Glazing silicone for homes and businesses in Henley-on-Thames
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on conservatory frames, rooflights and glass-to-frame joints, and common reasons people get in touch are stained, discoloured glazing silicone and water escaping where a screen meets the wall.
Around Henley-on-Thames, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
Whatever the size of the job, you get the same one-year guarantee in Henley-on-Thames and across Oxfordshire.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep scrapers and blades away from the silicone
- Look over the glazing joints once a year
- Squeegee the shower screen after each use
- Act on drips or damp patches early
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
A small conservatory leak soon spreads. Water runs along frames and down walls so it’s best dealt with right away.
Leave it or put it right?
If the problem is a misted unit or a broken panel, sealant won’t help. We say so plainly and point you to a glazier or roofer. In a smaller place like Henley-on-Thames, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before any work starts.
Why us?
- Full insurance on every job
- We leave the area clean and tidy
- A 12-month guarantee on all work
- 20+ years of sealant experience
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most jobs and we leave things clean and tidy. A visit to Henley-on-Thames is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

What glazing silicone looks like in Henley-on-Thames
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Greys Court (about 2.3 miles west) are a reminder that the area around Henley-on-Thames 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.
For an older house near a landmark such as Holy Trinity Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Trinity Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Henley-on-Thames questions
Do you cover smaller places like Henley-on-Thames?
Yes. Henley-on-Thames is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Henley-on-Thames for glazing silicone?
Yes. Our work covers London and the South East, and Henley-on-Thames is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Is a special sealant needed for glass?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice, as some acetoxy types can attack certain metals.
Where are you based?
We work from Crawley. Our applicators cover Henley-on-Thames, along with the rest of our area.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can I add another job to the visit?
Yes. Just list everything you need.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Common problems we fix in Henley-on-Thames
Sunlight breaks sealant down, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip on the glass.
These are the problems we’re asked about most:
- Leaks from the base of a shower screen
- Glazing silicone that has cracked or come away
- Water tracking down the inner face of the glass
- Black or yellowed silicone on glass joints
For landlords with property near Henley-On-Thames station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Glass balustrade bases
The base of a glass balustrade is generally sealed. When it fails, water can sit in the channel.
