Glazing & conservatory sealant in Great Offley, Hertfordshire
Glazing silicone across Great Offley and nearby, with every bit of old sealant taken out first.
- Conservatory leaks at frame and glazing joints
- Shower screens leaking along the wall or tray
- Water running down inside the glass
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Do not use a blade near the sealant
- Keep air moving in the conservatory
- Keep harsh solvents off the silicone
- Check the gutters above the glazing for debris
Check the joints once a year. Spotting a crack early means a simpler fix, before water gets in.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.
How we handle glazing silicone in Great Offley
Sealant on glazing doesn’t last for ever. Weather and movement take their toll and cracked joints let water in. Renewing it keeps glazing joints doing their job. Common call-outs are for stained, discoloured glazing silicone and water escaping where a screen meets the wall, on shower screens, glass-to-frame joints and conservatory frames.
Homes in small places like Great Offley often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Leave it or put it right?

The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

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 doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
