Glazing silicone in Hadley Wood, done properly
Glazing silicone is a maintenance item. Sun, rain and movement wear it down, and once it cracks, water follows. Renewing it keeps glazing joints doing their job. We work on conservatory frames, glass balustrade bases and glass-to-glass joints, and people most often call us about mouldy sealant around glass panels and split or lifting silicone on glass.
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, letting in draughts and water.
Your job is guaranteed for a year, as with all our work.

How the visit works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for most jobs. For a job in Hadley Wood, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- 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.
How to prepare
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area

Hadley Wood questions
Do you work for landlords with property near Hadley Wood station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is parking a problem for a job in Hadley Wood?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
What guarantee do I get?
Our 12-month guarantee applies on all our work.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you replace glass?
Glass replacement isn’t our trade. We look after the sealant joints, and we’ll tell you if a unit looks like it has failed.
Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Quotes for glazing silicone in Hadley Wood
For a quick quote, just ask. The main things that affect it are:
- Mould in or behind the old joints
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- The type of sealant required
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
To make quoting easier, let us know:
- Any access issues, like height or stairs
- The address or postcode of the job
- Roughly how big the job is
- A few photos by email, if you can
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or send us an email.
What happens if it’s left?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Hadley Wood.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What glazing silicone looks like in Hadley Wood
Historic houses like Wyllyotts Manor (about 2.6 miles north) are a reminder that the area around Hadley Wood 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’s traditional sand mastic. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.
As a London address, Hadley Wood can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. In the older streets around St Paul's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Livingstone Primary and Nursery School? Then the mastic around its windows and doors needs looking after like any other building’s.

Should I try it myself first?
A careful DIYer can reseal a simple joint, 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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clean glass with a mild cleaner and a soft cloth
- Keep harsh solvents off the silicone
- Act on drips or damp patches early
- Squeegee the shower screen after each use
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple compared with fixing water damage later.
