What the job involves on each surface
Rooflights
Rooflights get the full force of the weather. Its sealant ages faster than vertical joints.
Glass balustrade bases
We reseal the joint where the glass meets the base channel. We don’t install or replace glass.
Glazing silicone for homes and businesses in Exton
We work across Exton on glazing joints for homes and businesses. From conservatories to shower screens, it’s the same careful method. Typical jobs include drips on the inside of a conservatory window and split or lifting silicone on glass, on conservatory frames, shower screens and rooflights.
Somewhere as small as Exton, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

What glazing silicone looks like in Exton
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. With historic houses such as Hinton Ampner House (about 4.2 miles north) nearby, there’s older building stock in the area around Exton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of St Peter and St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Exton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Why it’s worth doing now in Exton
Replacing windows or a shower screen is not needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes, and we’ll tell you if that’s not the case. In a small place like Exton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Do you need glazing silicone in Exton?
UV light ages silicone and roof joints get the most sun. Old silicone hardens, cracks and loses its grip to the glass and frame.
Look out for any of the following:
- Conservatory leaks at frame and glazing joints
- Cracked silicone between glass panels
- Water running down inside the glass
- Leaks from the base of a shower screen
If you look after a building such as Meonstoke Church of England Infant School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
- What happens if the job turns out different
- How the colour is chosen
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
What affects the cost of glazing silicone
We quote each job individually. This is what makes a difference:
- Any mould that needs treating
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- The product the joint needs
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
When you contact us, it’s useful to know:
- The problem you’ve noticed
- Any previous sealing or DIY work
- Photos by email, if that is easy
- How many joints, rooms or windows are involved
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or email us with the details and send pictures if you have them.
Exton questions

Will it make a mess?

What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Do you guarantee glazing sealant work?

Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
