Why act early in Milton Bridge
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Why book with us
- Every job guaranteed for a year
- Any old sealant cut out fully, not covered over
- Tidy, careful work
- Quality sealants from Arbo and Everbuild

Common problems we fix in Milton Bridge
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
The most common problems we see are:
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
- Draughty joints inside around the window
For site and facilities teams at buildings such as Beeslack Community High School, larger buildings have plenty of frames, and the mastic around each one ages.

Different surfaces, different methods
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Window mastic in Milton Bridge: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Homes close to Glencorse Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How to look after the new joints
To keep the joints looking good and working properly:
- Walk round the house once a year and look at the joints
- Keep paint and stain on wooden frames in good order
- Keep paint off silicone joints
- Keep drainage slots and sill grooves clear
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
