Glazing silicone in Round Street
Sealant on glazing does not last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. If you have water getting into a conservatory at the joints and leaks from the base of a shower screen, we can help, on shower screens, glass-to-frame joints and glass balustrade bases alike.
Homes in small places like Round Street 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How we quote for glazing silicone
We quote each job individually. These are the things that affect it:
- Mould in or behind the old joints
- The number of rooms or windows
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Asking for a quote
When you contact us, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that is easy
- Any previous sealing or DIY work
- The rough size of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
When something else is needed
Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Water coming through the roof rather than a sealant joint
- Rotten or badly damaged frames
- A roof that has moved or dropped
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Glass-to-frame joints
- Rooflights
- Conservatory frames
- Shower screens
- Glass-to-glass joints
- Glass balustrade bases

Round Street homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Cobham College (about 0.9 miles east) are a reminder that the area around Round Street has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Cobham Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Sole Street station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Round Street is about 3 miles south of Gravesend, in Kent. From the centre of Round Street to the outskirts, we cover glazing silicone for every kind of property. Across Kent, we cover 922 places, and Round Street is one of them. There’s also a page for London, roughly 22 miles from Round Street.
All of DA13 is within our area for glazing silicone. We also cover the places around Round Street: Sole Street (1 mile south), Gold Street (1 mile south-east), Nash Street (1 mile west), Meopham (1 mile south-west) and Henley Street (1 mile south-east).

What’s near Round Street
Typical jobs here are in homes near The Railway Inn, Jeskyns and Meopham School, among other places. The closest station to Round Street is Sole Street station, roughly 0.6 miles south.

Common problems we fix in Round Street
Sunlight breaks sealant down and roof joints get the most sun. Old silicone hardens, cracks and loses its grip on the glass.
Look out for these signs:
- Conservatory leaks at frame and glazing joints
- Drips on the inside of a conservatory window
- Mouldy sealant around glass panels
- Water escaping where a screen meets the wall
For an older house near a landmark such as St Mary's Room, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- Is VAT in the price?
- Whether you can choose the colour
- How long to leave it before use
- Who turns up on the day
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes anything from an hour or two to most of a day, depending on the size of the job, depending on the amount of work. Somewhere as small as Round Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit
- Tell us if parking is tricky
- Mention any tricky access
- Mention any sign-in or site rules at work premises

Related advice
Why act early in Round Street
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Where a wall is exposed, as many are in small places like Round Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
