Glazing silicone for homes and businesses in Long Ditton
Glazing silicone is a maintenance item. Sun, rain and movement wear it down and cracked joints let water in. Resealing puts that right. We’re often asked to deal with cracked silicone between glass panels and failed sealant around rooflight glass, across glass-to-frame joints, glass balustrade bases and conservatory frames.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the job changes by surface
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. When it splits, water can get into the frame.
Conservatory frames
Conservatory frame joints are a common source of leaks. We cut out the old sealant and reseal.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most jobs, and the area is left clean. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Long Ditton. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Run a squeegee over the glass when you’re done
- Clean glass with a mild cleaner and a soft cloth
- Get a new leak looked at quickly
- Do not use a blade near the sealant
Squeegee a shower screen after each shower and let the room air. It helps stop mould getting into the silicone.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we will tell you which.
Frames and glazing around Long Ditton
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. Historic houses like Hampton Court Palace (about 1.5 miles north-west) are a reminder that the area around Long Ditton 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.
Rented homes near Surbiton station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- Water tracking down the inner face of the glass

Schools such as Long Ditton Infant and Nursery School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
