About our glazing silicone in Greenock
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. We are often asked to deal with mouldy sealant around glass panels and sealant that was laid over old silicone and failed, on conservatory frames, glass balustrade bases and rooflights.
Scottish weather is hard on window mastic, and a town like Greenock gets its share of wind and rain. The windows facing the weather are usually the first to leak, so it’s worth checking them all.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Get a new leak looked at quickly
- Keep air moving in the conservatory
- Do not use a blade near the sealant
- Check the gutters above the glazing for debris
Keep conservatory gutters clear, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Conservatory leaks rarely stay small. Water runs along frames and down walls, so get it looked at when you first see it.
What we do, step by step
We keep the work tidy and contained to the joints we are treating. The job generally takes anything from an hour or two to most of a day, depending on the size of the job, and we explain the cure time before we leave. Parking around Greenock is rarely difficult, though older streets in the centre can be tight. If you’re in a flat with a shared stair or a door entry system, let us know when you book.
- We find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit

Greenock homes and the weather
Greenock is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Schools such as Wellington Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Drumfrochar station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

DIY versus a professional finish
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 fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Do you need glazing silicone in Greenock?
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.
It’s worth asking for a quote if you see:
- A quick top-up bead that didn’t last
- Mouldy sealant around glass panels
- Water running down inside the glass
- Water escaping where a screen meets the wall
