North Cray Glazing Silicone
Glazing silicone for conservatories, rooflights, glass panels and shower screens for North Cray, backed by a one-year guarantee. Ask us for a quote.
- Leaks from the base of a shower screen
- Water running down inside the glass
- Conservatory leaks at frame and glazing joints
What happens if it’s left?
Glazing joints need a sealant made for the job. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Glazing silicone for homes and businesses in North Cray
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. If you have split or lifting silicone on glass and glass-to-glass joints that have split, we can help.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first.
Big or small, you get the same one-year guarantee in North Cray and across Greater London.

How we quote for glazing silicone
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Mould in or behind the old joints
- The type of sealant required
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.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Photos by email, if that’s easy
- The address or postcode of the job
- If someone has resealed it before
- Roughly how big the job is
If you are in North Cray and need glazing silicone, phone 0345 464 0079 or email us. Tell us what the problem is and where, and you will get a clear quote before work begins.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Check the silicone on glass every year or so
- Open vents or windows to let moisture out
- Get a new leak looked at quickly
- Keep scrapers and blades away from the silicone
On shower screens, wipe or squeegee after use and let the room air. That slows mould growth on the bead.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Questions from North Cray
Do you cover North Cray for glazing silicone?
Yes. Our work covers London and the South East, and North Cray is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Is parking an issue for glazing silicone in North Cray?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can you just put new silicone over the old?
A top-up rarely holds. The new bead can’t grip the old one, so we remove the old sealant and clean the joint.
How long does glazing silicone take?
That depends on the amount of work, but most jobs take a few hours, depending on how many joints need doing. We will tell you when we quote.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will resealing stop my conservatory leaking?
It depends on the cause. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.
Do you replace glass?
That is not something we do. A misted unit has failed inside, and a glazier needs to replace it.
What guarantee do I get?
You get our one-year guarantee to every job we do.

How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on how many joints need doing. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Before we arrive
- Keep children and pets away from the work area
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit

North Cray homes and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.
As a London address, North Cray can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as Parish Church of St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we are called out for in North Cray
Silicone will not bond to a dirty surface. If the glass and frame weren’t cleaned properly, the bead can peel away early.
Signs it’s time to call us include:
- Drips on the inside of a conservatory window
- Leaks where conservatory glass meets the frame
- Stained, discoloured glazing silicone
- Failed sealant around rooflight glass
For site and facilities teams at buildings such as Royal Park Primary Academy, the mastic around its windows and doors needs looking after like any other building’s.
