How it works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job generally takes a few hours, depending on how many joints need doing. Parking in a town like Gravesend is generally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We check the joints and, where safe, run water over them.
How to prepare
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Mention any tricky access

Glazing silicone in Gravesend
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 we reseal both. We work on glass balustrade bases, rooflights and glass-to-glass joints, and common reasons people get in touch are water getting into a conservatory at the joints and leaks from the base of a shower screen.
Gravesend mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. All of them depend on a sound bead of mastic between frame and wall.
All our work comes with a 12-month guarantee, wherever you are in Kent.

Gravesend: your questions answered
Is glazing silicone in a coastal place like Gravesend any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover Gravesend for glazing silicone?
Yes. Our work covers London and the South East, and Gravesend is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Is it possible to redo the silicone on a shower screen?
We can. The old bead comes off without marking the glass before cleaning and resealing.
Do you replace glass?
No, our work is the silicone. Glass and sealed units need a glazier.
How much does glazing silicone cost in Gravesend?
Size, access and the old material all affect the cost. Ask us for a quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Gravesend.
Is a special sealant needed for glass?
A glazing silicone chosen for the joint. Neutral-cure products suit most glass and frames.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
When something else is needed
A few problems are outside what sealant work can do:
- Structural problems with a conservatory roof
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Cracked or broken glass
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.

What else we do in Gravesend
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Do you need glazing silicone in Gravesend?
Shower screen silicone gets wet every day. Mould gets into it and the edges begin to peel.
Look out for these signs:
- Conservatory leaks at frame and glazing joints
- Drips on the inside of a conservatory window
- Failed sealant around rooflight glass
- Glass-to-glass joints that have split
For site and facilities teams at buildings such as Whitehill Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Gravesend homes and the weather
Gravesend is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. Historic houses like Cobham College (about 2.9 miles south) are a reminder that the area around Gravesend 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 the older streets around Christ Church Milton, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Gravesend station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

What affects the quote in Gravesend
The price is agreed before any work begins. It takes into account:
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- The size of the job
- Whether there’s mould to deal with
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
What we need to know
To make quoting easier, let us know:
- Where the property is
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking

For landlords and businesses
If you manage several properties in or around Gravesend, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What happens if it’s left?
Resealing cannot fix a failed unit or a cracked panel. We say so plainly, so you can call the right trade. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
