External mastic in Kelvinbridge
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We are often asked to deal with failed seals between different materials and damp patches traced to an open external joint, across copings & trims, façade panels and brickwork movement joints.
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. For a building in Kelvinbridge, access is planned first, and shared parts may need the other owners to agree.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
When to call us in Kelvinbridge
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.
People normally contact us when they notice one of these:
- Old sealant gone brittle and cracked
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
- Panel joints letting water in
For landlords with property near Charing Cross (Glasgow) station, split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before booking
- Whether VAT is included
- What insurance they hold
- What the cure time is
- How long the guarantee is
Looking after it afterwards
To keep the joints looking good and working properly:
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
- Keep soil, plants and ivy away from the joints
- Fix overflowing gutters above sealed joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
Why it’s worth doing now in Kelvinbridge
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost, so the damage spreads beyond the joint. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

External mastic in Kelvinbridge: local notes
Kelvinbridge 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. Historic houses like Tenement House (about 0.6 miles south-east) are a reminder that the area around Kelvinbridge has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as College of Piping are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. In the older streets around St Vincent Street Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on the building in most cases. Parking in city streets around Kelvinbridge can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Let us know about earlier repairs to the joints
- Mention any tricky access
- Move anything stored near the joints
