Our applicators work in South Down on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

Glazing silicone in South Down, done properly
We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. We are often asked to deal with a quick top-up bead that didn’t last and leaks where conservatory glass meets the frame, on glass balustrade bases, glass-to-frame joints and glass-to-glass joints.
Outdoor sealant needs dry, clean surfaces, so work on frames around South Down is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job.

Why it’s worth doing now in South Down
Fixing a leaking screen early protects what’s underneath. A small leak can reach the floor below before you notice. Older cottages and farmhouses around South Down can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

What affects the quote in South Down
The price is agreed before any work begins. It takes into account:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- How easy the joints are to reach
- Any mould that needs treating
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
What to tell us for a quote
You don’t need to know the technical terms. Just tell us:
- Where the property is
- Pictures of the joints, sent by email
- If someone has resealed it before
- The problem you’ve noticed
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.
What we’re called out for in South Down
Using a sealant not made for glass causes many failures. Some products do not bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
These are the problems we are asked about most:
- Rooflight joints letting water in
- New silicone smeared over old sealant
- Mouldy sealant around glass panels
- Glass-to-glass joints that have split
If you look after a building such as Twyford St Mary's Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
What to look for in a quote
- How long the guarantee is
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
- What preparation is included

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.
In the older streets around Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Should I try it myself first?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

How to look after the new joints
To keep the joints looking good and working properly:
- Act on drips or damp patches early
- Look over the glazing joints once a year
- Keep scrapers and blades away from the silicone
- Avoid strong solvents on or near the sealant
Don’t use blades or scrapers near the bead when cleaning the glass. A soft cloth or sponge is best.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below before you spot it.
