Your questions about glazing silicone in Cottered
Do you cover Cottered for glazing silicone?
Yes. Our work covers London and the South East, and Cottered is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Cottered?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
What does glazing silicone cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Do you reseal glass shower screens?
Yes, we do these often. We use anti-fungal silicone made for wet areas.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Glazing silicone for homes and businesses in Cottered
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. Common call-outs are for sealant that was laid over old silicone and failed and drips on the inside of a conservatory window, across shower screens, rooflights and conservatory frames.
Homes in small places like Cottered often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Do you need glazing silicone in Cottered?
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
Signs it’s time to call us include:
- Conservatory leaks at frame and glazing joints
- Shower screens leaking along the wall or tray
- A quick top-up bead that didn’t last
- Cracked silicone between glass panels
For an older house near a landmark such as Parish Church of St John the Baptist, the joint between an old wall and a newer frame is generally the first place rain gets in.

Leave it or put it right?
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. In a small place like Cottered, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What glazing silicone looks like in Cottered
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Freman College, larger buildings have plenty of frames, and the mastic around each one ages.

How the job changes by surface
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Get a new leak looked at quickly
- Squeegee the shower screen after each use
- Avoid scraping close to the bead
- Keep conservatory gutters clear of leaves
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most jobs and we leave things clean and tidy. Somewhere as small as Cottered, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Let us know about earlier repairs to the joints
