Glazing silicone for homes and businesses in Isle of Whithorn
Cracked, stained or lifting silicone on glass looks poor and can leak. It comes off cleanly, without marking the glass and reseal the joint. We’re often asked to deal with rooflight joints letting water in and leaks from the base of a shower screen, across conservatory frames, shower screens and glass balustrade bases.
Mastic can only go onto a dry joint, so outside work in Isle of Whithorn depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Different surfaces, different methods
Shower screens
Frameless screens rely on silicone at the base and wall. We reseal without scratching the glass.
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We use a glazing silicone suited to each.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes anything from an hour or two to most of a day, depending on the size of the job, depending on the size of the job. Around Isle of Whithorn, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- 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.

- Mention any tricky access
- Move anything stored near the joints

Glazing silicone in Isle of Whithorn: local notes
Isle of Whithorn is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on glazing joints and frame seals, especially on the side facing the sea. The west of Scotland is wetter than the east, which means glazing joints and frame seals has to cope with a lot of rain.
Homes close to Isle Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Leave it or put it right?
Replacing windows or a shower screen isn’t needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes, and we’ll tell you if that is not the case. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

- Glass-to-glass joints that have split
