External & façade joints in Gilshochill, Glasgow
Our applicators work in Gilshochill on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.

- Leaking joints around cladding and façade panels
- Joints where the bead has come unstuck
How we handle external mastic in Gilshochill
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on joints between brick and frames, render & cladding joints and façade panels, and common reasons people get in touch are rain getting behind render or cladding at a joint and moss and dirt in joints with no sealant left.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. For a tenement in Gilshochill, repairs to shared parts are generally agreed between the owners, often through a property factor.
All our work is covered by a 12-month guarantee.

How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. In a city area like Gilshochill, parking may be by permit or pay-and-display, so tell us what’s nearby. If you’re in a flat, let us know how we get in at the street door.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.

External mastic in Gilshochill: local notes
Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that will not mark it. Gilshochill is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
If you look after a building such as John Paul Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Gilshochill station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
Gilshochill is about 3 miles south-east of Bearsden, in Glasgow. Across the G20 area, we cover external mastic for homes and businesses. Gilshochill is one of 183 towns and villages in Glasgow where we work.
Here we cover the G20, G23 and G22 postcode area for external mastic. Local streets include Cadder Road, Tresta Road and Maryhill Road, all of which we cover. We also cover Cadder (1 mile north-east), High Ruchill (1 mile south), Maryhill (1 mile west), Botany (1 mile south-west) and Lambhill (1 mile east).

Around Gilshochill

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. For landlords in Gilshochill, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Common problems we fix in Gilshochill
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall.

- Cracked joints where brick meets render or frames
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
- Joints pointed up with cement by mistake

Your questions about external mastic in Gilshochill
Who arranges sealant work on the shared parts of a tenement in Gilshochill?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t.
Is Gilshochill in your area for external mastic?
Yes, Gilshochill is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Honest limits
Before you book, it’s worth knowing the limits too:
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.
