Glazing silicone in Southgate
Glazing silicone is a maintenance item. Weather and movement take their toll, and once it cracks, water follows. Resealing puts that right. If you have black or yellowed silicone on glass joints and failed sealant around rooflight glass, we can help, whatever the surface.
Many houses in smaller places like Southgate have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What we do, step by step
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours, depending on how many joints need doing. Parking around Southgate is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
- The glass and frame are cleaned and degreased.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit
- Mention any tricky access
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks

Frames and glazing around Southgate
Historic houses like Tyes Place (about 5 miles south) are a reminder that the area around Southgate 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Southgate Primary? Then the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near St Mary's, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Southgate is about 1 mile south-west of Crawley, in West Sussex. Whether you’re in the middle of Southgate or further out, glazing silicone is available for homes and businesses alike, from flats and houses to offices and hotels. Southgate is one of 371 places in West Sussex where we work for glazing silicone.
We cover every part of the RH10 and RH11 postcode area for glazing silicone. We cover properties on Oak Road, Cook Road and Colet Road and the roads around them.

We also cover the places around Southgate: Crawley (1 mile north-east), Tilgate (1 mile east), West Green (1 mile north), Three Bridges (1 mile north-east) and Langley Green (2 miles north).

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Act on drips or damp patches early
- Use gentle products around the joints
- Ventilate the conservatory to cut condensation
- Check the silicone on glass every year or so
On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we will tell you which.
Southgate questions
Is it worth replacing old sealant in an older home in Southgate?
Often, yes: cracked, shrunken or mouldy sealant has done its job. New sealant will not stick to old, so the old bead has to come out completely first.
Do you work for landlords with property near Crawley station?
Yes. We work for landlords and agents as well as homeowners. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you work in Southgate?
Yes. We cover Southgate and the rest of West Sussex. To book, phone 0345 464 0079 or drop us an email.
What guarantee do I get?
Our 12-month guarantee applies on all our work.
Can you reseal a frameless shower screen?
Yes. We remove the old sealant and reseal the wall and tray joints.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How much does glazing silicone cost in Southgate?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Why it’s worth doing now in Southgate
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 choose a glazing silicone instead. In an older home around Southgate, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

What we are called out for in Southgate
Sunlight breaks sealant down, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.
The most common problems we see are:
- Cracked silicone between glass panels
- Leaks from the base of a shower screen
- Sealant that was laid over old silicone and failed
- Silicone pulling away from the glass
For landlords with property near Crawley station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
