About our glazing silicone in Neilston
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. We work on conservatory frames, rooflights and glass-to-glass joints, and the jobs we see most are failed sealant around rooflight glass and glazing silicone that has cracked or come away.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Do you need glazing silicone in Neilston?
New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
Signs it’s time to call us include:
- Water escaping where a screen meets the wall
- Failed joints on frameless glass
- Leaking glazing joints on a rooflight
- Silicone pulling away from the glass
If you live in an older home near Neilston Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

What happens if it’s left?
A quick bead over the old sealant might stop a drip for a while, but new silicone will not bond to old, and the leak generally returns. Cutting out and resealing properly lasts. 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.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We cut it out and start again.
How we quote for glazing silicone
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- The number and length of the joints

The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

Glazing silicone in Neilston: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you look after a building such as St Thomas's School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Neilston station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes anything from an hour or two to most of a day, depending on the size of the job. Outdoor work around Neilston depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
