Glazing & conservatory sealant in Northiam, East Sussex
Professional glazing silicone in and around Northiam, with every bit of old sealant taken out first.
- Sealant that was laid over old silicone and failed
- Cracked silicone between glass panels
- Split or lifting silicone on glass
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Glazing silicone for homes and businesses in Northiam
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. If you’re dealing with failed sealant around rooflight glass and leaks where conservatory glass meets the frame, we can help, whatever the surface.
Around Northiam, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months.

How the visit works
We keep the work tidy and contained to the joints we’re treating. The job normally takes anything from an hour or two to most of a day, depending on the size of the job, and we tell you how long to leave it before we go. For a village or hamlet like Northiam, the journey is planned in advance: 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 trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

Questions from Northiam
Is glazing silicone in Northiam guaranteed?
All our work, in Northiam and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you do glazing silicone in Northiam?
Yes, Northiam 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, and we’ll send you a clear quote.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Is a special sealant needed for glass?
A glazing silicone chosen for the joint. Neutral-cure products suit most glass and frames.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Why not top up the existing silicone?
It does not last. Fresh silicone won’t bond to cured silicone, so we remove the old sealant and clean the joint.
Do you fit new glass or sealed units?
No. We renew the sealant. A glazier replaces glass and units.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What affects the cost of glazing silicone
The price is agreed before any work begins. It’s based on:
- Any mould that needs treating
- Which sealant suits the joint
- Whether the work is at height
- Whether old sealant or filler has to be cut out
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- The type of property
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Leave it or put it right?
Resealing can’t fix a failed unit or a cracked panel. We say so plainly, so you can call the right trade. In a small place like Northiam, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Fully insured
- ARBOMaster approved applicator
- Quality sealants from Arbo and Everbuild
- We agree the colour with you first

What else we do in Northiam
Glazing silicone in Northiam: local notes
With historic houses such as Great Dixter (about 0.5 miles west) nearby, there’s older building stock in the area around Northiam as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s 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 Northiam Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
