Ashampstead Glazing Silicone
Our applicators work in Ashampstead on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Split or lifting silicone on glass
- A quick top-up bead that didn’t last
- Water running down inside the glass
Why it’s worth doing now in Ashampstead
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before you notice. Around Ashampstead, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email and we’ll talk you through it.

About our glazing silicone in Ashampstead
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. We work on glass-to-glass joints, rooflights and glass balustrade bases, and the jobs we see most are leaks from the base of a shower screen and conservatory leaks at frame and glazing joints.
Mastic can only go onto a dry, clean joint, so window work in Ashampstead is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Do you need glazing silicone in Ashampstead?
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip on the glass.
These are the problems we’re asked about most:
- Conservatory leaks at frame and glazing joints
- Shower screens leaking along the wall or tray
- Stained, discoloured glazing silicone
- Silicone pulling away from the glass
For an older house near a landmark such as Church of St Clement, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before booking
- How long the guarantee is
- Whether they’re fully insured
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are
Looking after it afterwards
To keep the joints looking good and working properly:
- Clean glass with a mild cleaner and a soft cloth
- Open vents or windows to let moisture out
- Don’t use a blade near the sealant
- Avoid strong solvents on or near the sealant
On shower screens, wipe or squeegee after use and keep the room ventilated. It helps stop mould getting into the silicone.
A small conservatory leak soon spreads. Water travels along the frame and into the wall so it’s best dealt with right away.
What the job involves on each surface
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Condensation trapped between two panes
- Cracked or broken glass
- Failed flashing around a conservatory
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before you book.
Surfaces we seal
- Rooflights
- Shower screens
- Glass-to-glass joints
- Glass balustrade bases
- Conservatory frames
- Glass-to-frame joints
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to most of a day, depending on the size of the job. In a small place like Ashampstead, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints

Advice
Windows and doors in Ashampstead
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. Historic houses like Basildon Park (about 2.9 miles east) are a reminder that the area around Ashampstead 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.
Rented homes near Goring & Streatley station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
