Stonehill Green Glazing Silicone
Problem with your glazing joints in Stonehill Green? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

- Drips on the inside of a conservatory window
- New silicone smeared over old sealant
Glazing silicone in Stonehill Green
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. If you have failed joints on frameless glass and leaks from the base of a shower screen, we can help, on glass-to-frame joints, glass balustrade bases and conservatory frames alike.
Around Stonehill Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Each job carries a 12-month guarantee, large or small.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Other services in Stonehill Green
Different surfaces, different methods
Shower screens
Most shower screen leaks come from the wall or tray joint. Both are resealed with anti-fungal silicone.
Conservatory frames
Frame-to-wall joints on a conservatory move with the weather. They’re resealed with a suitable sealant.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Get a new leak looked at quickly
- Open vents or windows to let moisture out
- Keep harsh solvents off the silicone
- Don’t use a blade near the sealant
Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.
A small conservatory leak soon spreads. Water travels along the frame and into the wall so it’s best dealt with straight away.
What we are called out for in Stonehill Green
Sunlight breaks sealant down, especially on conservatory roofs. It goes brittle, cracks and stops sticking to the glass and frame.
Signs it’s time to call us include:
- Rooflight joints letting water in
- Shower screens leaking along the wall or tray
- Sealant that was laid over old silicone and failed
- Silicone pulling away from the glass
Managing a site like Hextable School? Then the mastic around its windows and doors needs looking after like any other building’s.

FAQs for Stonehill Green
Is Stonehill Green within the area you cover?
Yes. Stonehill Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Swanley station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you have insurance?
Yes. Mr Mastic is fully insured.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you just put new silicone over the old?
Many leaks we see come from exactly that. A proper job means cutting out, cleaning and resealing.

What do you need from me for a quote?

Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Glazing silicone in Stonehill Green: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hall Place and Gardens (about 2.4 miles north) are a reminder that the area around Stonehill Green 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.
Homes close to St Peter include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Swanley station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Leave it or put it right?
Replacing windows or a shower screen isn’t needed for a failed joint. Sound glass and frames normally just need resealing, and we’ll tell you if that is not the case. Around Stonehill Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
