Glazing silicone across Thedden and nearby, with old sealant always removed completely.

- Silicone pulling away from the glass
- Leaking glazing joints on a rooflight
How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- When we can work, for business premises
- How many areas need sealing
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.
What we need to know
To make quoting easier, please include:
- The rough size of the job
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
- 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, and we will take it from there.
Glazing silicone in Thedden, done properly
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. We work on glass-to-glass joints, rooflights and shower screens, and common reasons people get in touch are conservatory leaks at frame and glazing joints and leaking glazing joints on a rooflight.
Homes in small places like Thedden 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.
All our work is covered by our one-year guarantee.

When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- A sagging or failing conservatory roof
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A frame that needs repairing or replacing
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
Surfaces we seal
- Shower screens
- Glass balustrade bases
- Conservatory frames
- Glass-to-frame joints
- Glass-to-glass joints
- Rooflights
What happens if it’s left?
Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. In a small place like Thedden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why Thedden customers choose us
- Any old sealant cut out fully, not covered over
- An ARBOMaster approved applicator
- Domestic, commercial and hotel work
- Sealant colour chosen to suit
See our cost guide and what customers say.
Looking after it afterwards
Looking after new joints is easy:
- Clear the conservatory gutters regularly
- Stick to mild cleaners on glass
- Wipe the screen down after showering
- Inspect the sealant on glazing annually
Avoid scraping near the new silicone when cleaning the glass. A soft cloth or sponge is best.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.
Common questions in Thedden
Will you come out to Thedden?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do glazing silicone in Thedden?
Yes, Thedden is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Can a conservatory leak be sealed?
It depends on the cause. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.
Where do you work from?
We are based in Crawley, and we work across South East England, London and Scotland.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
How long does the job take?
It depends on the size of the job, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We’ll tell you when we quote.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels, and we’re fully insured.
What glazing silicone looks like in Thedden
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Bentworth Hall (about 1 mile west) are a reminder that the area around Thedden has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Alton station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. Schools such as Amery Hill School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St Peter's, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Surface by surface

What else we do in Thedden
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
