Glazing silicone in Newbridge
We renew glazing silicone on conservatories, 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. We work on conservatory frames, glass-to-glass joints and glass-to-frame joints, and people most often call us about a quick top-up bead that didn’t last and leaking glazing joints on a rooflight.
Homes in small places like Newbridge often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Each job carries a 12-month guarantee.

Why it’s worth doing now in Newbridge
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames normally just need resealing, and we will tell you if that is not the case. Older cottages and farmhouses around Newbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Newbridge: your questions answered
Can you help a landlord with a rental near Ashurst New Forest station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Newbridge in your area for glazing silicone?
Yes, Newbridge is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Which silicone is used for glass joints?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice.
Why not top up the existing silicone?
Many leaks we see come from exactly that. A proper job means cutting out, cleaning and resealing.
Can you replace a misted double-glazed unit?
Glass replacement isn’t our trade. We look after the sealant joints and can tell you if a unit seems to have gone.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you seal glass balustrade bases?
Yes. We cut out the failed sealant and reseal the base joint using a sealant that suits the materials.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- A sagging or failing conservatory roof
- Cracked or broken glass
- Failed flashing around a conservatory
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Signs you need glazing silicone in Newbridge
On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the edges begin to peel.
Signs it’s time to call us include:
- Water getting into a conservatory at the joints
- Sealant that was laid over old silicone and failed
- Silicone pulling away from the glass
- Cracked silicone between glass panels
Managing a site like Copythorne CofE Infant School? Then the mastic around its windows and doors needs looking after like any other building’s.

What glazing silicone looks like in Newbridge
With historic houses such as Landford Manor (about 3.8 miles north-west) nearby, there’s older building stock in the area around Newbridge as well as newer homes. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Ashurst New Forest station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
