- Conservatory leaks at frame and glazing joints
- Mouldy sealant around glass panels
- Drips on the inside of a conservatory window
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep air moving in the conservatory
- Keep scrapers and blades away from the silicone
- Keep harsh solvents off the silicone
- Act on drips or damp patches early
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Do not leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
Glazing silicone in Long Hanborough
We don’t replace glass, and misting between panes means a failed sealed unit. Our work is the sealant joints, which is where many leaks start. If you have rooflight joints letting water in and mouldy sealant around glass panels, we can put it right, on shower screens, glass-to-glass joints and glass balustrade bases alike.
In smaller places like Long Hanborough, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Each job carries a 12-month guarantee, large or small.

Why act early in Long Hanborough
If the problem is a misted unit or a broken panel, sealant won’t help. We say so plainly, so you can call the right trade. Homes in smaller places like Long Hanborough can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
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. We give a clear quote before any work starts.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, 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.
Common questions in Long Hanborough

How long does the job take?
Most jobs take anything from an hour or two to most of a day, depending on the size of the job, including preparation and clearing up. We will confirm how long when we quote.

What we are called out for in Long Hanborough
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
Keep an eye out for any of the following:

- Stained, discoloured glazing silicone

Advice
What glazing silicone looks like in Long Hanborough
Historic houses like Blenheim Palace (about 1.9 miles north-east) are a reminder that the area around Long Hanborough has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Combe station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For an older house near a landmark such as Christ Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Different surfaces, different methods
Glass balustrade bases
Outdoor balustrade joints face the weather. Renewing the sealant keeps water out of the channel.
Rooflights
Water around a rooflight isn’t always the sealant. We check which it is.
