External mastic for homes and businesses in Linthouse
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We are often asked to deal with hard, crazed mastic that has stopped moving and rain getting behind render or cladding at a joint, across façade panels, brickwork movement joints and joints between brick and frames.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Linthouse, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
Big or small, you get the same one-year guarantee.

How the job changes by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
What else we do in Linthouse
Do you need external mastic in Linthouse?
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Signs it’s time to call us include:
- Plants rooting in failed movement joints
- Leaking joints around cladding and façade panels
- Water getting into walls through failed joints
- Joints with sealant missing in places
Schools such as Govan High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- The length of the guarantee
- How hidden problems are handled
- How the colour is chosen
- When the joint can take water or movement
FAQs for Linthouse
How is work on the outside of a tenement in Linthouse normally arranged?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Can you help a landlord with a rental near Cardonald station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Are you insured?
Yes. We’re fully insured for every job we do.
Where are you based?
We work from Crawley. Our applicators cover Linthouse, along with the rest of our area.
Is there a guarantee?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
Honest limits
In fairness, some problems need a different trade:
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that’s blown, hollow or coming away
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Parking in city streets around Linthouse can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
- Mention any parking rules near the property

Advice
Outside joints around Linthouse
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Glasgow’s tenements are largely red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it.
If you live in an older home near Linthouse Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Cardonald station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

We quote each job individually. These are the things that affect it:

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

How to look after the new joints
So the new joints stay in good condition:
- Keep high-pressure jets off the joints
- Check the sealant is paintable before painting near it
- Never let anyone fill a movement joint with mortar
- Tell anyone working on the walls about the movement joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
