About our glazing silicone in Horton
Glass replacement is not something we do, and misting between panes means a failed sealed unit. Our work is the sealant joints and that’s often where the water gets in. If you are dealing with failed joints on frameless glass and conservatory leaks at frame and glazing joints, we can put it right, on glass-to-frame joints, rooflights and glass-to-glass joints alike.
Homes in small places like Horton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Why it’s worth doing now in Horton
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before it shows. Around Horton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

When to call us in Horton
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.
People normally contact us after spotting something like this:
- Mouldy sealant around glass panels
- Shower screens leaking along the wall or tray

Questions from Horton
Is Horton in your area for glazing silicone?
Yes, Horton is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is Horton within the area you cover?
Yes. Horton 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 just put new silicone over the old?
A top-up rarely holds. The new bead cannot grip the old one so we take it all out and start clean.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long will you be here?
It depends on the size of the job, but most jobs take anything from an hour or two to most of a day, depending on the size of the job. We’ll give you a better idea when we quote.
Is a special sealant needed for glass?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice, as some acetoxy types can attack certain metals.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.

Windows and doors in Horton
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. With historic houses such as Frogmore House (about 2.5 miles west) nearby, there’s older building stock in the area around Horton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Colnbrook Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St Michael, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Look over the glazing joints once a year
- Ventilate the conservatory to cut condensation
- Use gentle products around the joints
- Squeegee the shower screen after each use
Clear the conservatory gutters regularly so water doesn’t back up against the seals. Blocked gutters can push water where it shouldn’t go.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.
