Todd's Green Glazing Silicone
We cover Todd's Green for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Split or lifting silicone on glass
- Rooflight joints letting water in
- Sealant that was laid over old silicone and failed
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How we handle glazing silicone in Todd's Green
Glass and frames expand and contract differently, and the silicone between them takes the strain. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. We work on shower screens, conservatory frames and glass-to-frame joints, and people most often call us about water tracking down the inner face of the glass and black or yellowed silicone on glass joints.
In a village or hamlet like Todd's Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Glazing silicone in Todd's Green: local notes
With historic houses such as Knebworth House (about 3.5 miles south) nearby, there’s older building stock in the area around Todd's Green as well as newer homes. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as The John Henry Newman School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Mary the Virgin include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Aftercare tips
So the new joints stay in good condition:
- Use a gentle glass cleaner and a soft cloth
- Check the silicone on glass every year or so
- Keep conservatory gutters clear of leaves
- Keep air moving in the conservatory
Gentle products are best near the sealant. Strong solvents can soften or mark it.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
Why act early in Todd's Green
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames usually just need resealing. Older cottages and farmhouses around Todd's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
