Do you need external mastic in Bridgeton?
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.
These are the problems we are asked about most:
- Joints pointed up with cement by mistake
- Sealant pulling away from one side of the joint
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
Letting a property close to Bridgeton station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before booking
- Which colour the sealant will be
- The length of the guarantee
- What product goes in the joint
- What happens if they find a problem under the old sealant
How we handle external mastic in Bridgeton
For buildings in Bridgeton, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on copings & trims, joints between brick and frames and concrete & block, and the jobs we see most are weathered mastic that no longer stretches and movement joints filled with mortar instead of sealant.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. In Bridgeton, those joints dry out over time and let water in behind the render or cladding.
There’s a 12-month guarantee on every job.

Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Wind-driven rain gets into any failed joint on the outside of a city building, and in Bridgeton, damp can spread through stone and plaster before anyone sees it.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Questions from Bridgeton
I let a flat near Bridgeton station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Bridgeton?
Shared parts of a tenement, such as the roof and outside walls, are normally repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Your title deeds will say who owns the windows.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Bridgeton and the rest of Glasgow, along with the rest of our area.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Outside joints around Bridgeton
With historic houses such as Provand's Lordship (about 1 mile north-west) nearby, there’s older building stock in the area around Bridgeton as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
For site and facilities teams at buildings such as St Mungo's Academy, larger buildings have long runs of movement joint that eventually need resealing. Provand's Lordship, about 1 mile north-west, is one of the historic houses in the wider area around Bridgeton, and older homes nearby need a sealant that suits their walls.

How the job changes by surface
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind.
