels
- Rising or penetrating damp from elsewhere in the wall
- Movement that’s more than a sealant joint can take
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before booking.
Where we work in Lilybank
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints
- Copings & trims
- Façade panels
- Concrete & block
Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap.
What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. For landlords in Lilybank, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
Why book with us
- We’re fully insured
- Any old sealant cut out fully, not covered over
- Every job guaranteed for a year
- Approved under the ARBOMaster scheme

What external mastic looks like in Lilybank
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, often through a property factor. The title deeds set out which parts are common. With historic houses such as Provand's Lordship (about 2.1 miles north-west) nearby, there’s older building stock in the area around Lilybank as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as Cardinal Winning Secondary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Historic houses such as Provand's Lordship, about 2.1 miles north-west, show how far back building around Lilybank goes.
