- Water tracking down the inner face of the glass
- Stained, discoloured glazing silicone
- Leaks from the base of a shower screen
Looking after it afterwards
After the cure time, these simple habits help:
- Run a squeegee over the glass when you are done
- Avoid scraping close to the bead
- Keep air moving in the conservatory
- Keep conservatory gutters clear of leaves
Keep the new joints dry for as long as we advise. From then on, a mild glass cleaner is all it needs.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.
Glazing silicone in St Paul's Walden
Sealant on glazing doesn’t last for ever. Sun, rain and movement wear it down and cracked joints let water in. Resealing puts that right. We are often asked to deal with water tracking down the inner face of the glass and glazing silicone that has cracked or come away, across rooflights, glass-to-glass joints and glass-to-frame joints.
Mastic can only go onto a dry, clean joint, so window work in St Paul's Walden is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Every job comes with a 12-month guarantee.

Windows and doors in St Paul's Walden
With historic houses such as Knebworth House (about 2.4 miles south-east) nearby, there’s older building stock in the area around St Paul's Walden as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as St Paul's Walden Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as All Saints Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Letting a property close to Stevenage station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Why deal with it now?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Where a wall is exposed, as many are in small places like St Paul's Walden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

How the visit works
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours for most jobs in most cases. For a village or hamlet like St Paul's Walden, 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.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
- Move anything stored near the joints

How we quote for glazing silicone
Jobs vary more than people expect. What affects the quote:
- Which sealant suits the joint
- How easy the joints are to reach
- The number of rooms or windows
- The amount of work
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before we start.
Helping us quote
To make quoting easier, let us know:
- What’s wrong with the joints now
- Whether it’s a home or a business
- Where the property is
- How we’d reach the joints
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
How the job changes by surface
Conservatory frames
Leaks often start where the frame meets the wall. We cut out the old sealant and reseal.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
