How we handle glazing silicone in Dukes Green
We do not replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints and that’s often where the water gets in. We work on conservatory frames, glass balustrade bases and glass-to-glass joints, and people most often call us about new silicone smeared over old sealant and failed sealant around rooflight glass.
Somewhere as small as Dukes Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, whatever its size.

Keeping the joints in good condition
Aftercare is simple:
- Use a gentle glass cleaner and a soft cloth
- Use gentle products around the joints
- Inspect the sealant on glazing annually
- Don’t use a blade near the sealant
Avoid scraping near the new silicone when you clean. Stick to a soft cloth.
Do not leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
Common questions in Dukes Green
Is glazing silicone in a coastal place like Dukes Green any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is Dukes Green 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.
Can a conservatory leak be sealed?
In many cases, as long as sealant is the cause. We trace the leak first, so you know what you’re paying for.
Do you have insurance?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Do you need glazing silicone in Dukes Green?
Silicone will not bond to a dirty surface. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
The problems people generally mention when they call include:
- Sealant that was laid over old silicone and failed
- Failed sealant around rooflight glass
- Water getting into a conservatory at the joints
- Split or lifting silicone on glass
If you let a flat or house near Berwick (Sussex) station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

What glazing silicone looks like in Dukes Green
Dukes Green is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to The Parish Church of St Michael the Archangel include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Alfriston School, larger buildings have plenty of frames, and the mastic around each one ages.

What else we do in Dukes Green
DIY sealant or a professional job?
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.
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.
Why act early in Dukes Green
Resealing cannot fix a failed unit or a cracked panel. We will tell you that rather than seal it anyway, so you can call the right trade. Older cottages and farmhouses around Dukes Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Dukes Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
