Glazing & conservatory sealant in Alciston, East Sussex
Glazing silicone for Alciston and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Cracked silicone between glass panels
- Conservatory leaks at frame and glazing joints
- Sealant that was laid over old silicone and failed
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Keep harsh solvents off the silicone
- Inspect the sealant on glazing annually
- Keep scrapers and blades away from the silicone
- Open vents or windows to let moisture out
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
About our glazing silicone in Alciston
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. If you have leaks where conservatory glass meets the frame and water escaping where a screen meets the wall, we can help, on glass-to-frame joints, glass balustrade bases and glass-to-glass joints alike.
Mastic can only go onto a dry, clean joint, so window work in Alciston is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

- Shower screens
- Glass balustrade bases
- Glass-to-frame joints
- Conservatory frames
- Rooflights
- Glass-to-glass joints

How we quote for glazing silicone
Call for a quick quote. What matters most is:
- Access and height
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

- How we’d reach the joints
- The address or postcode of the job

Alciston: your questions answered
I let a flat near Berwick (Sussex) station. Can you help?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Is Alciston in your area for glazing silicone?
Yes. We work across London and the South East, and Alciston is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
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’ll explain our choice.
Can you replace a misted double-glazed unit?
No, our work is the silicone. Glass and sealed units need a glazier.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What information do you need?
A short description and the location. If we need more, we’ll ask.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Why act early in Alciston
Replacing a conservatory roof is major work. Where the water is getting in through sealant renewing the joint is the simpler fix. If it’s the roof itself, we’ll tell you. Older cottages and farmhouses around Alciston can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits. We’ll give you a clear quote for the lot.

Alciston homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Charleston Farmhouse (about 1.3 miles north-west) nearby, there’s older building stock in the area around Alciston as well as newer homes. 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 landlords with property near Berwick (Sussex) station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. In the older streets around The Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours, depending on how many joints need doing. Somewhere like Alciston needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
- Move anything stored near the joints
