How we handle glazing silicone in Letty Green
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. Typical jobs include water running down inside the glass and conservatory leaks at frame and glazing joints, across glass-to-glass joints, glass balustrade bases and glass-to-frame joints.
Around Letty Green, 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.
Whatever the size of the job, it’s backed by our one-year guarantee.

Advice
How we quote for glazing silicone
The price is agreed before any work begins. It’s based on:
- The product the joint needs
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- Access and height
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
Helping us quote
To make quoting easier, please include:
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use gentle products around the joints
- Stick to mild cleaners on glass
- Ventilate the conservatory to cut condensation
- Check the silicone on glass every year or so
Avoid scraping near the new silicone when you clean. A soft cloth or sponge is best.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we’ll find out which.
What glazing silicone looks like in Letty Green
Historic houses like Hatfield House (about 3.4 miles south-west) are a reminder that the area around Letty Green 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Hertingfordbury Cowper Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. In the older streets around St John's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Hertford North station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Why it’s worth doing now in Letty Green
Topping up old silicone can look like a fix, but silicone doesn’t stick to silicone and water soon finds its way back. Cutting out and resealing properly lasts. In a small place like Letty Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.
