Glazing silicone for homes and businesses in Westerham
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. We work on glass-to-frame joints, shower screens and conservatory frames, and common reasons people get in touch are shower screens leaking along the wall or tray and glazing silicone that has cracked or come away.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
Your job is guaranteed for a year, as with all our work.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from an hour or two to most of a day, depending on the size of the job. In Westerham, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Before we arrive
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints

Related advice
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Do not leave a drip for the next storm
- Look over the glazing joints once a year
- Avoid scraping close to the bead
- Open vents or windows to let moisture out
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part, and we’ll tell you which.
Questions from Westerham
Is Westerham in your area for glazing silicone?
Yes, Westerham is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Is parking a problem for a job in Westerham?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.
Can you reseal the base of a glass balustrade?
Yes. The sealant joint at the base can be renewed. We do not install or replace the glass.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Do you reseal glass shower screens?
Yes. We remove the old silicone carefully before cleaning and resealing.

Westerham homes and the weather
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. With historic houses such as Quebec House (about 0.2 miles south-east) nearby, there’s older building stock in the area around Westerham 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.
Letting a property close to Hurst Green station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For an older house near a landmark such as Church of St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Signs you need glazing silicone in Westerham
Using a sealant not made for glass causes many failures. Some products don’t bond well to glass, and acetoxy types can attack some frame materials.
These are the problems we’re asked about most:
- Leaks from the base of a shower screen
- Sealant that was laid over old silicone and failed
- Split or lifting silicone on glass
- Stained, discoloured glazing silicone
Westerham is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before booking
- Are they insured?
- Which sealant they’ll use, and why
- What the cure time is
- How hidden problems are handled
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
