Riddrie questions
Can you do external mastic in Riddrie?
Yes, Riddrie 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.
How is work on the outside of a tenement in Riddrie usually arranged?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.
Do you work at height?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What colours does the sealant come in?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
How long will you be here?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we will say how long yours will take.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
External mastic in Riddrie
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. If you are dealing with gaps where render, brick and frames meet and movement joints filled with mortar instead of sealant, we can put it right, on brickwork movement joints, copings & trims and render & cladding joints alike.
Gutters and downpipes on tall city tenements are a long way up, and a slow drip can stain and soak the stone for a long time before it’s spotted. In Riddrie, access needs planning, and work on shared parts may need the other owners’ agreement.
Our work is backed for twelve months, in Riddrie and everywhere else we cover.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What affects the quote in Riddrie
Jobs vary more than people expect. What affects the quote:
- Access and height
- How many areas need sealing
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
Asking for a quote
When you contact us, these details help:
- How many joints, rooms or windows are involved

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Ask before painting over external sealant
- Wash walls gently around the sealant
- Get split or bare joints resealed while the damage is small
- Make sure movement joints are not pointed over
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It normally takes a few hours for a handful of joints, longer for a whole elevation. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Riddrie, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- 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 access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can

When to call us in Riddrie
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
Any of these means the joints need attention:
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
- Old sealant gone brittle and cracked
- Leaking joints around cladding and façade panels
Historic houses such as Provand's Lordship, about 2 miles west, show how far back building around Riddrie goes, and older homes nearby need a sealant that suits their walls.
What your quote should include
- What product goes in the joint
- How long to leave it before use
- Is the old sealant removed completely?
- What happens if they find a problem under the old sealant

What else we do in Riddrie
Why act early in Riddrie
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. For landlords in Riddrie, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Walls and rooflines in Riddrie
Glasgow’s tenements are largely red and blond sandstone, and porous sandstone needs a sealant that will not mark it. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Rented homes near Alexandra Parade station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as St Andrew's Secondary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
