Glazing silicone for homes and businesses in Hadham Cross
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. If you’re dealing with water running down inside the glass and new silicone smeared over old sealant, we can help, on glass-to-glass joints, conservatory frames and glass balustrade bases alike.
In a village or hamlet like Hadham Cross, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, in Hadham Cross and everywhere else we cover.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Frames and glazing around Hadham Cross
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Much Hadham Palace (about 0.8 miles north-east) are a reminder that the area around Hadham Cross has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Bishops Stortford station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Managing a site like St Andrew's CofE Primary School and Nursery? Then its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
Why it’s worth doing now in Hadham Cross
You do not need new glazing because the sealant has gone. Sound glass and frames usually just need resealing. Around Hadham Cross, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.

What we do, step by step
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to most of a day, depending on the size of the job. In a small place like Hadham Cross, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

Glass and frames expand and contract with the temperature, and they don’t move by the same amount. In time, the sealant splits or pulls away.
It’s worth asking for a quote if you see:
- Leaking glazing joints on a rooflight
- Failed joints on frameless glass
- Leaks where conservatory glass meets the frame
- Black or yellowed silicone on glass joints
