Glazing silicone in Four Marks, done properly
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. We work on glass-to-frame joints, rooflights and shower screens, and common reasons people get in touch are mouldy sealant around glass panels and drips on the inside of a conservatory window.
Around Four Marks, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Big or small, you get the same one-year guarantee in Four Marks and across Hampshire.

What happens if it’s left?
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames usually just need resealing. Around Four Marks, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What else we do in Four Marks
Surface by surface
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We renew it with a clear or matching glazing silicone.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Looking after it afterwards
So the new joints stay in good condition:
- Wipe the screen down after showering
- Open vents or windows to let moisture out
- Use gentle products around the joints
- Check the gutters above the glazing for debris
On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.
What glazing silicone looks like in Four Marks
With historic houses such as Bentworth Hall (about 2.7 miles north) nearby, there’s older building stock in the area around Four Marks as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of the Good Shepherd, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Four Marks Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Alton station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
