About our window mastic in Bantaskin
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on uPVC windows, patio & French doors and composite doors, and people most often call us about draughts coming in around windows and doors and hard, cracked sealant around windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
- Wipe condensation off the frames
- Keep timber frames painted
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Rotten timber, which needs a joiner first
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Frames and glazing around Bantaskin
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
If you look after a building such as Falkirk High School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Falkirk High station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

When to call us in Bantaskin
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
People generally contact us after spotting one of these:
- Whistling draughts around closed windows
- Water coming in at the bottom corners of a door
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
In the older streets around Falkirk, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- How the colour is chosen
- Is the old sealant removed completely?
- How much experience the applicator has
- When the joint can take water or movement
Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
