About our glazing silicone in St Mary Bourne
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. Common call-outs are for leaks where conservatory glass meets the frame and black or yellowed silicone on glass joints, across conservatory frames, glass-to-frame joints and rooflights.
Around St Mary Bourne, 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.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

St Mary Bourne: your questions answered
Do you cover St Mary Bourne for glazing silicone?
Yes, St Mary Bourne is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Is St Mary Bourne within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you fit new glass or sealed units?
That’s not something we do. A misted unit has failed inside and needs replacing by a glazier.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Is it possible to redo the silicone on a shower screen?
Yes, we do these often. We use anti-fungal silicone suited to bathrooms.
How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work 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 St Mary Bourne, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- 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.
Preparing for the visit
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work

Glazing silicone in St Mary Bourne: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as St Mary Bourne Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Whitchurch (Hampshire) station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. In the older streets around Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why it’s worth doing now in St Mary Bourne
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before it shows. Older cottages and farmhouses around St Mary Bourne can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- Arbo and Everbuild products

Can I do it myself?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Look over the glazing joints once a year
- Wipe the screen down after showering
- Use gentle products around the joints
- Clear the conservatory gutters regularly
On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.
Conservatory leaks rarely stay small. Water runs along frames and down walls so it’s best dealt with straight away.
Surface by surface
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. When it splits, water can get into the frame.
What sealant work cannot fix
In fairness, some problems need a different trade:
- Leaks from the roof covering or flashing (a roofer’s job)
- A sealed unit that has misted inside
- A sagging or failing conservatory roof
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.
What we seal
