External mastic in Bannockburn, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. If you are dealing with hard, crazed mastic that has stopped moving and rigid filler in a joint that should flex, we can help.
External sealant needs dry surfaces, so outdoor work around Bannockburn is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
You get a one-year guarantee, the same in Bannockburn as everywhere else we work.

Bannockburn questions
Do you work for landlords with property near Stirling station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Will you come out to Bannockburn?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin from the range available.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.

Common problems we fix in Bannockburn
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint.
People usually contact us when they notice something like this:
- Leaking joints around cladding and façade panels
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
Homes close to St Ninian's Roman Catholic Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Quotes for external mastic in Bannockburn
Call for a quick quote. What matters most is:
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows

- How much there is to do

When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before you book.

What external mastic looks like in Bannockburn
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Rented homes near Stirling station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Why deal with it now?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Around Bannockburn, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. Outside jobs in Bannockburn need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
