Mid Calder Glazing Silicone
Glazing silicone across Mid Calder and nearby, with old sealant always removed completely.
- Rooflight joints letting water in
- Water escaping where a screen meets the wall
- Water getting into a conservatory at the joints
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How we handle glazing silicone in Mid Calder
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. If you’re dealing with leaking glazing joints on a rooflight and shower screens leaking along the wall or tray, we can put it right, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Every job comes with a 12-month guarantee, wherever you are in West Lothian.

What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours, depending on how many joints need doing. Somewhere like Mid Calder may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.

Leave it or put it right?
A quick bead over the old sealant might stop a drip for a while, but new silicone won’t bond to old, and the leak generally returns. A proper reseal is the lasting answer. 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.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

- Sealant that was laid over old silicone and failed
- Failed joints on frameless glass
- Black or yellowed silicone on glass joints
- Failed sealant around rooflight glass
Managing a site like Inveralmond Community High School? Then the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before you book
- How the colour is chosen
- What product goes in the joint
- Whether they seal over old material or remove it
- When the joint can take water or movement
What the job involves on each surface
Rooflights
Water around a rooflight isn’t always the sealant. We check which it is.
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep conservatory gutters clear of leaves
- Stick to mild cleaners on glass
- Get a new leak looked at quickly
- Keep harsh solvents off the silicone
Check the joints once a year. Catching a split early keeps the repair small, before water gets in.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below before you spot it.
What glazing silicone looks like in Mid Calder
With historic houses such as Howden House (about 1.4 miles west) nearby, there’s older building stock in the area around Mid Calder as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For an older house near a landmark such as Mid Calder Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Livingston South station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
