How we handle external mastic in Chartershall
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. Typical jobs include weeds or debris growing in open joints and movement joints filled with mortar instead of sealant, on façade panels, brickwork movement joints and render & cladding joints.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
All our work comes with our 12-month guarantee, wherever you are in Stirling.

Why act early in Chartershall
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Landlord and commercial work in Chartershall
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Do you need external mastic in Chartershall?
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
It’s worth asking for a quote if you see:
- Water getting into walls through failed joints
- Failed sealant between panels on a façade
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
If you let a flat or house near Stirling station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What happens on the day
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Outside jobs in Chartershall need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, the joints are inspected and the access agreed.
- 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.
Getting ready for the visit
- On commercial sites, let us know about site rules

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
- Leave the joints unpainted unless we have said otherwise
- Have failed joints looked at early
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
FAQs for Chartershall
Will you come out to Chartershall?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Stirling station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
How long will you be here?
Most jobs take a few hours to a few days, depending on the length of joint and the access. Your quote will say how long we expect yours to take.
Chartershall buildings and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
