Glazing & conservatory sealant in Butler's Cross, Buckinghamshire
We cover Butler's Cross for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Rooflight joints letting water in
- Conservatory leaks at frame and glazing joints
- Shower screens leaking along the wall or tray
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Glazing silicone in Butler's Cross
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone that is suited to glass and the frame, and we tool it to a neat, even finish. If you have shower screens leaking along the wall or tray and a quick top-up bead that didn’t last, we can put it right, whatever the surface.
Around Butler's Cross, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Butler's Cross questions
Can you do glazing silicone in Butler's Cross?
Yes. Our work covers London and the South East, and Butler's Cross is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Do you cover smaller places like Butler's Cross?
Yes. Butler's Cross is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long does glazing silicone take?
It depends on the size of the job, but as a guide it takes a few hours, depending on how many joints need doing. We’ll tell you when we quote.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Do you fit new glass or sealed units?
No, our work is the silicone. A glazier replaces glass and units.
Can a conservatory leak be sealed?
Yes, when the leak is a failed sealant joint. If the cause is the roof, a panel or a unit, we will say so.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
How we quote for glazing silicone
For a quick quote, just ask. What matters most is:
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Working hours on commercial sites
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The rough size of the job
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
We quote each job on its own, so start by telling us what you need. Simply call 0345 464 0079 or email us and describe the job and send photos if you have them.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Open vents or windows to let moisture out
- Keep harsh solvents off the silicone
- Get a new leak looked at quickly
- Avoid scraping close to the bead
Clear the conservatory gutters regularly, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below before you spot it.

When to call us in Butler's Cross
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. That’s why we trace the leak first.
The problems people usually mention when they call are:
- Sealant that was laid over old silicone and failed
- Water getting into a conservatory at the joints
- Cracked silicone between glass panels
- Silicone pulling away from the glass
In the older streets around Church of St Peter and St Paul, the joint between an old wall and a newer frame is usually the first place rain gets in.
What to look for in a quote
- How the surfaces are prepared before sealing
- What happens if they find a problem under the old sealant
- Whether they seal over old material or remove it
- What guarantee comes with the work
Why deal with it now?
Replacing a conservatory roof is major work. If the leak is a failed sealant joint, resealing is far simpler. If the roof is the problem, we will say so. Older cottages and farmhouses around Butler's Cross can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
