Advice
How we handle glazing silicone in Vale of Health
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 both get fresh anti-fungal silicone. We work on glass-to-glass joints, conservatory frames and rooflights, and people most often call us about water running down inside the glass and glass-to-glass joints that have split.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
All of our work is guaranteed for twelve months, in Vale of Health and everywhere else we cover.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Squeegee the shower screen after each use
- Keep air moving in the conservatory
- Clear the conservatory gutters regularly
- Use gentle products around the joints
Squeegee a shower screen after each shower and let the room air. That slows mould growth on the bead.
Do not leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Condensation trapped between two panes
- Structural problems with a conservatory roof
- Leaks from the roof covering or flashing (a roofer’s job)
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

How the job changes by surface
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. Failed sealant there lets water collect.
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
Common questions in Vale of Health
Is parking an issue for glazing silicone in Vale of Health?
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.
Do you cover Vale of Health for glazing silicone?
Yes. We work across London and the South East, and Vale of Health is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is the work guaranteed?
Our 12-month guarantee applies on all our work.
Why not top up the existing silicone?
New silicone will not bond to old silicone and water gets between the layers. We cut out the old sealant first.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Can you fix a leaking conservatory?
That depends where the water is getting in. Sealant joints we can renew but roof and panel problems need another trade.
How long will you be here?
A typical job takes anything from an hour or two to most of a day, depending on the size of the job, including preparation and clearing up. Your quote will say how long we expect yours to take.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

What glazing silicone looks like in Vale of Health
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
As a London address, Vale of Health can be tricky for parking: let us know about parking bays, permits or a driveway. Rented homes near Hampstead Heath station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Managing a site like Christ Church Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

How we quote for glazing silicone
We do not publish a price list. The quote depends on:
- The size of the job
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- Which sealant suits the joint
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- The rough size of the job
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
Why deal with it now?
Replacing windows or a shower screen is not needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes, and we’ll tell you if that is not the case. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
