About our glazing silicone in Middlegreen
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. We remove it without scratching the glass or frame and reseal the joint. Typical jobs include leaks where conservatory glass meets the frame and glazing silicone that has cracked or come away, on shower screens, glass-to-glass joints and rooflights.
Somewhere as small as Middlegreen, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What glazing silicone looks like in Middlegreen
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 Windsor Castle (about 2.8 miles south-west) are a reminder that the area around Middlegreen 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.
For landlords with property near Langley station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. In the older streets around St Mary the Virgin Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like The Langley Academy Primary? Then larger buildings have plenty of frames, and the mastic around each one ages.

Why it’s worth doing now in Middlegreen
If the problem is a misted unit or a broken panel, sealant will not help. We’ll tell you that rather than seal it anyway, so you can call the right trade. Around Middlegreen, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why book with us
- One-year guarantee on every job

What affects the cost of glazing silicone
Your quote is based on your job. We take into account:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Access and height
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- The rough size of the job
- Photos by email, if that is easy
- Any access issues, like height or stairs
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, ring 0345 464 0079 or drop us an email.
What we cannot put right
New sealant cannot fix everything, and we’ll tell you before we start. Sealant won’t put right:
- A frame that needs repairing or replacing
- Condensation trapped between two panes
- Cracked or broken glass
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Glass-to-glass joints
- Glass balustrade bases
- Glass-to-frame joints
- Conservatory frames
- Shower screens
- Rooflights
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What the job involves on each surface
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
Glass balustrade bases
Glass balustrades sit in a channel that’s often finished with sealant. When it fails, water can sit in the channel.
