Boxley Glazing Silicone
Glazing joints in Boxley need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Failed sealant around rooflight glass
- Split or lifting silicone on glass
- Shower screens leaking along the wall or tray
When to call us in Boxley
Sunlight breaks sealant down, especially on conservatory roofs. It goes brittle, cracks and stops sticking on the glass.
Any of these means the joints need attention:
- Leaks where conservatory glass meets the frame
- Sealant that was laid over old silicone and failed
- Water escaping where a screen meets the wall
- Split or lifting silicone on glass
If you let a flat or house near Maidstone East station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Glazing silicone for homes and businesses in Boxley
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We cut it out and reseal with a glazing silicone suited to the joint. We work on rooflights, shower screens and glass-to-frame joints, and people most often call us about sealant that was laid over old silicone and failed and failed joints on frameless glass.
Mastic can only go onto a dry, clean joint, so window work in Boxley is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

Aftercare tips
A little care helps the new joints last. Our advice:
- Squeegee the shower screen after each use
- Inspect the sealant on glazing annually
- Keep air moving in the conservatory
- Keep scrapers and blades away from the silicone
Keep the new joints dry for as long as we advise so the silicone can set properly. After that, clean glass with a mild cleaner.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the leak gets worse.

For a quick quote, just ask. What matters most is:

FAQs for Boxley
Will you come out to Boxley?
Yes. Boxley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is there any odour?
Sometimes, a little. It fades as the sealant cures.
How long will you be here?
As a guide, most jobs take a few hours for most jobs. Larger jobs naturally take longer, and we’ll say how long yours will take.
Where do you work from?
Mr Mastic is based in Crawley. We cover Boxley and the rest of Kent.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
What sealant do you use on glazing?
A glazing-grade silicone is best. Ours is a neutral-cure glazing silicone with anti-fungal products in bathrooms.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Why it’s worth doing now in Boxley
You do not need new glazing because the sealant has gone. Sound glass and frames normally just need resealing, and we will tell you if that is not the case. Where a wall is exposed, as many are in small places like Boxley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What you get with us
- 20+ years of sealant experience
- A 12-month guarantee on all work

The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes anything from an hour or two to most of a day, depending on the size of the job. For a village or hamlet like Boxley, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children

Related advice
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When it isn’t the sealant
It helps to know what we cannot do:
- A roof that has moved or dropped
- A frame that needs repairing or replacing
- Leaks from the roof covering or flashing (a roofer’s job)
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Glass balustrade bases
- Glass-to-glass joints
- Rooflights
- Glass-to-frame joints
- Shower screens
- Conservatory frames
Boxley homes and the weather
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. Historic houses like Stoneacre (about 4 miles south) are a reminder that the area around Boxley has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Sandling Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as St Mary's and All Saints Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
