External mastic in Shieldhill, done properly
For buildings in Shieldhill, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Typical jobs include rigid filler in a joint that should flex and gaps where render, brick and frames meet, across render & cladding joints, concrete & block and copings & trims.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

Different surfaces, different methods
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before the bead.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
How the visit works
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Clear the area around the work
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

Advice
FAQs for Shieldhill
I let a flat near Falkirk High station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover Shieldhill for external mastic?
Yes, Shieldhill is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so it doesn’t stand out.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Have failed joints looked at early
- Look over the joints every year, ideally after winter
- Leave the joints unpainted unless we’ve said otherwise
- Clear growth from the base of walls and joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

When to call us in Shieldhill
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
Keep an eye out for these signs:
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
If you let a flat or house near Falkirk High station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why act early in Shieldhill
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start.
Why book with us
- Homes, businesses and hotels
- An ARBOMaster approved applicator

External mastic in Shieldhill: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Schools such as Graeme High School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
