Glazing silicone for homes and businesses in Caversham
We work across Caversham on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. Common call-outs are for leaks where conservatory glass meets the frame and water tracking down the inner face of the glass, across rooflights, shower screens and glass-to-frame joints.
Around Caversham, many houses have gained conservatories, French doors or replacement windows over time. Each one adds more joints to look after, and those joints age at different rates. Leaks generally start at a sill, a frame head or a glazing joint.
Our work is backed for twelve months.

When to call us in Caversham
New silicone over old silicone won’t bond. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
It’s worth asking for a quote if you see:
- Water running down inside the glass
- New silicone smeared over old sealant
- Glass-to-glass joints that have split
- Water escaping where a screen meets the wall
For landlords with property near Reading station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Frames that have decayed or split
- A sealed unit that has misted inside
- Cracked or broken glass
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.

If the job is outside, mention gates, side access and anything above ground floor.

Windows and doors in Caversham
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Mapledurham House (about 3 miles west) nearby, there’s older building stock in the area around Caversham 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.
In the older streets around Grace Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like The Hill Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Leave it or put it right?
If the problem is a misted unit or a broken panel, sealant will not help. We say so plainly and point you to a glazier or roofer. Black mould and gaps in sealant don’t fix themselves, and in a busy household in Caversham they spread with every shower and every downpour. Now is the easy time to put it right.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Keeping the joints in good condition
So the new joints stay in good condition:
- Avoid scraping close to the bead
- Stick to mild cleaners on glass
- Act on drips or damp patches early
- Wipe the screen down after showering
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
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.
How the job changes by surface
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. When it splits, water can get into the frame.
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
