What the job involves on each surface
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Glass-to-frame joints
Old sealant is removed carefully from the glass before new glazing silicone goes in.
Glazing silicone for homes and businesses in Shillington
Not every silicone suits glass. We use a neutral-cure glazing silicone that’s suited to glass and the frame, finished with a neat, even bead. We are often asked to deal with glass-to-glass joints that have split and new silicone smeared over old sealant, across glass balustrade bases, conservatory frames and shower screens.
Homes in small places like Shillington 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.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

Do you need glazing silicone in Shillington?
New silicone over old silicone will not bond. Many failed joints we see have been topped up rather than cut out leaving a path for water.
If you can see any of these, it’s time to have the joints looked at:
- Failed joints on frameless glass
- Silicone pulling away from the glass
- A quick top-up bead that didn’t last
- Water getting into a conservatory at the joints
Schools such as Shillington Lower School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How we quote for glazing silicone
We quote each job individually. These are the things that affect it:
- The type of sealant required
- When we can work, for business premises
- Whether the work is at height
- How much there is to do
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- Photos by email, if that is easy
- What’s wrong with the joints now
- The type of property
- Access, such as stairs, a lift or height

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Use a gentle glass cleaner and a soft cloth
- Check the silicone on glass every year or so
- Keep scrapers and blades away from the silicone
- Keep conservatory gutters clear of leaves
Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.
What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. In a small place like Shillington, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Mention any tricky access

Advice
Shillington: your questions answered
Can you help a landlord with a rental near Arlesey station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Shillington?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Where do you work from?
We work from Crawley. Our applicators cover Shillington.
How long does glazing silicone take?
A typical job takes anything from an hour or two to most of a day, depending on the size of the job. We will confirm how long when we quote.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Can you reseal a frameless shower screen?
We can. The old bead comes off without marking the glass before cleaning and resealing.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Why deal with it now?
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Older cottages and farmhouses around Shillington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before we start.

What glazing silicone looks like in Shillington
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.
Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Arlesey station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
