How we handle glazing silicone in Uppend
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. Typical jobs include drips on the inside of a conservatory window and rooflight joints letting water in, across shower screens, glass-to-glass joints and rooflights.
Around Uppend, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What glazing silicone looks like in Uppend
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Much Hadham Palace (about 4.7 miles south-west) are a reminder that the area around Uppend has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Stansted Mountfitchet station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For site and facilities teams at buildings such as Farnham Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

When to call us in Uppend
New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out leaving a path for water.
Keep an eye out for any of the following:
- Failed sealant around rooflight glass
- Shower screens leaking along the wall or tray
- Black or yellowed silicone on glass joints
- A quick top-up bead that didn’t last
If you live in an older home near Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Which colour the sealant will be
- When the joint can take water or movement
- How hidden problems are handled
- How long the guarantee is
Different surfaces, different methods
Glass balustrade bases
The base joint is cut out and resealed. We don’t install or replace glass.
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
Why it’s worth doing now in Uppend
A new conservatory roof is a big job. If the leak is a failed sealant joint renewing the joint is the simpler fix. If the roof is the problem, we will say so. In a small place like Uppend, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Before we arrive

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Get a new leak looked at quickly
- Keep scrapers and blades away from the silicone
- Clean glass with a mild cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.
