External mastic in Kelvinhaugh, done properly
For buildings in Kelvinhaugh, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on façade panels, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are failed seals between different materials and water getting into walls through failed joints.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. In Kelvinhaugh, work on shared parts of a tenement is generally agreed between owners, often with a factor arranging it.

How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.

External mastic in Kelvinhaugh: local notes
Kelvinhaugh 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Rented homes near Exhibition Centre station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around Sandyford Henderson Memorial Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How the visit works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. Parking in city streets around Kelvinhaugh 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 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.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.

Advice
What we’re called out for in Kelvinhaugh
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Most people get in touch after spotting something like this:
- Movement joints with cracked, split or missing sealant
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
For site and facilities teams at buildings such as Church Street Primary School, its movement joints, gutters and trims need looking after like any other building’s.

FAQs for Kelvinhaugh
Is Kelvinhaugh in your area for external mastic?
Yes. We work across all of Scotland, and Kelvinhaugh is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Who arranges sealant work on the shared parts of a tenement in Kelvinhaugh?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces, primed where needed.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
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 doesn’t stand out.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
When something else is needed
New sealant cannot fix everything, and we’ll tell you before any work starts. It will not solve:
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
- Rising or penetrating damp from elsewhere in the wall
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
