Glazing & conservatory sealant in Downside, Surrey
Glazing silicone across Downside and nearby, with old sealant always removed completely.
- Water running down inside the glass
- Water escaping where a screen meets the wall
- Conservatory leaks at frame and glazing joints
Glazing silicone in Downside, done properly
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-frame joints, shower screens and rooflights, and the jobs we see most are water escaping where a screen meets the wall and leaks where conservatory glass meets the frame.
In a village or hamlet like Downside, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
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.

Signs you need glazing silicone in Downside
Not every leak is a sealant problem: broken panels, roof problems and blocked gutters can all let water in. That’s why we trace the leak first.
Keep an eye out for any of the following:
- Conservatory leaks at frame and glazing joints
- Black or yellowed silicone on glass joints
- A quick top-up bead that didn’t last
- Drips on the inside of a conservatory window
Managing a site like St Matthew's CofE Aided Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many areas need sealing
- The product the joint needs
- The number and length of the joints
- Any mould that needs treating
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Whether it’s a home or a business
- Where the job is, and your postcode
- A few photos by email, if you can
- Roughly how big the job is
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Windows and doors in Downside
Historic houses like Byfleet Manor (about 2.7 miles north-west) are a reminder that the area around Downside 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 is traditional sand mastic. 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.
Letting a property close to Cobham & Stoke Dabernon station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Homes close to St Michael's Chapel include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Downside
Is Downside within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Cobham & Stoke Dabernon station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
Do you reseal glass shower screens?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
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.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
Will resealing stop my conservatory leaking?
In many cases, as long as sealant is the cause. We find where the water gets in first before any sealing.
How to look after the new joints
So the new joints stay in good condition:
- Get a new leak looked at quickly
- Look over the glazing joints once a year
- Avoid scraping close to the bead
- Clear the conservatory gutters regularly
Squeegee a shower screen after each shower 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 will tell you which.
