Glazing silicone in Copthorne, done properly
Cracked, stained or lifting silicone on glass looks poor and can leak. It comes off cleanly, without marking the glass and reseal the joint. We work on glass-to-frame joints, rooflights and glass balustrade bases, and common reasons people get in touch are new silicone smeared over old sealant and conservatory leaks at frame and glazing joints.
In a smaller place like Copthorne, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Your job is guaranteed for a year, as with all our work.

How the job changes by surface
Shower screens
Most shower screen leaks come from the wall or tray joint. Both are resealed with anti-fungal silicone.
Conservatory frames
Leaks often start where the frame meets the wall. We remove the failed sealant and renew it.

What happens on the day
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. The work usually takes anything from an hour or two to most of a day, depending on the size of the job. For a job in Copthorne, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by finding the leak and making sure sealant is the cause.
- 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.
- 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
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints

Advice
Frames and glazing around Copthorne
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Gravetye Manor (about 4.5 miles south-east) are a reminder that the area around Copthorne has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near St John's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Fairway Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Copthorne is about 3 miles north-east of Crawley, in West Sussex. Wherever you are in the RH10 postcode area, our applicators can take on glazing silicone. Copthorne is one of 371 towns and villages in West Sussex where we work.
We cover every part of the RH10 and RH6 postcode area for glazing silicone and the streets around it. Local streets include Church Road, Brookside and Bridgelands, all of which we cover. Being close to the A264, Copthorne is easy for our applicators to reach. We also cover the places around Copthorne: Shipley Bridge (1 mile north-west), Forge Wood (1 mile west), Tinsley Green (1 mile west), Burstow (1 mile north) and Keeper's Corner (1 mile north-east). Within a short drive, we also cover Crawley (3 miles south-west), Horsham (10 miles south-west), Haywards Heath (10 miles south), Burgess Hill (12 miles south), East Grinstead (5 miles east) and Broadfield (4 miles south-west).
Around Copthorne
Around Copthorne, our work takes us to homes and buildings near Worth Park Gardens, The Cherry Tree pub and Hazelwick School, among other places. The closest station to Copthorne is Gatwick Airport station, roughly 2 miles north-west. Other landmarks nearby include Effingham Park Motor Museum (1.6 miles east) and County Mall (3 miles south-west). Not far away are Hedgecourt Lake.
Why act early in Copthorne
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before you notice. In a smaller place like Copthorne, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we will talk you through it.

What we are called out for in Copthorne
UV light ages silicone, especially on conservatory roofs. It goes brittle, cracks and stops sticking on the glass.
The problems people normally mention when they call are:
- Shower screens leaking along the wall or tray
- Silicone pulling away from the glass
- Rooflight joints letting water in
- Cracked silicone between glass panels
If you let a flat or house near Gatwick Airport station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Questions to ask before you book
- Whether they’re fully insured
- The length of the guarantee
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
Questions from Copthorne
Can you help a landlord with a rental near Gatwick Airport station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to Copthorne?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What sealant do you use on glazing?
We use a neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Can you reseal a frameless shower screen?
Yes. We remove the old sealant and reseal the wall and tray joints.
When something else is needed
We won’t take on work that will not last, so these are the limits:
- Glass that needs replacing
- Structural problems with a conservatory roof
- Frames that have decayed or split
