Glazing Silicone in Oakwood
Glazing silicone for conservatories, rooflights, glass panels and shower screens for homes and businesses in Oakwood and across Greater London. ARBOMaster approved applicators, fully insured, with a one-year guarantee.

What we are called out for in Oakwood
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the joint starts to lift.
If you can see any of these, it’s time to have the joints looked at:
- Rooflight joints letting water in
- Split or lifting silicone on glass
- Water getting into a conservatory at the joints
- Drips on the inside of a conservatory window
As a London address, Oakwood can be tricky for parking: let us know about parking bays, permits or a driveway.
What your quote should include
- Who turns up on the day
- Which colour the sealant will be
- What happens if the job turns out different
- Whether the sealant suits the joint
Glazing silicone in Oakwood
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass before the new bead goes in. Typical jobs include failed sealant around rooflight glass and stained, discoloured glazing silicone, on conservatory frames, rooflights and glass balustrade bases.
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, which is when draughts and damp patches appear in homes in Oakwood.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- A roof that has moved or dropped
- Frames that have decayed or split
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.

- Glass-to-frame joints

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Why act early in Oakwood
Topping up old silicone can look like a fix, but silicone doesn’t stick to silicone, and the leak generally returns. Cutting out and resealing properly lasts. In a flat in Oakwood, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
Why choose Mr Mastic in Oakwood

Glazing silicone in Oakwood: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Winchmore Hill station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you live in an older home near St Thomas's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for most jobs. For a job in Oakwood, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in

Questions from Oakwood
Is parking a problem for a job in Oakwood?
Parking in Oakwood, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you work for landlords with property near Winchmore Hill station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Which silicone is used for glass joints?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Different surfaces, different methods
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
