About our glazing silicone in Kemsing
A frameless shower screen depends on its silicone. The joint down the wall and the one along the tray are common leak points, and we reseal both. Common call-outs are for black or yellowed silicone on glass joints and water getting into a conservatory at the joints, on glass-to-glass joints, glass balustrade bases and conservatory frames.
Around Kemsing, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Open vents or windows to let moisture out
- Keep conservatory gutters clear of leaves
- Run a squeegee over the glass when you’re done
- Get a new leak looked at quickly
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below long before you see it.

What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on how many joints need doing. Parking around Kemsing is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- 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.
Before we arrive
- Tell us if parking is tricky
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts

Kemsing homes and the weather
With historic houses such as Knole House (about 2.8 miles south) nearby, there’s older building stock in the area around Kemsing 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Otford station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

FAQs for Kemsing
Is Kemsing within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do glazing silicone in Kemsing?
Yes. Our work covers London and the South East, and Kemsing is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Cure times vary by product. We tell you how long to leave it before we go.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Kent.

Different surfaces, different methods
Conservatory frames
Exposed frame joints wear with the weather. A fresh bead seals them again.
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We renew it with a clear or matching glazing silicone.
Why it’s worth doing now in Kemsing
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames normally just need resealing, and we’ll tell you if that is not the case. In an older home around Kemsing, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Combining jobs into one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What we are called out for in Kemsing
Some conservatory leaks aren’t sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. That is why we trace the leak first.
Common reasons people contact us include:
- Conservatory leaks at frame and glazing joints
- Rooflight joints letting water in
- Water escaping where a screen meets the wall
- Stained, discoloured glazing silicone
If you look after a building such as Kemsing Primary School, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- How long to leave it before use
- The length of the guarantee
- What happens if they find a problem under the old sealant
- Whether you can choose the colour
When something else is needed
It helps to know what we can’t do too:
- A frame that needs repairing or replacing
- A sagging or failing conservatory roof
- Failed flashing around a conservatory
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.
