About our glazing silicone in Old Malden
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. If you have failed sealant around rooflight glass and water escaping where a screen meets the wall, we can put it right.
Around Old Malden, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Whatever the size of the job, it’s backed by our 12-month guarantee in Old Malden and across Surrey.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Surface by surface
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. The bead needs to be tidy and fully bonded.
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.

What glazing silicone looks like in Old Malden
Historic houses like Fitznells Manor (about 1.8 miles south-east) are a reminder that the area around Old Malden has older buildings as well as new. Where a home is older, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Parish Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Knollmead Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Common problems we fix in Old Malden
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
These are the problems we are asked about most:
- Silicone pulling away from the glass
- Leaks from the base of a shower screen
- Black or yellowed silicone on glass joints
- Drips on the inside of a conservatory window
If you let a flat or house near Tolworth station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Before booking anyone
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
- Whether VAT is included
- What guarantee comes with the work
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Avoid scraping close to the bead
- Clear the conservatory gutters regularly
- Use a gentle glass cleaner and a soft cloth
- Keep air moving in the conservatory
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
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.
