DIY sealant or a professional job?
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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
About our external mastic in Milton Bridge
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We are often asked to deal with weeds or debris growing in open joints and joints where the bead has come unstuck, across concrete & block, joints between brick and frames and copings & trims.
External sealant needs dry surfaces, so outdoor work around Milton Bridge is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
There’s a 12-month guarantee on every job.

Honest limits
A few problems are outside what sealant work can do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Loose or hollow render, which needs re-rendering
- Movement that’s more than a sealant joint can take

What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
How long will you be here?
A typical job takes anything from a few hours to several days, depending on the building. Your quote will say how long we expect yours to take.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Looking after it afterwards
So the new joints stay in good condition:
- Get split or bare joints resealed while the damage is small
- Deal with leaking gutters that soak the joints below
- Do not let climbing plants root in the sealant
- Ask before painting over external sealant
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
What happens on the day
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Around Milton Bridge, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Related advice
When to call us in Milton Bridge
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
Keep an eye out for any of the following:
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
- Sealant pulling away from one side of the joint
- Damp patches traced to an open external joint
For an older house near a landmark such as Glencorse Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- What guarantee comes with the work
- How the colour is chosen
- How hidden problems are handled
- Whether all the old sealant comes out first
Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
Milton Bridge buildings and the weather
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Beeslack Community High School, larger buildings have long runs of movement joint that eventually need resealing.
