Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How we handle glazing silicone in High Leigh
Glass and frames expand and contract differently, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. If you have cracked silicone between glass panels and black or yellowed silicone on glass joints, we can put it right, on glass balustrade bases, glass-to-glass joints and shower screens alike.
Mastic can only go onto a dry, clean joint, so window work in High Leigh is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What does glazing silicone cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Can you fix a leaking conservatory?
Often, if the leak is at a sealant joint. We find where the water gets in first, so you know what you are paying for.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
How long does glazing silicone take?
Typically it takes a few hours for most jobs. Bigger jobs take longer, and we will say how long yours will take.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
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 the job changes by surface
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.

Common problems we fix in High Leigh
New silicone over old silicone won’t bond. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
Look out for any of the following:
- Water getting into a conservatory at the joints
- Cracked silicone between glass panels
- Glazing silicone that has cracked or come away
- Water tracking down the inner face of the glass
Homes close to Church of St Catherine & St Paul include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
Questions to ask before you book
- Whether they seal over old material or remove it
- What the cure time is
- What product goes in the joint
- What happens if they find a problem under the old sealant
