Glazing silicone for homes and businesses in Round Bush
Not every silicone suits glass. We use a neutral-cure glazing silicone that’s suited to glass and the frame, finished with a neat, even bead. Typical jobs include leaking glazing joints on a rooflight and shower screens leaking along the wall or tray, on glass balustrade bases, shower screens and rooflights.
Homes in small places like Round Bush 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.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How the visit works
The work is kept neat and contained to the area we are working on. The job usually takes a few hours, depending on how many joints need doing, and we tell you how long to leave it before we go. For a village or hamlet like Round Bush, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

Advice
Surface by surface
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Signs you need glazing silicone in Round Bush
UV light ages silicone and roof joints get the most sun. Old silicone hardens, cracks and loses its grip to the glass and frame.
Common reasons people contact us include:
- Water tracking down the inner face of the glass
- Glass-to-glass joints that have split
- Water escaping where a screen meets the wall
- Split or lifting silicone on glass
For an older house near a landmark such as Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What sealant work cannot fix
We will always be straight with you, so here’s what sealant can’t fix:
- Glass that needs replacing
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Water coming through the roof rather than a sealant joint

Questions from Round Bush
Will you come out to Round Bush?
Yes, Round Bush is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Radlett station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Is the work guaranteed?
Our 12-month guarantee covers every job.
Will resealing stop my conservatory leaking?
It depends on the cause. Sealant joints we can renew but roof and panel problems need another trade.
Do you offer different sealant colours?
Generally, yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
Are you insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Glazing silicone in Round Bush: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like High Elms Manor (about 2.9 miles north-west) are a reminder that the area around Round Bush 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 is traditional sand mastic.
Letting a property close to Radlett station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Managing a site like Fair Field Junior School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Aftercare tips
So the new joints stay in good condition:
- Get a new leak looked at quickly
- Avoid scraping close to the bead
- Clean glass with a mild cleaner and a soft cloth
- Clear the conservatory gutters regularly
Use mild cleaners on and around the silicone. Strong solvents can soften or mark it.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
