External & façade joints in Whiteinch, Glasgow
External mastic for Whiteinch, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

Common problems we fix in Whiteinch
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.
Signs it’s time to call us include:
- Joints with sealant missing in places
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
Schools such as Ladywell School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

About our external mastic in Whiteinch
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. If you’re dealing with sealant that has lost its bond to the brick or render and rigid filler in a joint that should flex, we can help, on copings & trims, brickwork movement joints and façade panels alike.
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. In Whiteinch, access needs planning, and work on shared parts may need the other owners’ agreement.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

When it is not the sealant
It helps to know what we cannot do:
- Rising or penetrating damp from elsewhere in the wall
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems

Walls and rooflines in Whiteinch
With historic houses such as Tenement House (about 2.5 miles east) nearby, there’s older building stock in the area around Whiteinch as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For landlords with property near Jordanhill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to St Paul's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

How to look after the new joints
Looking after new joints is easy:
- Get split or bare joints resealed while the damage is small
- Keep movement joints as flexible joints, not mortar
- Point out the joints to other trades
- Keep water from gutters off the wall
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What affects the cost of external mastic
Every job gets its own quote. This is what makes a difference:
- The old material and how stubborn it is
- Whether the work is at height
- When we can work, for business premises
- The size of the job
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Before you ask for a quote, have a think about:
- Roughly how big the job is
- Any access issues, like height or stairs
- The type of property
- Where the property is
Getting a quote is simple: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
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 go through it with you.

Your questions about external mastic in Whiteinch
Do you work for landlords with property near Jordanhill station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Can you do external mastic in Whiteinch?
Yes, Whiteinch is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Are you fully insured?
Yes. Mr Mastic is fully insured.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Inside a flat in Whiteinch, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Mention any tricky access
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
