External Mastic in Riverside
We cover Riverside for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Brick movement joints where the sealant has split
- Sealant that has lost its bond to the brick or render
- Panel joints letting water in
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Show decorators and builders where the movement joints are
- Deal with leaking gutters that soak the joints below
- Look over the joints every year, ideally after winter
- Keep movement joints as flexible joints, not mortar
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
External mastic in Riverside, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We work on brickwork movement joints, façade panels and render & cladding joints, and people most often call us about panel joints letting water in and movement joints with cracked, split or missing sealant.
In and around a place like Riverside, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What external mastic looks like in Riverside
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Schools such as Wallace High School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Methodist Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

What is a movement joint?
A vertical gap in a long brick wall is normally a movement joint. It gives the wall room to move.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Surface by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’ll tell you before work begins. It will not solve:
- Adding movement joints to masonry that has none
- Subsidence or other structural problems
- Damp that isn’t coming from the joint
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.

Do you need external mastic in Riverside?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Most people get in touch after spotting one of these:
- Panel joints letting water in
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
- Old sealant gone brittle and cracked
For landlords with property near Stirling station, split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include

- Whether they’re fully insured
The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Outside jobs in Riverside need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

Advice
Landlord and commercial work in Riverside
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
