What external mastic looks like in Sighthill
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 failed outside joints work against that.
For site and facilities teams at buildings such as St. Roch's Secondary School, its movement joints, gutters and trims need looking after like any other building’s. Provand's Lordship, about 0.6 miles south, is one of the historic houses in the wider area around Sighthill, and older homes nearby need a sealant that suits their walls.
Sighthill is about 1 mile east of Woodside, in Glasgow. Sighthill gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Sighthill is one of 183 places in Glasgow where we work.
We cover every part of G21, G4 and G2 for external mastic. External mastic is available to properties on St James Road, Stirling Road and Pinkston Road and the roads around them.

External mastic in Sighthill, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. If you are dealing with joints pointed up with cement by mistake and failed sealant between panels on a façade, we can help.
On a four-storey tenement, gutter joints are a long way from the street, and a slow drip can stain and soak the stone for a long time before it’s spotted. For a building in Sighthill, access is planned first, and shared parts may need the other owners to agree.
Whatever the size of the job, it’s backed by our 12-month guarantee in Sighthill and across Glasgow.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Parking in city streets around Sighthill 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.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Clear the area around the work
- Keep children and pets away from the work area

What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Subsidence or other structural problems
- Render that’s blown, hollow or coming away
- Rising or penetrating damp from elsewhere in the wall
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.
Surfaces we seal
- Copings & trims
- Façade panels
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
Why act early in Sighthill
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Private landlords in Sighthill must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.

Other services in Sighthill
What we’re called out for in Sighthill
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
It’s worth asking for a quote if you see:
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
Rented homes near Barnhill station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What to look for in a quote
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
- The length of the guarantee
- What the quote includes, VAT included or not
Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Make sure movement joints are not pointed over
- Look over the joints every year, ideally after winter
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
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.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
Sighthill: your questions answered
Can you do external mastic in Sighthill?
Yes, Sighthill is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear quote.
How do repairs to the shared parts of a tenement in Sighthill get organised?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t.
What does external mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it does not stand out.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
