Glazing silicone in Hill End, done properly
Glass and frames expand and contract differently, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. We work on conservatory frames, glass-to-frame joints and rooflights, and the jobs we see most are water tracking down the inner face of the glass and sealant that was laid over old silicone and failed. Looking for a local mastic man in Hill End? That is us, with 20+ years’ experience.
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, which is when draughts and damp patches appear in homes in Hill End.
A 12-month guarantee comes as standard.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Avoid scraping close to the bead
- Wipe the screen down after showering
- Clear the conservatory gutters regularly
- Ventilate the conservatory to cut condensation
Clear the conservatory gutters regularly so water doesn’t back up against the seals. Overflowing gutters can cause leaks of their own.
Conservatory leaks rarely stay small. Water runs along frames and down walls, so get it looked at when you first see it.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- A sealed unit that has misted inside
- Failed flashing around a conservatory
- A roof that has moved or dropped
Not sure which it is? You can ring 07833 053749 or drop us an email and we’ll tell you honestly before booking.

Frames and glazing around Hill End
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Harefield Baptist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Hill End is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Hill End questions
Can you do glazing silicone in Hill End?
Yes. Our work covers London and the South East, and Hill End is part of that. Just call 07833 053749 or email us with a few details of the job.
Can parking be tricky for a visit in Hill End?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient.
Do you reseal glass shower screens?
Yes. We remove the old sealant and reseal the wall and tray joints.
Do you fit new glass or sealed units?
No, our work is the silicone. Glass and sealed units need a glazier.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We’ll tell you when we quote.
Can you just put new silicone over the old?
Silicone does not stick to silicone and water gets between the layers. We cut out the old sealant first.
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for most jobs. In Hill End, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Leave it or put it right?
A leaking joint won’t fix itself. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Hill End, the repair is bigger than the sealant job would have been.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What we’re called out for in Hill End
Heat and cold make glass and frames move, and they do not move by the same amount. In time, the sealant splits or pulls away.
Any of these means the joints need attention:
- Water escaping where a screen meets the wall
- Black or yellowed silicone on glass joints
- Glass-to-glass joints that have split
- Sealant that was laid over old silicone and failed
For site and facilities teams at buildings such as Harefield Infant School, the mastic around its windows and doors needs looking after like any other building’s.
