Glazing silicone for homes and businesses in Clapgate
Across Clapgate, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method, with a sealant chosen for the joint. We work on glass balustrade bases, shower screens and conservatory frames, and common reasons people get in touch are glazing silicone that has cracked or come away and water escaping where a screen meets the wall.
Homes in small places like Clapgate often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What affects the cost of glazing silicone
There’s no set price list. What we look at:
- When we can work, for business premises
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
When you call or email, these details help:
- What’s wrong with the joints now
- Where the property is
- Whether it has been sealed before
- Any access issues, like height or stairs
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from an hour or two to most of a day, depending on the size of the job, including the tidy-up. Somewhere as small as Clapgate, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- The joints are checked before we leave.
How to prepare
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Clapgate homes and the weather
Historic houses like Much Hadham Palace (about 3.4 miles south) are a reminder that the area around Clapgate 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. 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.
Rented homes near Bishops Stortford station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. For site and facilities teams at buildings such as Albury Church of England Voluntary Aided Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we can’t put right
Sealant isn’t the answer to every problem, and we’ll tell you before we start. It won’t solve:
- Glass that needs replacing
- Condensation trapped between two panes
- Leaks from the roof covering or flashing (a roofer’s job)
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Glass-to-frame joints
- Shower screens
- Glass balustrade bases
- Rooflights
- Conservatory frames
- Glass-to-glass joints
How the job changes by surface
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
Aftercare tips
Looking after new joints is easy:
- Keep scrapers and blades away from the silicone
- Open vents or windows to let moisture out
- Clean glass with a mild cleaner and a soft cloth
- Run a squeegee over the glass when you’re done
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the problem grows.
Why act early in Clapgate
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before you notice. Where a wall is exposed, as many are in small places like Clapgate, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
