Menstrie External Mastic
External mastic across Menstrie and nearby, with old sealant always removed completely.
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
- Sealant that has lost its bond to the brick or render
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
External mastic for homes and businesses in Menstrie
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. Common call-outs are for rigid filler in a joint that should flex and gaps where render, brick and frames meet, across copings & trims, concrete & block and brickwork movement joints.
In and around a place like Menstrie, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
Every job is covered by our 12-month guarantee, wherever you are in Clackmannanshire.

Different surfaces, different methods
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. Outside jobs in Menstrie 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 we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- 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.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

Menstrie questions
Do you work for landlords with property near Alloa station?
Yes, we work for landlords and agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Does the coastal weather in Menstrie affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you guarantee your work?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
When will the joints need doing again?
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. Every job carries our one-year guarantee.
Is there any odour?
Possibly a little. It fades as the sealant cures.
What is a movement joint?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
External mastic in Menstrie: local notes
Menstrie is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Letting a property close to Alloa station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Lornshill Academy, larger buildings have long runs of movement joint that eventually need resealing.

Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. Around Menstrie, water from a failed joint in an older stone home can soak into timber and plaster.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Act on the first splits you see
- Make sure movement joints aren’t pointed over
- Wash walls gently around the sealant
- Keep water from gutters off the wall
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
