Glazing & conservatory sealant in Keycol, Kent
Problem with your glazing joints in Keycol? We remove the old material, prepare the joints and seal them properly.
- Rooflight joints letting water in
- Sealant that was laid over old silicone and failed
- Glazing silicone that has cracked or come away
When it is not the sealant
Sealant is not the answer to every problem, and we will tell you before any work starts. It will not solve:
- Cracked or broken glass
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Rotten or badly damaged frames
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Rooflights
- Glass-to-glass joints
- Glass balustrade bases
- Shower screens
- Glass-to-frame joints
- Conservatory frames
Glazing silicone in Keycol
Glass and frames expand and contract differently, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. If you have failed joints on frameless glass and stained, discoloured glazing silicone, we can put it right, whatever the surface.
Somewhere as small as Keycol, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months, in Keycol and everywhere else we cover.

How the job changes by surface
Glass balustrade bases
Outdoor balustrade joints face the weather. Renewing the sealant keeps water out of the channel.
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.
What happens on the day
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most jobs. Somewhere like Keycol needs a little journey planning: 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 find where water is getting in and check whether it’s a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Signs you need glazing silicone in Keycol
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
It’s worth asking for a quote if you see:
- Leaking glazing joints on a rooflight
- Failed joints on frameless glass
- New silicone smeared over old sealant
- Black or yellowed silicone on glass joints
If you look after a building such as Borden Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- How the colour is chosen
- How the joint is cleaned and prepared
Frames and glazing around Keycol
Keycol is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Newington station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you live in an older home near Church of St Bartholomew, the joint between an old wall and a newer frame is normally the first place rain gets in.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Keep scrapers and blades away from the silicone
- Wipe the screen down after showering
- Act on drips or damp patches early
- Clean glass with a mild cleaner and a soft cloth
Avoid scraping near the new silicone when cleaning the glass. A soft cloth or sponge is best.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.
DIY sealant or a professional job?
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.
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 fails, we can still redo it.
