About our glazing silicone in St Ibbs
Frameless shower screens rely on sealant to keep water in. Leaks generally come from the wall joint or the tray joint and both get fresh anti-fungal silicone. Typical jobs include sealant that was laid over old silicone and failed and conservatory leaks at frame and glazing joints, across glass-to-frame joints, rooflights and glass balustrade bases.
Somewhere as small as St Ibbs, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee, large or small.

Glazing silicone in St Ibbs: local notes
Historic houses like Knebworth House (about 4.1 miles south-east) are a reminder that the area around St Ibbs has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
In the older streets around Church of St Ippolyts (church of England), the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as St Ippolyts Church of England Aided Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Why act early in St Ibbs
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. Where a wall is exposed, as many are in small places like St Ibbs, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before any work starts.

Advice
Signs you need glazing silicone in St Ibbs
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
The most common problems we see are:
- Cracked silicone between glass panels
- Failed sealant around rooflight glass
- Black or yellowed silicone on glass joints
- A quick top-up bead that didn’t last
For landlords with property near Hitchin station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
Questions to ask before booking
- Are they insured?
- Who turns up on the day
- Is the old sealant removed completely?
- When the joint can take water or movement
When something else is needed
A few problems are outside what sealant work can do:
- Structural problems with a conservatory roof
- Leaks from the roof covering or flashing (a roofer’s job)
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal
- Shower screens
- Glass balustrade bases
- Glass-to-glass joints
- Glass-to-frame joints
- Rooflights
- Conservatory frames
Looking after it afterwards
After the cure time, these simple habits help:
- Get a new leak looked at quickly
- Clear the conservatory gutters regularly
- Avoid scraping close to the bead
- Avoid strong solvents on or near the sealant
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we’ll tell you which.
