Glazing silicone in Shephall, done properly
Not every silicone suits glass. We use a neutral-cure glazing silicone that is suited to glass and the frame, finished with a neat, even bead. We work on glass-to-glass joints, glass balustrade bases and rooflights, and common reasons people get in touch are new silicone smeared over old sealant and stained, discoloured glazing silicone.
Homes around Shephall range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
All of our work is guaranteed for twelve months, in Shephall and everywhere else we cover.

Honest limits
A few problems are outside what sealant work can do:
- Condensation trapped between two panes
- Water coming through the roof rather than a sealant joint
- Glass that needs replacing

Signs you need glazing silicone in Shephall
Sunlight breaks sealant down and roof joints get the most sun. Old silicone hardens, cracks and loses its grip on the glass.
If you can see any of these, it’s time to have the joints looked at:
- Failed sealant around rooflight glass
- Mouldy sealant around glass panels
- Water tracking down the inner face of the glass
- Split or lifting silicone on glass
Homes close to Church of Saint Mary include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.

Why deal with it now?
A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone, and the leak normally returns. Cutting out and resealing properly lasts. Homes in smaller places like Shephall can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for most jobs. Parking around Shephall is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We trace the leak and confirm it’s a sealant joint.

- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.

Advice
Your questions about glazing silicone in Shephall
Do you cover smaller places like Shephall?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do older homes in Shephall need their sealant replacing?
If it hasn’t been replaced for some years, it’s generally worth it. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure, and many homes in Shephall may already be on their second or third set.
Do you reseal glass shower screens?
Yes. We remove the old sealant and reseal the wall and tray joints.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours, depending on how many joints need doing. We’ll tell you when we quote.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Squeegee the shower screen after each use
- Clear the conservatory gutters regularly
- Ventilate the conservatory to cut condensation
- Check the silicone on glass every year or so
Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.
Frames and glazing around Shephall
Historic houses like Aston Bury (about 1.6 miles south-east) are a reminder that the area around Shephall has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Peartree Spring Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Stevenage station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
