How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many joints need doing. For a village or hamlet like Colt's Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree the joints to be done.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.

Glazing silicone in Colt's Hill, done properly
We work across Colt's Hill on glazing joints for homes and businesses. From conservatories to shower screens, it’s the same careful method. If you have water tracking down the inner face of the glass and water getting into a conservatory at the joints, we can put it right, on shower screens, conservatory frames and glass balustrade bases alike.
In a village or hamlet like Colt's Hill, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Keeping the joints in good condition
Aftercare is simple:
- Clean glass with a mild cleaner and a soft cloth
- Look over the glazing joints once a year
- Get a new leak looked at quickly
- Run a squeegee over the glass when you are done
Follow the cure time we give you before the joints get wet so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we’ll find out which.
How we quote for glazing silicone
The price is agreed before any work begins. It’s based on:
- The size of the job
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- The type of sealant required
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
To help us quote quickly, let us know:
- Access, such as stairs, a lift or height
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
To get a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.
What we’re called out for in Colt's Hill
Sealant laid over old sealant doesn’t last. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
The problems people generally mention when they call are:
- Shower screens leaking along the wall or tray
- Leaking glazing joints on a rooflight
- Failed joints on frameless glass
- Glazing silicone that has cracked or come away
Homes close to Five Oak Green Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
- Is the old sealant removed completely?
- Whether you can choose the colour
- When the joint can take water or movement
- Who does the work, and how experienced they are
Windows and doors in Colt's Hill
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Paddock Wood station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For site and facilities teams at buildings such as Capel Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What happens if it’s left?
A leaking joint won’t fix itself. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. In a small place like Colt's Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
