How we handle glazing silicone in Potters Bar
We don’t replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that is often where the water gets in. If you are dealing with leaks from the base of a shower screen and failed joints on frameless glass, we can put it right.
Potters Bar mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. In every case, the joint between frame and wall is what keeps water out.
Each job carries a 12-month guarantee.

Where are you based?

Different surfaces, different methods
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We use a glazing silicone suited to each.
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. In Potters Bar, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Should I try it myself first?
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 does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Potters Bar homes and the weather
Historic houses like Wyllyotts Manor (about 0.4 miles west) are a reminder that the area around Potters Bar has older buildings as well as new. 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Potters Bar station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Homes close to St. Mary's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common problems we fix in Potters Bar
On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the joint starts to lift.
These are the problems we’re asked about most:
- Failed sealant around rooflight glass
- Mouldy sealant around glass panels
- Failed joints on frameless glass
- Leaks where conservatory glass meets the frame
For site and facilities teams at buildings such as Ladbrooke Junior Mixed and Infant School, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Whether you can choose the colour
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
- Are they insured?
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Do not leave a drip for the next storm
- Look over the glazing joints once a year
- Run a squeegee over the glass when you’re done
- Keep conservatory gutters clear of leaves
Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we will tell you which.
