Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Don’t use a blade near the sealant
- Stick to mild cleaners on glass
- Open vents or windows to let moisture out
- Check the gutters above the glazing for debris
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below long before you see it.
Glazing silicone for homes and businesses in Kinsbourne Green
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’re dealing with water escaping where a screen meets the wall and water tracking down the inner face of the glass, we can put it right.
Around Kinsbourne Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Common questions in Kinsbourne Green
Will you come out to Kinsbourne Green?
Yes. Kinsbourne Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Harpenden station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
How long will you be here?
Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Bigger jobs take longer, and we’ll tell you how long to expect.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Can you fix a leaking conservatory?
In many cases, as long as sealant is the cause. We trace the leak first, so you know what you’re paying for.
Do you fit new glass or sealed units?
No. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most jobs. In a small place like Kinsbourne Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Before we arrive
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Quotes for glazing silicone in Kinsbourne Green
The price is agreed before any work begins. It takes into account:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- The number of rooms or windows
- Whether the work is at height
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before any work starts.
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:
- Any previous sealing or DIY work
- Where the property is
- How we’d reach the joints
- A few photos by email, if you can
To get a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. We’ll send you a clear quote before any work starts.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Leaks from the roof covering or flashing (a roofer’s job)
- Rotten or badly damaged frames
- Glass that needs replacing
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Landlords and agents in Kinsbourne Green can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Why deal with it now?
Replacing a conservatory roof is major work. Where the water is getting in through sealant renewing the joint is the simpler fix. If it’s the roof itself, we’ll tell you. Where a wall is exposed, as many are in small places like Kinsbourne Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
Why us?

Glazing silicone in Kinsbourne Green: local notes
Historic houses like Childwickbury Manor (about 4.1 miles south-east) are a reminder that the area around Kinsbourne Green has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
If you let a flat or house near Harpenden station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. In the older streets around Saint Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Wood End School, the mastic around its windows and doors needs looking after like any other building’s.
