Glazing silicone in Ley Green
Sealant on glazing does not last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. We are often asked to deal with drips on the inside of a conservatory window and failed joints on frameless glass, across shower screens, glass-to-frame joints and glass-to-glass joints.
Mastic can only go onto a dry, clean joint, so window work in Ley Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee.

How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours, depending on how many joints need doing. In a small place like Ley Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
How to prepare
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What we’re called out for in Ley Green
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip on the glass.
If you can see any of these, it’s time to have the joints looked at:
- Split or lifting silicone on glass
- Failed sealant around rooflight glass
- Failed joints on frameless glass
- Black or yellowed silicone on glass joints
For an older house near a landmark such as Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Do I need to be at home?

Ley Green homes and the weather
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. With historic houses such as Knebworth House (about 4.9 miles south-east) nearby, there’s older building stock in the area around Ley Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Hitchin station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. If you look after a building such as Preston Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What else we do in Ley Green
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Open vents or windows to let moisture out
- Wipe the screen down after showering
- Stick to mild cleaners on glass
- Keep scrapers and blades away from the silicone
Check the joints once a year. Catching a split early keeps the repair small.
A small conservatory leak soon spreads. Water travels along the frame and into the wall so it’s best dealt with right away.
