Oval Glazing Silicone
We cover Oval for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly.
- Failed sealant around rooflight glass
- Black or yellowed silicone on glass joints
- Leaks from the base of a shower screen
What affects the cost of glazing silicone
Every job gets its own quote. This is what makes a difference:
- Any working-time requirements on site
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The size of the job
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
When you contact us, it’s useful to know:
- If someone has resealed it before
- Roughly how big the job is
- Pictures of the joints, sent by email
- The address or postcode of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Glazing silicone in Oval, done properly
We work across Oval on glazing joints for homes and businesses. From conservatories to shower screens, it’s the same careful method. We work on rooflights, glass balustrade bases and glass-to-glass joints, and people most often call us about stained, discoloured glazing silicone and water escaping where a screen meets the wall.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
Every job comes with our one-year guarantee.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Vauxhall station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. Schools such as St Stephen's Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Open vents or windows to let moisture out
- Don’t use a blade near the sealant
- Don’t leave a drip for the next storm
- Squeegee the shower screen after each use
Check the joints once a year. Spotting a crack early means a simpler fix, before water gets in.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Leaks from the roof covering or flashing (a roofer’s job)
- Rotten or badly damaged frames
- Condensation trapped between two panes
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Joints and surfaces we work on
- Shower screens
- Glass balustrade bases
- Conservatory frames
- Glass-to-frame joints
- Glass-to-glass joints
- Rooflights
For landlords and businesses
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.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Signs you need glazing silicone in Oval
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
People normally contact us after spotting one of these:
- Sealant that was laid over old silicone and failed
- Leaks where conservatory glass meets the frame
- Black or yellowed silicone on glass joints
- Cracked silicone between glass panels
Oval is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
