Glazing silicone in Forton, done properly
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. We work on glass-to-frame joints, rooflights and glass-to-glass joints, and common reasons people get in touch are glass-to-glass joints that have split and leaks from the base of a shower screen.
In smaller places like Forton, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
Each job carries a 12-month guarantee.

Forton homes and the weather
Forton is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to St John the Evangelist include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as St Mary's Catholic Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
Forton is about 1 mile south-east of Gosport, in Hampshire. Jobs in Forton get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Forton is one of 683 towns and villages in Hampshire where we work.

How the job changes by surface
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. When it splits, water can get into the frame.
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.

Why it’s worth doing now in Forton
Replacing windows or a shower screen isn’t needed for a failed joint. Sound glass and frames generally just need resealing. Homes in smaller places like Forton 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.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Avoid scraping close to the bead
- Act on drips or damp patches early
- Wipe the screen down after showering
- Use a gentle glass cleaner and a soft cloth
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we’ll find out which.
How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours, depending on how many joints need doing for a typical job. Parking around Forton is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Advice
Do you need glazing silicone in Forton?
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
- Sealant that was laid over old silicone and failed
- Drips on the inside of a conservatory window
- Glazing silicone that has cracked or come away
For landlords with property near Portsmouth Harbour station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
