About our glazing silicone in Farnborough
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. Common call-outs are for conservatory leaks at frame and glazing joints and failed sealant around rooflight glass, on glass-to-glass joints, glass-to-frame joints and conservatory frames.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Farnborough.
Every job is covered by our 12-month guarantee.

Surface by surface
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. It must be clean, neat and well bonded.
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We use a glazing silicone suited to each.
The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many joints need doing. For a job in Farnborough, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Before we arrive
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

Frames and glazing around Farnborough
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Down House (about 2.1 miles south-west) are a reminder that the area around Farnborough 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.
If you let a flat or house near Orpington station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. As a London address, Farnborough can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near Church of St Giles the Abbot, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why deal with it now?
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Common questions in Farnborough
Can you help a landlord with a rental near Orpington station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Can parking be tricky for a visit in Farnborough?
Parking in Farnborough, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you reseal glass shower screens?
Yes. The old bead comes off without marking the glass, and the joints are cleaned and resealed.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What does glazing silicone cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Aftercare tips
To keep the joints looking good and working properly:
- Open vents or windows to let moisture out
- Stick to mild cleaners on glass
- Check the silicone on glass every year or so
- Run a squeegee over the glass when you are done
Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.
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.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
