External mastic in Halfway, done properly
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it. Typical jobs include gaps where render, brick and frames meet and old sealant gone brittle and cracked, on concrete & block, façade panels and copings & trims.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. Around Halfway, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

Outside joints around Halfway
Halfway 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. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Your title deeds say which parts are shared.
Historic houses such as Pollok House, about 1.3 miles south-east, show how far back building around Halfway goes, and older homes nearby need a sealant that suits their walls. If you let a flat or house near Corkerhill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Halfway is about 2 miles south-west of Yorkhill, in Glasgow. Across the G52 area, we can carry out external mastic at your property. Halfway is one of 183 towns and villages in Glasgow we cover for external mastic.

How do repairs to the shared parts of a tenement in Halfway get organised?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
When is the sealant fully cured?
It depends on the product. Before we leave, we’ll tell you the cure time.

What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Why it’s worth doing now in Halfway
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. 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.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- Quality sealants from Arbo and Everbuild
- We never seal over old sealant
- Every job guaranteed for a year
- Anti-fungal sanitary silicone in wet areas

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Asking for a quote
To help us quote quickly, let us know:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Any access issues, like height or stairs

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, send an email to info@mrmastic.co.uk.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid pressure-washing directly into sealant joints
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
Do you need external mastic in Halfway?
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
- Movement joints filled with mortar instead of sealant
If you look after a building such as Craigton Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Before you book anyone
- What product goes in the joint
- What preparation is included
- How long to leave it before use
- Is VAT in the price?
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a handful of joints, longer for a whole elevation. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Halfway, it helps to know the floor, the door entry arrangements and the nearest parking.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
