Glazing silicone for homes and businesses in Itchen
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. Typical jobs include black or yellowed silicone on glass joints and drips on the inside of a conservatory window, on glass-to-frame joints, shower screens and glass-to-glass joints.
Homes around Itchen range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
There’s a 12-month guarantee on every job, whatever its size.

Why act early in Itchen
Replacing a conservatory roof is major work. If the leak is a failed sealant joint, resealing is far simpler. If it’s the roof itself, we’ll tell you. Homes in smaller places like Itchen can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before work begins.

Different surfaces, different methods
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
Rooflights
Rooflight leaks can come from the sealant or the roof. We check which it is.
Do you need glazing silicone in Itchen?
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. That’s why we trace the leak first.
It’s worth asking for a quote if you see:
- Leaking glazing joints on a rooflight
- Leaks where conservatory glass meets the frame
- Split or lifting silicone on glass
- Black or yellowed silicone on glass joints
For landlords with property near Woolston station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Windows and doors in Itchen
Itchen 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. With historic houses such as Medieval Merchant's House (about 1.5 miles west) nearby, there’s older building stock in the area around Itchen as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Ludlow Junior School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Jesus Chapel - St Mary Extra, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The product the joint needs
- Any mould that needs treating
- Any working-time requirements on site
- How many areas need sealing
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Helping us quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- The address or postcode of the job
- How many joints, rooms or windows are involved
- The problem you’ve noticed
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or email us.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Use gentle products around the joints
- Act on drips or damp patches early
- Look over the glazing joints once a year
- Clear the conservatory gutters regularly
Keep the new joints dry for as long as we advise so the silicone can set properly. After that, clean glass with a mild cleaner.
Do not leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the problem grows.
