Plashet Glazing Silicone
Professional glazing silicone in and around Plashet, with old sealant always removed completely and a 12-month guarantee.
- Leaking glazing joints on a rooflight
- Mouldy sealant around glass panels
- Leaks from the base of a shower screen
What happens if it’s left?
Glazing joints need a sealant made for the job. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why choose Mr Mastic in Plashet

Glazing silicone in Plashet, done properly
Frameless shower screens rely on sealant to keep water in. Leaks generally come from the wall joint or the tray joint, and we reseal both. If you have new silicone smeared over old sealant and split or lifting silicone on glass, we can help, whatever the surface.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Plashet.
Big or small, it’s backed by our one-year guarantee.

Questions from Plashet
I let a flat near Woodgrange Park station. Can you help?

Is parking an issue for glazing silicone in Plashet?
Parking in Plashet, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
What sealant do you use on glazing?
A glazing silicone chosen for the joint. Neutral-cure products suit most glass and frames.
Where do you work from?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we are fully insured.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most jobs. In a London area like Plashet, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Getting ready for the visit
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Advice
Frames and glazing around Plashet
With historic houses such as Valentines Mansion (about 2.2 miles north) nearby, there’s older building stock in the area around Plashet as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
For site and facilities teams at buildings such as Plashet School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Woodgrange Park station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

What the job involves on each surface
Shower screens
Mouldy or lifting sealant on a screen leaks. Cutting it out and resealing fixes it.
Glass balustrade bases
Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep scrapers and blades away from the silicone
- Run a squeegee over the glass when you’re done
- Use gentle products around the joints
- Keep air moving in the conservatory
Don’t use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
Do you need glazing silicone in Plashet?
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
Common reasons people contact us include:
- Failed joints on frameless glass
- Leaking glazing joints on a rooflight
- Split or lifting silicone on glass
- Water getting into a conservatory at the joints
In the older streets around Church of St Barnabas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
